The PYRO Analog Thermocouple Thermometer is a rugged portable easy to read thermocouple pyrometer that utilizes interchangeable and reusable thermocouples for temperature measurement. This analog pyrometer is ideal for temperature measurement using thermocouple thermometer type J thermocouples. Temperature measurement accuracy to ± 1.0% of reading is achieved by employing an automatic internal cold end junction compensator to prevent temperature measurement errors due to ambient temperature variations. The PYRO Surface Pyrometer comes complete with a rugged cast aluminum housing and is ready to use with a wide variety of optional rigid & flexible extension arms and rugged type J thermocouples.
