We do not handle the sale of Thermocouple sensors.
Compatible wire sizes are as follows. Single Wire : Ø0.32 to Ø0.65 mm (AWG 28 - 22), Twisted Wire : 0.08 to 0.32 mm
2
(AWG 28 - 22), Ø0.12 mm or more in diameter, Stripping Length : 9 to 10 mm
*2:
When Auto Upload is used frequently, the measurement of the internal sensor may rise by around 0.3°C. When using external power, the data logger itself generates heat and the internal sensor will report a temperature much
higher than ambient; we recommend using an external temperature sensor in this case.
*3:
When continually used in environments with temperatures above 60°C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20°C.
*4:
Vaccine mode complies with the CDC (Centers for Disease Control and Prevention) requirements for vaccine management.
*5:
Client function. HTTP(S) proxy supported.

Battery life in the table above is for two AA Alkaline type batteries, and varies depending upon multiple factors including frequency of communication, network environment, ambient temperature, recording interval, and bat-
tery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.
