I have a heater similar to yours set at 78F, an outside stick on type
thermometer which says about 84F and a couple weeks ago got the $12
indoor/outdoor thermometer from Radio Shack. The Radio Shack thermometer
says 82.6F right now. The temperature varies throughout the day by about a
degree and also is affected by the room temperature. I think the Radio Shack
thermometer is probably the most accurate. It's probe is waterproof and
works great, and it's easy to hide behind a plant or filter since it's so
small. How would I test the accuracy for sure?
