General Tools LCD Moisture Meter #MM8 - Leak and Humidity Detector - Pinless and Non-Invasive

ممتاز وعملي وافادني لمعرفة موقع تسريب الماء.

كنت ارغب في معرفة مكان التسريب لدي في الجدار. لكن للأسف تجربة فاشلة وهدر للمال. ولا انصح بإستخدامه.

This is a great little moisture reader. I have tried other models and they give you some numbers and different modes for different types of material but what do you do with the numbers??? what is a "normal" reading? etc... I used this to detect possible leaks in the walls. Most moisture meters out there tend to specialize for measuring moisture in wood and various material. This one works really really well for regular dry wall! You drag it slowly along the wall near areas where you suspect there might be a leak. For my part, it discovered that while there was no pipe leak, there WAS a lot of wicking moisture from the grout in the shower to the backing drywall material (an old shower without a waterproof membrane). The meter was VERY clear. In most area, it would show 0% moisture. As I approached the shower, it gradually increased all the way to 100%... There is also a color scale indicator (from green (OK) to RED... bad/wet!). And once you pass a certain level of moisture, the meter will also beep! Like I said... NO AMBIGUITY with this device. It will tell you in simple terms: You are OK or HEY! There is excess moisture in this wall! Verdict: GET IT! Get it if you suspect moisture or water leak in a wall. At about 20% moisture, you may start having some mold in the wall. This meter is affordable... it's worth having one on hand!

Works great better than the one I bought from the hardware store

Llegó en tiempo y rápido, el producto como tal es bueno había leído comentarios de que no servía e hice pruebas antes de usarlo en el trabajo y sí funciona. Es a base de campo electromagnético que lo hace no invasivo y creo que eso mismo es lo que reduce su rango de humedad y también depende del material en el que se use, es ideal para mampostería de block, tabiques..., concreto simple, y madera. Y más que tomarlo como un porcentaje de humedad funciona como un sí hay humedad (suena) o No hay humedad (no suena).

Reading is 100% on every single wall and surface in my house. How is this possible? I'm not Spongebob Squarepants.

Use this on any surface and the readings will be high. Compared against a probe type its a mile out. Completely useless.
