Colour: MD-812 Wood Moisture Meter Verified Purchase
I recently had a new inglenook fireplace built into my cottage and had installed a multi-fuel burner in which I will be burning logs and smokeless coal. I was advised by the Hetas installer who installed my wood burner that I should buy a digital moisture meter and he recommended this one.

I am very pleased with it already. It came in a box, complete with a 9V battery and a nice carrying bag to keep it in when not in use. There is also a user guide.

The moisture meter is quite simple to operate, I figured it out prior to reading the instructions (I'm usually too impatient to read them and generally only do if I cannot figure out how to use something) and within seconds I had installed the 9V battery into the battery compartment and I was testing the moisture content of some logs I had sat in a log basket by the fire. I was pleased to see that they were all below 18%, averaging out at 14%. My installer told me only to use logs that were of a moisture content of less than 18% for maximum efficiency etc.

Its easy to operate, comes complete with batter, a spare set of pins and case and I am very happy with it.

RECOMMENDED!

Don't leave the battery in because it flattens them really quickly

This is an excellent and essentail piece of kit for anyone operating a woodburning stove. By identifying the % wetness of the wood before you use it you can avoid a lot of trouble with tar build up.

Simple to use battery operated moisture meter. Essential gadget for maximum efficiency wood burning. Simply switch on, insert prongs into chosen log and an accurate reading is taken. Wood should have a moisture level under 18% to give maximum heat output and prevent condensation in the chimney and accumulations of soot and tar in the chimney and stove
