High accuracy dual channel thermometers feature 0.01° high resolution with accuracy of ± 0.30°C. Individual channels provide simultaneous monitoring of temperatures in separate locations. Display exact time and date when a min/max reading occurred and alarm sounded. Min/Max temperatures are programmable in 0.1°C increments over entire range of -50° up to 70°C. Temperature buffered solution probes contain a non-hazardous glycol mixture that eliminates rapid temperature changes when opening refrigerator or freezer door. Available with one miniature size sensor that is chemical resistance and waterproof for use in water baths, incubators or dry block heaters. Supplied with Traceable Calibration Certificate (NIST), stand, mounting strips and battery.
