The Protimeter BLD4755-5 Mini Hygrostick Probes (Pack of 5) are compatible with the HygroMaster 2, HygroMaster L, and MMS2 Moisture Meters. These probes are designed for use with concrete floor moisture measurements. The BLD5806 Mini Hygrostick Extension Lead (not included) is required for use with these probes.
- Pack of 5
- Calibration Certificate Included
- Suited for concrete floor moisture measurements
What else the mini Hygrostick needs
- Mini Hygrostick extension lead (BLD5806) — required. Mini Hygrosticks cannot be read without it, and the full-size BLD5802 lead will not do the job
- Mini Hygrostick extraction tool (BLD4755-EX) — for getting them back out of the slab
- Adjustable humidity sleeves (BLD4650-20) — the sleeve the probe sits in
- HygroMaster 2 Flooring Kit — supplies all of the above with the meter
Reusable, not single-use
Mini Hygrosticks are recovered and used again. Single-use in-situ probes are discarded after every test, so on a floor requiring three tests per 100 m² the consumable cost repeats on every job.
Meters this fits
- Protimeter MMS3 — and the MMS2 it replaced
- Protimeter HygroMaster 2
- Protimeter HygroMaster L
It does not fit the SurveyMaster, TimberMaster, Mini range, Aquant or ReachMaster Pro. Those measure moisture in materials rather than humidity in air, and take no humidity sensor.
