The TR-31( Temperature ) and TR-32 (Temperature and Humidity) are
compact data logger with built-in lithium battery for recording 43,000
values. TR-31/32 adopts user-friendly USB interface, easy-to-mount
brackets with screws. The OK key can help the user check the
Max/Min/Current values and the upper and lower limits. The measuring
data can be recorded automatically at adjustable intervals from 2 s up to
24 hours.   The saved measurement values can be read out via a USB port
and graphically displayed using the equipped software, or exported to
other software applications for further analysis.
