Source and read Thermocouples over the entire industrial temperature range with Altek 222A Thermocouple Calibrator. Use with transmitters, recorders, controllers, alarms, indicators, data acquisition and computer systems. Each of Altek 222A is dedicated to a particular thermocouple type for error free use.
High accuracy and stability is achieved through the use of low drift components and continuous monitoring of the cold junction temperature. 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 Altek 222A to lock in 1° or provide autoranging from 0.1° to 1° with 0.1° resolution in the most used portion of the temperature range. You may also choose fixed °F or °C or front panel selectable °F/°C operation. Fuseless protection guards the Altek 222A against mis-connection to 120 volts AC or DC, in any mode.
Select autoranging 0.1°/1° or fixed 1° resolution for the full listed range of a single thermocouple type. The ALTEK 222A simulates key temperatures for repetitive calibrations. “QUIK-CHEK” function stores THREE output temperatures for real convenience. Memory is retained even when the power is off. Turn the knob to check trip points, controller action or hysteresis. The fast response Altek 222A sets quickly without overshoot but allows slow changes at your own rate.
The Altek 222A Single Type Thermocouple Calibrator display gives you fast, accurate temperature measurement with 0.1 and 1 degree or millivolts 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 Altek 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 Altek 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.
The experience of making the internet purchase was excellent. Your website is easy to navigate, checkout was simple, and delivery of the device was quick. As well, customer service (specifically your response to my email) is great!
