Source and
read T/C’s over the entire industrial temperature range
with Altek’s Model 222A Thermocouple Calibrator. Use
with transmitters, recorders, controllers, alarms,
indicators, data acquisition and computer systems.
Built-in flexible T/C leads let you connect directly
using the proper T/C materials. Automatic, linearized
cold junction compensation virtually eliminates
temperature drift.
Field customize the Model 222A to lock-in 0.1° or 1°
resolution, fixed °F or °C or front panel selectable
°F/°C operation. Built in protection guards the Model
222A against mis-connection to 120 Volts AC or DC, in
any mode.
Select resolution of 0.1° or 1° for the full listed
range of all thermocouple types. Millivolts allows 10
microvolt resolution from -999.90 to 999.90 mV. The
Model 222A simulates key temperatures for repetitive
calibrations. "Quik-Chek" function stores three output
temperatures for real convenience. Three memories are
retained for each thermocouple type even when the power
is off.
Turn the knob to check trip points, controller action or
hysteresis. The fast response 222A sets quickly without
overshoot but allows slow changes at your own rate.
The Model 222A display gives you fast, accurate
temperature measurement with 0.1 and 1 degree or with
0.01 millivolt resolution. High resistance or open T/Cs
and leads are detected and indicated on the LCD display.
Two readings per second track fast moving temperatures.
"MAX" and "MIN" memories are continuously updated from
turn-on or whenever the "RESET" pushbutton is pressed.
The Model 222A gives you a handy tool to monitor
temperatures for drift or control deviation. Just flip
the "Quik-Chek" switch to display the minimum and
maximum temperature since reset.
Each time the Model 222A is turned on, the LCD will
display all segments for 1 second. If °C/°F operation
has been selected the currently selected temperature
scale of °C or °F will display. |
