Temperature and humidity logging

The CEM DT-172 records ambient temperature from minus 40 to 70 degrees Celsius and relative humidity from 0 to 100 percent RH. It stores up to 32000 readings split evenly between the two channels at intervals ranging from one second to 24 hours. A built-in display shows live values while the logger runs on a battery rated for roughly three years of typical use. Windows analysis software covers legacy systems from 98 through 7.

Environmental monitoring and K-type probe work

Technicians who need simultaneous room-condition tracking and high-temperature probe measurements will find the dual-channel memory and wide K-type range useful. Users who require modern operating-system drivers, Bluetooth connectivity or an English manual in the box should look elsewhere because the supplied software targets older Windows versions and the package excludes both batteries and localised documentation.

32000-reading memory capacity

The logger holds 16000 temperature samples and 16000 humidity samples before overwriting the oldest data, so the chosen sampling interval directly determines the maximum unattended logging duration.

Questions about this item

Does the DT-172 package include the batteries needed for its 3-year typical battery life?

The standard package excludes batteries due to air-shipping restrictions; buy AA cells locally before first use.

Should I choose the DT-172 or the 172TK variant for tighter temperature accuracy?

The 172TK model improves basic temperature accuracy to ±0.5 °C versus ±1 °C on the standard DT-172.

How does the 32 000-reading memory translate into logging time when recording both temperature and humidity?

Memory splits into 16 000 slots per channel; at a 1-second interval that gives about 4.4 hours of dual-parameter logging.
