Extra-long hole liners Tramex RHHL50X – Ø 19 × 120 mm, pack of 50

Selection guide

Pack of 50 Tramex RHHL50X 19 mm hole liners, extra long at 120 mm, with caps for Hygro-i2® probes, for ASTM F2170 tests.

Hygro-i2 probes and their accessories work only with Tramex MEX5, Tramex CMEX5, DL-RHTX. To get started with the ASTM F2170 test, choose the SP-F2170-B starter pack (3 probes, cable, calibration salt check, 12 hole liners); if you already have the instrument and cable, add HIPP probes and RHHL hole liners (Ø 19 mm, ASTM-compliant) or RHHLSR liners (Ø 16 mm, for non-ASTM tests); the HI-EX tool and HI-ACC toolbox make insertion and removal easier; SAL75 salts check the calibration of the probes.

If in doubt, contact us: our technical support team will recommend the right accessory for your instrument and application.

Integration and programming

The hole in the screed is drilled to the depth required by the standard (40% of the thickness for slabs drying from one side, 20% for slabs drying from both sides), cleaned, and fitted with the liner and cap; after acclimatisation, the Hygro-i2 probe is inserted; the reading is taken by connecting the RHIE2B cable to the instrument. With the Tramex Meters app you record position, date and values for the test report.

Calibration and repair

Hygro-i2 probes are reusable: check their calibration with the SAL75 calibration salt check (75% RH reference environment) before each test campaign and at least once a year. Liners and caps are consumables.
