#1 General Tools MMD4E Moisture High Medium Low

I bought this to check the dry wall of my parents-in-law's house. A roof near their chimney leaked, causing damage to the interior drywall. Someone was called to diagnose / repair the leak, but before paying someone to repair the plasterboard, we wanted to see if the leak had really been repaired. I bought this a few days before the rain, for the first time since it was repaired, and sure enough, it found water in the damaged area. They came back to check on their work. Guy said it was the first time it leaked water (since two months ago). Of course, okay) but after I showed him pictures of 5% before the rain and + 20% an hour after the rain, I quickly went back.

#2 AcuRite 06002M Wireless Temperature Humidity

Just make sure that the weather station and the remote sensor are set to the same channel. I plugged the battery into the sensor and wondered why nothing appeared at the weather station. Channel A is set. Open the battery box at the weather station (left) and select channel B. When the wireless sensor channel is set to'B', the temperature, humidity and signal strength outside appear at the weather station. Comparing the outdoor temperature and humidity with the data published online, the reading is 100% accurate. Good range. The wireless sensor is about 50 feet from the weather station. On the whole, I am very satisfied with my purchase. For reference only, does not include 2 AA batteries.

#3 Wood Moisture Meter Detector Pin Type

I have a huge deck in my backyard and I live in the Midwest, so my deck passes through the frozen and wet and rainy seasons. This means that my decks and wooden steps must check for moisture to determine when to replace them. This hygrometer is the answer. Its accuracy and readings are accurate. But it's not easy to use. You really have to learn how to set it up for the right calibration. If you want to get the best readings, you'd better pay attention to the long-term chart it contains.

#4 Healthful Home 5 Minute Mold Test

(2015) after I found mold on some of my stored clothes, I bought this kit. I dry cleaned my clothes and put them on, but I had a growing cough and severe sinus congestion and asthma attacks in my apartment. I don't have a fever. After finding out that dry cleaning doesn't kill mold (just remove appearance), I wonder if I inhaled some mold spores on my clothes. So I bought this test, and I tested the walls of the closet where the moldy clothes were stored. Only mold was positive. After I did a blood test for Aspergillus IgG,IgM and IgE. These indicate that I have an active infection of Aspergillus. I have now struggled with internal aspergillus infections for nearly 2 years. I had to move out of my apartment and throw away most of my belongings. I took a high dose of Lugol's iodine to kill mold (200-300mg per day), took more than three months to remove mold from the sinuses (so clogged that I couldn't breathe through my nose or could not hear in one ear), and got rid of an asthma attack. Inhaling new iodine in the sprayer, taking grapefruit seed extract, staying away from sugar, high doses of vitamin C, etc., helped me cough up a lot of gray garbage plugs until my lungs now feel clear and I can lie down and sleep again at night. If it hadn't been for this test, I would still be thinking about what happened and inhaling the atomizer instead of.

#5 Klein Tools ET140 Non Destructive Detection

This is a good instrument and looks quite accurate. Something from my own experience: make sure your hands are not behind the chips you measure moisture. The reading will not be accurate; make sure that the liner on the back is completely flat with the liner you placed. It is easy to be at an angle, and if it is not 100% flat and 100% touch, the reading will be inaccurate.

#6 Calculated Industries 7445 Non Invasive Restoration

This is my first hygrometer, so I have nothing to compare, but I am very satisfied with it. I used it to check my firewood to see if it could be burned. Looks like it was built well. You have to push the fork into the wood with a little force. I'm a little worried that the little pins may be fragile, but they're not. They are so strong that the boxes seem to be up to the task. I tried-I tested a piece of wood, and then I left it at home for a while, and every time I tested it again, the moisture level dropped as you think. I like the fact that if I forget to do it, it will automatically close. A small surprise is characterized by a beep that indicates the level of humidity. If the level is really low, the beep code is slow. Then when you rise in the moisture, it beeps faster. The deadline for combustible firewood is 20%, and if the unit measurement exceeds 20%, the buzzer is quite fast. I kind of like it and say, "this wood isn't ready yet!" I should also mention that the readings I got were consistent with those I saw when I burned wood. If I measure a piece, say 18%, it lights up and burns without steam or hissing. If I measure a 22%, there will be some steam and hiss after I put it on the fire. It comes with a 9V battery, and I'm glad to see it's an alkaline battery that should last for a long time. It seems that most things with batteries are the cheapest.

#7 Moisture Dr Meter Upgraded Inductive Intelligent

I use it to measure the moisture content of wood regenerated seedlings used for guitars, which is a very thin raw material-about 3pm 16 "thick regenerated seedlings. I want to know if this is accurate in thin stocks, because the magnetic field seems to penetrate the stock, partially looking at the air on the other side. It seems that this is really happening: measurements of thin wood show that the moisture content is lower than that of thick wood, up to a maximum thickness of about 9 inch 16 "; at this thickness and above, the readings are consistent. Method: I took several sets of reseeding boards, each 3 to 16 "thick (a quad saw, though it's not expected to be any different), stacked five of them together to make thicker boards (about 1" thick), and then measured the moisture. Then I took off a 3thumb 16-inch board at a time and re-measured it. The picture shows the measurement process. Results: the minimum thickness to be accurately measured depends on the moisture content: for wood with a typical range of air-dried wood (moisture content of 5-10%), about 1 to 2 "thick wood is required to obtain accurate readings. For green materials, even if the thickness drops to 3gam16 "(the minimum thickness I have measured), the reading seems to be accurate." Specifically, the readings are consistent when reduced to the thickness of three plates (9x16 "), regardless of the moisture content-the thickness does not matter. Under 2 plates (3thumb 8 "thick), the moisture content readings of completely air-dried raw materials (moisture content 5.5%) were reduced by about 20%, and the moisture content readings of some air-dried raw materials were reduced by about 10%.

#9 Moisture DISPLAY Temperature Concrete Inspection

My daughter and her family got seriously ill again and again, and we planted it at home. They did a mold test and came back positive with mold growth on it. We need to know where the water in the house is and where the mold grows. What a job. I think there may be a product on the market that is like a stud searcher, but it can lead us to where the water or mold is. I found this incredible product on Amazon. I bought it right away, and on Saturday we dug a hole and used it all over the house. It works very well, reading out the exact percentage of humidity on all surfaces such as their home and exterior walls. I don't know how we can do this without this life table. Thank you. Thank you very much for creating this. In addition, I have contacted the company to ask if it will provide help in this regard, and received a reply on the same day. My communication with Sam is completely in line with my needs. Thank you, Sam! God bless you!

#10 Extech MO55 Combination Pinless Moisture

I use this every day for house inspection. In fact, it's probably my favorite tool. The problems I have found and the knowledge I can provide have paid a 100-fold price for it, and it is imperative to have both a pin and a no-pin mode. If it doesn't rain these days, if you don't have stitches, you'll never know if it's still leaking. The results have good reproducibility and high accuracy. One of the most beautiful things is that there is a chart on the back showing the humidity levels of different materials / patterns. This is helpful because the pinned / unpinned mode reads moisture differently, so 30% of the readings in one mode are different from those in the other. In hard-to-reach areas, beeps are a good touch. It would be nice if you could calm it down, because it would be a bit annoying to use it for a long time. Finally, power docking can be moved or redesigned. I like to take it with me often, and it's easy to open it in my pocket. It's no big deal, but when it got stuck on something in my kit, I went through it a few times. In addition, the pin cover is difficult to open, but it does prevent it from getting lost / someone glued himself to the body. I find it easiest to push forward and rotate backward, which usually pops up like this. Just make sure you don't nail yourself up.
