ALTEK 422

ALTEK 422 Thermocouple Calibrator. Use with transmitters, recorders, controllers, alarms, indicators, data acquisition and computer systems. Switch between 14 Thermocouple types or millivolts.

High accuracy and stability is achieved through Altek 422 exclusive isothermal block. Make your connections directly with thermocouple wire or with miniature thermocouple connectors. Field customize the Altek 422 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 Altek 422 against mis-connection to 120 Volts AC or DC, in any mode.

The Altek 422 Universal Thermocouple Calibrator turns on to the Thermocouple type last used. Other Thermocouple types may be selected each time the unit is turned on. If you use less than 14 Thermocouple types, you can create your own Thermocouple list. By following a simple setup procedure you can deselect unwanted Thermocouple types to customize Thermcouple types available at turn on.

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 Altek 422 simulates key temperatures for repetitive calibrations. “QUIK-CHEK” function stores THREE output temperatures for each T/C type (45 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 Altek 422 sets quickly without overshoot but allows slow changes at your own rate.

The Altek 422 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 Altek 422 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 422 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.
