   Review : I purchased this meter on the advise of my wood pellet supplier as a possible means to measure the relative heat produced by various pellet brands. On checking it against my counter top room thermometers, I found that in many cases it read 2 to 4 degrees lower but I feel that this is normal as it is measuring emitted IR from a nearby surface not air temperature. Pointing it inside my refrigerator and oven appeared to give much more accurate results. Two very useful features are non-contact instant readings and automatic averaging displayed separately. A thermocouple probe is included which can be used for contact or air measurements. The thermocouple readings closely matched my room and digital meat thermometers. The meter did accurately measure the temperature of the pellet stove case but I found that moving a flat black object slowly passed the air ports, holding the meter spot on this, then reading the average result gave me a fairly accurate reading of the output air temperature. By burning a measured amount of pellets and taking the average of several timed samples, I found that six brands of locally available pellets varied over a range of 7.5% in heat output. A few percent can make a large difference in cost when burning 4 - 5 tons over a season. I feel my meter has paid for itself and I have only begun to investigate it's capabilities. Note: Yes, I could have used a meat thermometer but I would have had to fabricate a mount, could only measure one port, and they update much slower.
