What it is

The working details

History On Board, No Phone Required

The device stores its own record. Where a Bluetooth model needs a paired handset in the room, this one logs whether anyone is there or not — and hands the record over later.

173 g and 25 mm Thick

The lightest device in the range that measures all eight parameters. It reads like an instrument in the hand rather than an ornament on a desk.

Built for Walking a Building

Survey several rooms in sequence, then read back where the levels changed. That is a workflow a spot-reading monitor cannot support.

2500 mAh, Six Hours

Four hours to full over USB-C; 173 g in the hand.

For Consultants and Facilities Teams

Where a report has to name rooms and times, on-board history is the difference between a finding and a recollection.
