Moisture Readings at Depth — Drill, Probe, Diagnose
The HI800 reads moisture deep inside concrete and mortar walls and slabs through small drilled access holes. When a surface tester cannot reach a leak path, a moisture barrier failure, or trapped moisture under flooring, the HI800 brush probes go where surface contact cannot. Built for restoration contractors, building inspectors, and facility teams diagnosing moisture problems that aren't visible from the surface.
Reads moisture at any drillable depth: Two 6mm holes spaced 30mm apart, brush probes inserted, reading displayed. Surface testers max out at 40mm of compensation — the HI800 goes as deep as you need to drill.
Concrete and mortar calibrations built in: Direct moisture readings on both materials. A separate Count mode reads electric resistance for custom calibration on materials outside the factory list.
Upper and lower alarm limits: Audible alert when readings fall outside spec — useful for systematic wall surveys where you're flagging values, not recording every point.
Hand-held with corded probe assembly: Main unit fits in one hand. Probe cable reaches drilled holes in walls, slabs, and tight spaces without repositioning the display.
