CALIBRATOR The aim of SIKA engineers was to produce a range of precision calibrators that would cover the whole scope of temperature calibration. For use in harsh environments such as ships engine rooms, coal mines and steel mills Sika have produced the rugged TP17650 with a bore of 28mm diameter, 150mm deep, a range of 30C to 650C with an accuracy of + / - 0.8C, more than adequate for what is required. Temperature range: Ambient temperature up to 650 ° C. Block temperature control: digital PID controller, automatic fine adjustment, with soft-start for fan. Block temperature display: 4-digit, 2-line, 7-segment-LED 7 mm high, red and green. Display resolution: 1 ° C. Power supply: 230 VAC, + / - 10 % , 50/ 60 Hz ( Option 115 V, + / -10 % , 50/ 60 Hz)
