Protimeter BLE Bluetooth Temperature and Moisture Logger

The Protimeter BLE Bluetooth Temperature and Moisture Logger is designed to be installed around a building in order to monitor the environment. It is capable of measuring moisture content in wood and other building materials from 8% to 30% WME (±1%) as well as air temperature from -20˚C to 50˚C and relative humidity from 0 to 100%.

Up to 1000 readings can be saved to the Protimeter BLE’s internal memory with logging set at a user adjustable interval. Readings are communicated via a Bluetooth connection (up to 10m) to a free app on an Android or iOS smart device.

Multiple loggers can be saved to the app at any one time and it provides numerous useful analysis settings, for example detecting mould-friendly conditions, monitoring building moisture health, and protecting buildings and artefacts.

The Protimeter BLE benefits from a sturdy design and has an IP65 ingress protection rating which prevents dust and water ingress. The logger is covered by a 12-month warranty. A quantity discount is available for packs of 20.

Protimeter part number: BLD2025 / BLD2030
