Checktemp water resistant digital thermometer with stainless steel penetration probe and 3.3' silicone cable C/F


The Checktemp® 1 Digital Thermometer - HI98509 is a high-accuracy thermometer with a 1 m (3.3’) flexible, silicone cable connecting the meter and the stainless steel probe.  The probe incorporates an NTC thermistor sensor to measure the temperature. 

Thermistors make it possible to obtain extremely high accuracy in a very short period of time. The Hanna CAL Check™ feature has been incorporated into the Checktemp®1 for reliable and accurate measurements. CAL Check™ automatically runs a self-check upon startup and reports status back to the user; "-0-" for ok and "Err" if something is wrong. 

Checktemp®1 makes routine controls fast and simple for both incoming and outgoing goods. Constructed of AISI 316 stainless steel material, this probe is in compliance with food regulations, making it an ideal instrument for measuring temperature according to HACCP requirements.
