â·ÃÊͺ¶ÒÁÃÒ¤Ò testo 720, 1 channel temperature measuring instrument Pt100/NTC, with battery and calibration protocol TESTO 720 testo 720, 1 channel temperature measuring instrument Pt100/NTC, with battery and calibration protocol Testo 720 is the single channel measuring instrument for demanding measurements in laboratories and in industry. Air, immersion and surface probes in a measurement range from -100 to +800 °C can be attached to the thermometer for different measuring tasks. In combination with the indestructible TopSafe, testo 720 is resistant to corrosive media. The glass-coated probe has proved its worth in day-to-day use in the laboratory, as it too is resistant to corrosive media. An audible alarm sounds when limit values are exceeded. Current measurement data, as well as min/max data can be printed out on site on the Testo printer. On site printout on Testo printer Continuous display of max/min values Hold button to freeze readings Display light Audible alarm (adjustable limit values) Accurate one channel measuring instrument for Pt100 or NTC probe Resistant to corrosive media with TopSafe (optional) TopSafe, the indestructible protection case (optional) Storage temperature -30 to +70 °C Operating temperature -20 to +50 °C Battery type 9V block battery Battery life 70 h Weight 171 g Dimensions 182 x 64 x 40 mm Material/Housing ABS Probe type NTC Meas. range -50 to +150 °C Accuracy ±0.2 °C (-25 to +40 °C) ±0.3 °C (+40.1 to +80 °C) ±0.4 °C (+80.1 to +125 °C) ±0.5 °C (remaining range) Resolution 0.1 °C Probe type Pt100 Meas. range -100 to +800 °C Accuracy ±0.2% of mv (+200 to +800 °C) ±0.2 °C (remaining range) Resolution 0.1 °C Temperature Testo TESTO 720 Thermometer à¤Ã×èͧÇÑ´ÍسËÀÙÁÔ à·ÍÃìâÁÁÔàµÍÃì
