Recording -4 to 158°F alongside 0 to 100 %RH over Bluetooth, this data logger documents storage climate from up to 98.4' (30 m) away. In addition, HACCP International certification supports food safety documentation. Two internal channels log both parameters to 16,000 readings without shortening either.

Monitoring a storage room or a plant system starts with a record nobody has to take by hand. This 174 H BT 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
Bluetooth reaches up to 98.4' (30 m), so readings come off the logger without opening a cold room door or reaching a ceiling-mounted sensor. The free testo Smart App on iOS and Android handles configuration, live display and report export.
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.
