Tramex Hygro-i2 Reusable RH Probe – 3 pack
The Tramex Hygro-i2® relative humidity probe is the most advanced, resilient and reusable RH probe on the market today, allowing the user to perform in-situ and hood type RH testing to comply with ASTM F2170 for the flooring industry, and is ideal for use by flood and water damage restoration and indoor air quality professionals.
The speed and accuracy of the Tramex Hygro-i2® probes set them apart from other RH probes. Together with the complete Tramex concrete moisture testing system, they bring reliability and confidence to concrete moisture testing.
Features
- Fast acclimation time
- Reusable sensors – the lowest cost per ASTM F2170 test
- Best in class accuracy, even above 90% RH
- Proven robustness, durability and reliability
- Testing per ASTM F2170 and AS 1884-2012, giving in-situ and ambient RH, temperature, dew point temperature and grains per pound
- Relative humidity range 0% to 100%
You also need an interface cable
The Hygro-i2 probe does not connect to a meter on its own – it needs the electronic interface cable, and the cable must match your meter's connector:
| RHIE2 – DIN connector | CMEX2, MRH3 |
| RHIE2B – bayonet connector | CMEX5, MEX5, DL-RHTX |
One cable serves any number of probes, so it is a single purchase rather than one per probe.
What else an ASTM F2170 test needs
- 19 mm hole liners and caps (also in a 50 pack) – one per test hole, drilled with a 3/4 inch bit
- Hygro-i2 accessory box – insertion and retrieval tool, hole liner insertion tool, metal brush, ruler and shears
- 75% calibration check salt – to verify probes before testing

Pack sizes
This listing is a 3 pack, which is the minimum ASTM F2170 requires for the first 100 m² of floor area – three test locations, all equilibrating at once. Also available as a single probe and a 12 pack.
Frequently asked questions
How many probes do I need for a job?
ASTM F2170 requires three test locations for the first 100 m² of floor area and one more for each additional 100 m². Because all locations must equilibrate at the same time, most contractors buy enough probes to cover a typical floor in one visit rather than returning to move probes between holes.
Are the probes reusable?
Yes. The probe is retrieved from the sleeve with the insertion and retrieval tool, checked against the calibration salt, and used again. The hole liner is the consumable, not the probe – which is what makes the cost per test low.
How long must the probe stay in the hole?
ASTM F2170 requires the hole to equilibrate before the reading is taken. Skipping the equilibration step is the most common cause of a result that later proves wrong. Drill, line, cap, wait, then read.
Can the same probe be used for hood testing?
Yes. The Hygro-i2 probe is used for in-situ testing in a sleeved hole and for surface hood testing with the Hygrohood. In-situ and hood methods are different tests and are specified for different purposes – check which one your specification calls for.
How do I know a probe is still accurate?
Check it against the 75% calibration check salt. Seal it in the chamber, allow it to stabilise, and confirm it reads 75% RH.
