Surface sensorThe room and the surface, measured by one sensor.
The Surface sensor measures ambient temperature and humidity in the room and adds one external temperature probe. Fix the probe flat against a wall, a pipe, or a shelf, or place it in a fridge or freezer, and you see the surface and the room side by side on the RoomAlyzer platform.

Why choose this sensor?
Two measuring points, one sensor
The housing logs the room climate while the contact probe measures surface temperature from −55 to +125 °C, on a wall, a pipe, or a shelf, or in a freezer at −40 °C.
Documentation you can rely on
±0.5 °C on the probe and ±0.2 °C in the room, with drift under 0.1 °C a year, so stored readings hold up when an auditor or conservator asks for them.
No gaps in the record
The sensor stores up to 100,000 readings and sends them over NB-IoT, so a weak signal behind a fridge door does not leave holes in your data.
Zero IT hassle
Up to 8 years of battery life on a replaceable pack, 3M adhesive pads for mounting, and no Wi-Fi or gateway to set up.
Example use cases
Medical fridges & freezers · Pharmaceutical stores · Laboratories · Archives & server rooms
