User questions & answers
Question: | Does this meter have a function to correct for different densities / species of wood, or does this need to be done manually or table lookup |
Answer: | This tool is designed to measure the moisture content in wood. You have to press the prongs in tight to get a good reading. I suppose you could try it on drywall and take your readings at different drying times. It will leave small indentations in the surface which will have to be filled. |
Question: | Does this product come with a carrying case? Extra pins? Battery |
Answer: | This meter uses 2 metal pins to penetrate the surface of the material you want to measure. It can't 'see through' material. It actually has to touch the material to be able to measure the moisture level of it. The pins are about 0,5 to 1 cm long so you can not reach through walls. |
Question: | Can I use it for drywall |
Answer: | I was told "Made in USA' with some items from other countries. As for accuracy, unless you have some means to test against a known accurate gauge, I guess you have to take their word on that. It has worked OK and matches the TPS on my E350. As long as a digital tire gauge is consistent in its' pressure readings, you are matching each tires pressure. Exact pressure is not as critical as consistency from tire to tire, IMO. I purchased this gauge based on what I feel is decent quality, reasonable accuracy / consistency, "Made in USA", ease of use and reviews. So far, I am satisfied. I also ordered this to store it in.

Question: | Can this measure moisture through walls and baseboards? If so how many centimetere in can it measure moisture |
Answer: | No, it does not come with a storage case |

User questions & answers
Question: | Are any of these see-through |
Answer: | It is a bit boxy especially between the underarm and bust. It has that tug of material and doesn’t shape well in this area. It definitely doesn’t taper in at the waist as shown on model. |
Question: | Is the shirt soft, not stiff |
Answer: | I wear a women's medium (5'6" 131 lbs) and ordered a large, as I wanted a looser fit. This was still a really tight fit and the neck felt very uncomfortable, almost like it was on backwards (I confirmed that it wasn't). I really don't think these are true to size. I bought three for work and these looked and felt like junior sizes, not women's. "Nano" does mean "a very small item by one definition, so I think I was shafted. |

User questions & answers
Question: | what are 2032 batterys used for |
Answer: | 2032 batteries are often used on computer motherboards to keep the clock running and to store BIOS settings. |
Question: | It says 2 count (pack of 6). How many total for 1 order |
Answer: | 12 |
Question: | are these the same as dl |
Answer: | Yes. The difference between DL2032 and CR2031 batteries is that the "DL" means it's a Duracell battery as shown. Any of the 2032s from known producers, like Duracel, Energizer, Ray-O-Vac, Panasonic, and the rest have a similar quality of construction. I'd stay away from brands I didn't know. Cheaper batteries are just that, "cheaper" in price and in quality. |

User questions & answers
Question: | Do these replace the Panasonic CR1616 3v battery |
Answer: | They work in my Chrysler remote. Just make sure its the correct size for your remote. A word of caution: my remote lasted about 10 years with the old battery. The one I got from amazon is already giving me problems (less than 1 year). |
Question: | What kind of packaging are these in |
Answer: | The 2016 represents the physical size of the battery while the alpha characters are unique to a given manufacture. All of DuraCells lithium coin batteries use DL as a prefix while others use their own or a generic prefix. |
Question: | Are these the batteries used for auto remotes |
Answer: | I haven’t noticed anything yet. I figure they’re also on the ceiling and don’t receive direct sunlight so they’ll probably weather well. I’ve had ours for about a year now. |
Question: | This item description is DL2016, but the package shown is CR2016. Which is it |
Answer: | 6.3 in. |
Product description
The General Tools MMD4E Pin-Style Digital Moisture Meter provides accurate moisture level reading to detect leaks, dampness and moisture in wood, walls, ceiling, carpet and firewood. It is an essential tool for assessing water damage and remediation efforts after flooding from storms, hurricanes, roof leaks or broken pipes to discover hidden water damage in floors, walls and under carpets. By checking suspicious water stains with a moisture tester around the house, you can determine whether the area is wet (a perfect breeding ground for mold) or has long since dried. This water leak detector also is helpful for new home inspections and home restorations, locating roof leaks or simply to ensure firewood is ready to burn. It also ensures the appropriate level of surface dryness before painting, sealing or treating wood or drywall. The moisture meter is easy to use: simply stick the stainless steel pins into the surface of what you are measuring in order to get a read-out. Overall measurement range of 5 to 50% for wood and 1.5 to 33% for building materials. The backlit, large, easy-to-read digits and clearly-designed LED alerts tell you immediately if the moisture content is high, medium or low. Plus, the moisture meter has audible high, medium, low alerts so you will be able to hear the level even if you are in a dark or awkward space where you can’t see the screen. The sturdy, ergonomic shape and rubber side grips allow for comfort even when using for multiple measurements. Every moisture meter also feature a hold function to freeze a reading to read later, auto power off and a low battery indicator. Every package includes extra 0.3 in. (8mm) stainless steel pins, a protective cap that doubles as a calibration checker and a “9V” battery.

User questions & answers
Question: | made in USA |
Answer: | Nathan, Thanks for the question. The Moisture Range on this Hand Held meter for CORN is 10 - 40%. However, the clear plastic funnel which is provided to assist with consistent filling of the test cell, will not work well on corn over say 25 - 30%. This is due to the lack of flowability in the higher moisture content. I would suggest that you still fill the funnel, but pour the sample back out the large end at just 1 - 2" above the test cell. EVERY TIME and at the same Rate. With this consistency, you would have much greater repeatability between different tests. I would also suggest using the feature to average three readings to allow for some fill variation. Hope that this has help with the operation of the meter. Tom Runyon Seedburo Equipment Co. |
Question: | I have a wooden floor that is swelling little bit. I know I had a small water leak. Can this tool help me to check if there is moisture underneath |
Answer: | Not on the standard instrument, but YES, Long Grain and Medium Grain Rough Rice have recently been added to the available Calibration list. These would need to be substituted on the list, for example, Oats and Milo could come off and we add in the Long Grain & Medium Grain Rough Rice. Just let us know at the time you place your order and we will make this substitution free of charge. Seedburo Equipment Co. |
Question: | Can I use this product to rule out a plumbing leak under my concrete bathroom floor. The outer bathroom wall is concrete & paint is bubbling |
Answer: | Es el mismo equipo, la unica diferencia es que el GACMINI2500 es mas preciso. |
Question: | accuracy |
Answer: | Thank you for your question. No, the GACMINI testers do not test frozen grains, only the GAC2500UGMA or GAC2500AGRI have the capability of reading this much lower temperature and compensating for this in the calibration. You can view a list of the available calibrations for the MINI testers at the following website: http://cal.dickey-john.com/calibrations.aspx Please let us know if you have any other questions - Kathy at Seedburo Equipment Company |
