Testo 922  dual input type K differential Thermometer

testo 922 Dual Input Type K Thermocouple
Differential Thermometer

Testo 922 2-channel thermometer. Displays both channels or temp difference between channels

testo 922 Dual Probe thermometer simultaneously monitors two K-type T/C. Can display temperature of both probes or temperature difference between probes. Used for HVAC, A/C, refrigeration systems, cold storage applications and frozen food storage monitoring. Useful for monitoring temperature differences when cooking foods or other heating applications. Display resolution +/-0.2 F over range -58 F to +390 F; +/-2 F over range 390 F to 1830 F.

Advantages
  • 2 probes can be connected (Type K thermocouple)
  • Backlit display for T1, T2 and differential temperature
  • Optional wireless measurements
  • Timed interval (1 to 60 min)
  • Printing with optional printer
  • User adjustable audible alarm
  • HOLD button
  • Optional TopSafe case protects instrument from dirt, water and impact
