Dual function CA20
Thermocouple Calibrator can be used to source Type J thermocouple
output values or measure Type J thermocouples. Quickly select
output value using the rotary switch with coarse and fine adjustments.
Model CA20 accepts up to two Type J thermocouples and features
data hold and max functions. Measurements are displayed in a
3½-digit backlit display.
Units include a 4" (100 mm) Type J bead wire temperature probe,
calibration cable, 9 V battery and instruction manual.
