Catalytic Thermometers

Our innovative design measures gas temperatures right after the gas passes through the combustor so the temperatures reflect the combustor's temperature. It registers accurate readings up to 2000° Fahrenheit, and can be retrofitted to most catalytic stoves to comply with Environmental Protection Agency regulations. An indispensable tool for efficient woodstove operation, our thermometer signals when to switch off bypass, and when to reduce fire to prevent damage to combustor. It also indicates declining performance of a failing catalyst and the need for replacement.

Catalytic combustor probes are manufactured of copper for fast heat transmission, then plated for corrosion resistance. The probe end may be placed up to a half-inch away from the combustor, but should not touch it. Offered in various lengths to fit all brands. Consult instructions provided by your stove manufacturer before installing. Made in the USA.

Catalytic probe thermometers lengths are measured as shown below. The probe length that enters the stove is shorter than the overall length. Thermometer probe should be positioned 1/2 inch from the combustor.

If you need help determining the catalytic combustor you need contact us.
