โทรสอบถามราคา testo 922, 2 channel temperature measuring instrument T/C Type K, connection of an optional radio probe, with battery and calibration protocol TESTO 922 testo 922, 2 channel temperature measuring instrument T/C Type K, connection of an optional radio probe, with battery and calibration protocol The differential thermometer records temperature values from 2 connected thermocouple probes and displays them simultaneously. The reading from an additional temperature probe can also be wirelessly displayed in the testo 922 measuring instrument; i.e. measurement data is transmitted by radio. Differential temperature can be called up immediately. Current measurement data such as max/min data can be printed on the Testo fast printer on site. It is possible to print measurement data once a minute, for example, on the printer if cyclical printing is in operation. 2 channel measuring instrument with optional radio probe Displays differential temperature Cyclical printing of readings, e.g. once a minute Continuous display of max/min values Hold button to freeze reading TopSafe, indestructible case, protects from dirt and impact (option) Display light On site printout on Testo fast printer Storage temperature -40 to +70 °C Operating temperature -20 to +50 °C Battery type 9V block battery, 6F22 Weight 171 g Dimensions 182 x 64 x 40 mm Material/Housing ABS Probe type Type K Meas.
