## Questions & Answers

**Q: Want to use a tester on inside walls of caravan/campers without damaging them. Would anyone recommend this? Thx**
A: Yes. I found a small damp spot, about 150mm square and discovered a leaking roof seal. Thanks to the accuracy of the MO55 I sorted out the problem before it became a disaster

**Q: Does this have a backlit display?**
A: Thank you so much for your interest in our products. Unfortunately, this meter does not count with a backlight to increase the brightness of the display. Please learn more about the MO55 here: http://www.extech.com/products/MO55.

**Q: What is the % measurement range for both wood and building materials?**
A: Thank you so much for your interest in our products. The MO55 is able to measure moisture on wood and other buildings materials. Please find here the range for each one of them: Wood Moisture Range 5 to 50%(PIN) and 0 to 99% (PINLESS). Other Building Materials 1.5 to 33% (PIN) and 0 to 99% (PINLESS).
