THERMOCOUPLE

Model 222A Single-Type Thermocouple Calibrator

Model 322
4-Type Multiple Thermocouple Calibrator

Model 422
14-Type Universal Thermocouple Calibrator

Most Accurate Handheld T/C Calibrators!

  • Calibrate All Your T/C Inputs—
    Alarms, recorders, controllers and indicators with 0.1° resolution. 
  • Built-In T/C Thermometer—
    Connect the T/C and accurately read the temperature. Instantly recall the minimum and maximum temperatures at any time to check the process.
  • Unparalleled Accuracy—
    422 & 322 ±(0.008% of reading + 0.006 mV).
    222A ±(0.016% of reading + 0.006 mV).
    Accurate to ±0.2 °C/0.4 °F for types J, K, T, E, N, L & U.
    Accurate to ±0.7 °C/1.3 °F for types R, S, B, G, C, D & P. 
    Millivolt range accurate to ±0.006 mV!
  • Quik-Chek Switch—
    Instantly recall three output temperatures per type.
  • Automatic Cold Junction Compensation—
    Miniature T/C connector and screw terminals on Models 422 and 322 for stable connections to exclusive Isothermal Block. Model 222A comes with attached thermocouple extention wire for fast and stable connections.
  • Display Directly in °C & °F—
    Model 422—14 types J, K, T, E, R, S, B, N, C, G, C, P, L, U & mV. 
    Model 322-1—four types J, T, E, K & mV. 
    Model 322-2—four types B, R, S, K & mV. Model 222A—single type—choose from J, K, T, E, R, S, B, N, C, L or mV.
  • Optional Wire Kits with Miniature T/C Connector On One End—
    Kit-1 types J, K, T, E. 
    Kit-2 types B, R/S, K.
