Altek 322 Shown
read T/C’s over the entire industrial temperature range
with Altek’s Model 322 Thermocouple Calibrator. Use with
transmitters, recorders, controllers, alarms,
indicators, data acquisition and computer systems.
Switch between four T/C types or millivolts.
High accuracy and stability is achieved through Altek’s
exclusive isothermal block. Make your connections

Field customize the Model 322 to lock-in 0.1° or 1°
resolution, fixed °F or °C or front panel selectable
°F/°C operation. A shrouded miniature thermocouple
connector receptacle plus terminal screws allow for easy
hookups. Built in protection guards the Model 322
against mis-connection to 120 Volts AC or DC, in any
The Model 322 turns on to the T/C type last used. Other
T/C types may be selected each time the unit is turned
on. Other T/C types may be selected each time the unit
is turned on. If you always use just one T/C type, lock
in the selected T/C type with the internal DIP switch to
prevent accidental change to an unwanted type.
Select resolution of 0.1° or 1° for the full listed
range of all thermocouple types. Millivolts allows 1
microvolt resolution from -99.999 to 99.999mV. The Model
322 simulates key temperatures for repetitive
calibrations. "Quik-Chek" function stores three output
temperatures for each T/C type (15 total) 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 322 sets quickly without
overshoot but allows slow changes at your rate.
The Model 322 display gives you fast, accurate
temperature measurement with 0.1 and 1 degree or with
0.001 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 322 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 322 is turned on, the LCD will
display all segments for 1 second. It then displays the
currently selected thermocouple type or mV for
approximately 3 seconds. If °C/°F operation has been
selected the currently selected temperature scale of °C
or °F will display.
