HQRP 2-Pin JT-2G Moisture Analizer Gauge Tester Wood / Drywall and Home Inspection Tool plus HQRP Coaster Review

Average Reviews:

(More customer reviews)This meter is terrible. First, listen to some quotes from the tiny 4 page "manual".
"Thank you for purchase our Products. Please read this manual first before use it. It will tell you how to use it and simply inspect it so as to exert the ruggedization and durable of it's merit..."
Seriously, I'm not making this up! By the way, the poor grammar is not mine! I'm typing this stuff word for word.
Now listen to #6 on the "Notes" page;
"It has a large impact on wood moisture in some conditions, such as Special wood, different temperature, the wood growing up in different place. The simple moisture meter is just based on one kind of wood, and it has not the correction function on Special wood, different temperature, the wood growing up in different place. So the different meter will have the different measuring value."
Now tell me, WHAT????
So when I tell you that the meter gives me a different reading from one side of a piece of split wood to the other, it seems that from the above statement it's not the meter's fault.
I mean how do I know if I have "Special wood"? Or if my wood "grow up in different place"?
Sorry, this meter, as well as it's useless manual, was a waste of my money.
And none of the "simple moisture meter is just based on one kind of wood" talk can be found on the page you view when you order the product.
My unit has the word REMODIFICATION! on the serial number label. I didn't see that on the order page either.
Buy a better meter than this. And I would recommend one made in the good ole USA!

Extech 445815 Humidity Meter with Alarm and Remote Probe Review

Average Reviews:

(More customer reviews)I am a Chocolate Chef (Chocolatier) professionally, and temperature and humidity is vitally important to my product turning out. We purchased this item in hopes of the helping to locate humid spots in our production kitchen and found that this meter was perfect for that.
The probe is fantastic and incredibly accurate, and the meter refreshes at an incredible rate. We ended up buying two more for the retail area, and the storage area. Fantastic product!

General Tools MMD5NP Non-Invasive Moisture Meter Review

Average Reviews:

(More customer reviews)I was excited to receive this moisture meter, as I had a set of resawn walnut boards to check for uneven moisture content on the inside and outside faces. My excitement turned to mild concern when I started to read the instructions: "Press either button to active the sensor". OK, I can roll with that, I guess, although a later item, "Buzzer sounds when the reading changes every increasing digit" left me somewhat bemused. Funnily enough, the instructions also included a disclaimer: "Notice: we are not responsible for typographical errors". Um, OK, then who is responsible?
Anyway, I "actived" the sensor, pressed it as described to one of my boards and...got a reading of 59.9% (the maximum). "Hmm", I thought, "those boards have been drying for two years - that can't be right." So, I tried a piece of beech, nice and dry when I bought it, that's been in my shop for a year or so, planed mirror smooth and thus eliminating the chance that a rough surface could be the problem, and got a reading of 8.0%. "That's more like it!", I thought, "Maybe my first attempt was a just a fluke." Then I re-measured the beech that had given me a believable reading. This time, I got 14%. Another attempt netted me 29%, then 7.4%. So, I tried a few other pieces of wood, with similarly wildly varying results. Fooling around with the unit, I found that pressing more on one corner or the other would cause huge swings in the reported measurement. When I held it in my left hand, I got a different result than when I held it in my right hand. Five minutes later, it was back in its box and on its way to the Amazon returns department.
Maybe this was just a defective unit. Who knows?

Johnson Level & Tool M391 English/Metric Aluminum Meterstick Review

Average Reviews:

(More customer reviews)I was hoping it would be a little sturdier (thicker). For this price, it's not too bad. If you're using it in a setting where it won't be abused, it's great. For field biologists like myself, it will at least work until it gets bent. Then again, wooden meter sticks break, so there isn't really a perfect product out there yet.

HQRP JT-4G Wood / Firewood Moisture Meter - Wood, Firewood, Wall Damp Meter 4-Pins and Home Inspection Tool Review

Average Reviews:

(More customer reviews)I bought this meter about 1 month ago because my firewood was not burning as well as I had hoped, and I wanted to diagnose the problem. I have found the JT-4G meter to be useful for this purpose.
I can't vouch for the absolute accuracy of its readings (I don't have an independent method for testing this), but at least the relative values make sense. My logs, nominally 16" long and mostly oak, maple and some birch, were split and dried for 1 or in some cases 2 seasons (in Massachusetts, during two unusually wet summers). The moisture readings at the cut ends are typically around 15-20%, which is within the recommended range for firewood. However, when I re-split them to diagnose the problem, I found a consistent pattern of higher moisture readings in the middle of the newly exposed surfaces (typically 25-30%). Thus, the meter has confirmed that my logs are drying primarily from the cut ends and that they have not been dried for long enough. Birch logs gave lower readings than oak or maple - perhaps because birch dries better or perhaps because the calibration of the device is not absolutely precise across different tree species. Commercial pine lumber (2x4's) gave readings around 5% or lower - ie much drier, as one would expect.
I also checked whether the orientation of the pins relative to the grain makes a difference, ie whether you align the long gaps with the grain or across the grain, or whether you stick the pins into the transverse cut such that they are parallel to the rain. In general my readings were consistent between the three orientations. So the orientation doesn't seem to matter.
The meter is easy to use. The 4 pins seem reasonably strong, although my intuition is that they could probably bend if I pushed with maximum strength. You do need to push a bit - I find that if they are not properly pushed into the wood, I get artifactually low readings. My sense is that once they are pushed in beyond 1mm or so, further pushing has little effect (that's important - the meter would be unreliable if the reading were proportional to the force, but once beyond a certain threshold I don't think this is the case).
Minor gripes - the yellow cap is difficult to remove, and the instructions are written in poor English, although the meaning is clear enough. It recommends checking the calibration by pressing it onto your fingertip - this worked as advertised. (I wonder whether the reading depends on skin conductance, and whether you could also use the device as a polygraph. But that's an experiment for another day....)
There are much more expensive meters available - I assume woodworkers who care about precision or about not scratching the surface would choose those more expensive models. But for testing your firewood this one seems to get the job done.
