Recording -4 to 158°F alongside 0 to 100 %RH, this data logger documents storage conditions for food, archives and climate-sensitive goods. In addition, two internal channels log both parameters to 16,000 readings without shortening either. Automatic backup protects measurements when the battery runs down.

Monitoring a storage room or a plant system starts with a record nobody has to take by hand. This 174 H mini data logger records temperature and humidity across -4 to 158°F (-20 to 70°C) and holds 16,000 readings, enough for months of unattended logging.
Readout without disruption
A USB connection transfers data to ComSoft Basic, free to download, or to ComSoft Professional for deeper analysis. Both export to Excel and generate PDF reports for audit files.
Nothing lost to a flat battery
Automatic data backup preserves the record when the battery runs down or is changed. A IP20 housing and a wall bracket suit permanent installation, and the white housing distinguishes it at a glance where several loggers are deployed together.
