|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.
