Temperature data logger TR-81


The TR-81 is designed for use with three wired platinum resistive sensors.
PT-100 sensor measurement range can be measured by attaching -200*C and 600*C and two sensors in between.
Also, we can adjust the length of the protective pipe of the sensor, the protective pipe diameter and the cable length according to your needs.

Key features

-Can measure and record from -200 to 600*C.
-1 unit has 2 measurement and recording channels.
-Recording interval 15
-Large logging capacity
-5-8 months continuous recording on 1 battery
-Stable backup function
-Easy to read multifunction display

Application example

-Melting temperature while preparing food with cooking pots and pans
-Temperature management of cryogenic freezers
-Temperature management for blood tranportation
-Compost temperature management
-Boiler pipe temperature recording
