SOURCE and READ Thermocouple’s over the entire industrial temperature range with Altek 322 Multiple 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 directly with thermocouple wire or with miniature thermocouple connectors.
Field customize the Altek 322 to lock-in 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 Altek 322 against mis-connection to 120 Volts AC or DC, in any mode.
The Altek 322 Thermocouple Calibrator turns on to the T/C type last used. Other thermcouple types may be selected each time the unit is turned on. If you always use one T/C type, lock in the selected T/C type (ex. type J) with the internal DIP switch to prevent accidental change to an unwanted type.
Resolution is 0.1° or 1° over the full listed range of all thermocouple types. Millivolts provides 1 microvolt resolution from -99.999 to 99.999mV. The Altek 322 simulates key temperatures for repetitive calibrations. “QUIK-CHEK” function stores THREE output temperatures for each T/C type for real convenience. Three output values are remembered for each T/C type & MV for a total of 15. Turn the knob to check trip points, controller action or hysteresis. The fast response Altek 322 sets quickly without overshoot but allows slow changes at your own rate. Memory is retained for each thermocouple type even when power is off.
The Altek 322 Multiple Thermocouple Calibrato 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 turnon or whenever the “RESET” pushbutton is pressed. The Altek 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 Altek 322 is turned on, the LCD will display all segments for 3 seconds. 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.
