Altek Model 22 Thermocouple Sources provide 22 precise
temperatures for inputs to transmitters, recorders,
controllers, alarms, data acquisition and computer
systems. The Model 22 provides thermocouple wire output
and is cold-junction compensated for ambient temperature
variations. Conformity to the particular thermocouple vs
millivolt curve is in accordance with the latest ASTM
and IPTS standards for exact temperature simulation.
Thermocouple types B, E, J, K, R, S and T are available
in both degrees F and C. Resolution is 25, 50 or 100
degrees, corresponding to full scale output of 500,
1000, 1700, 2100 and 3100 degrees respectively.
Dual ranges, with an individual "ON" position for
each range allow quick, easy settings for any output.
Calibrated accuracy is ±0.1%
span of ±1 degree. Negative
temperatures add ±2 degrees.
Two built in AA cells provide power for one year of
everyday use. A front panel LED pulses every time the
Model 22 is turned on to indicate proper battery
voltage.
The low cost Altek Model 22 is a complete, compact
source for checkout and calibration of all thermocouple
instruments in the field, shop, or control room. |
