Thermochron Connection

Providing Thermochrons and temperature monitoring solutions

Thermochron iButtons

Thermochron iButtons are small yet robust temperature loggers capable of monitoring a wide range of temperatures from up to 140°C to -40°C. Key differences between Thermochron models include:

Temperature Accuracy

±0.5°CThe DS1922L, DS1922T, DS1923, and DS1925 feature an accuracy of ±1.0°C and larger memory capacities
±1.0°CThe DS1921 family are the most economical with an accuracy of ±1.0°C
±7.0°CThe DS1922E has an accuracy of ±7.0°C. It monitors the highest temperature range of all Thermochron models.
Temperature Operating Range

-40 to 85°CThe most flexible temperature range. Supported by 3 models: DS1921G-F5#, DS1922L-F5#, and DS1923-F5#
-25 to 70°CThese are 💧waterproof💧 thermochron models: DS1921G-WP, DS1922L-WP, and DS1925-WP
-20 to 85°CThe DS1923-F5# which is the only model with both temperature and humidity
-5 to 26°CThe DS1921Z-F5# budgetary priced for monitoring cool temperatures
15 to 46°CThe DS1921H-F5# is budgetary priced logger for monitoring body temperature of humans and animals and temperature sensitive processes like curing, powder coating, and painting
0 to 125°CThe DS1922T ideal for monitoring high temperature processes like cooking and pasteurization.
15 to 140°CThe DS1922E is ideal for monitoring autoclave sterilization processes and other industrial processes surpassing 125°C
Water-Resistance

IP56All Thermochron iButtons are protected from splashing/spraying of water
IP68This level of protection is provided by a protective capsule
IPX8Our WP line of Thermochrons are protected against continuous water submersion for up to 30 meters.
Logging Capacity & Resolution

The Thermochron iButton’s logging capacity is determined by Temperature Resolution and Humidity Resolution (if applicable) selected at the beginning of each mission. The tool below assists you in determining how selected resolutions affect the total number of readings each model can hold and the duration before the memory becomes full.
