This special Comark kit comes with a KM340 differential thermometer, carrying case and probes needed for measurement.
The Comark KM340 is a handheld industrial-grade thermometer that uses type K thermocouples to generate measurements of temperature in both Celsius and Fahrenheit. It is a twin input thermometer, allowing two probes to be inserted and two measurements to be calculated simultaneously.
HVAC professionals will find this thermometer particularly useful for testing heating, ventilation and air conditioning for both new and existing installations.
