The Tramex TREMS-Xtra Remote Environmental Monitoring System monitors ambient and in-situ temperature and relative humidity remotely. Its external RH probes take readings inside wall and ceiling cavities and in concrete, so restoration contractors, flooring consultants and building managers can follow how a structure is drying without attending the site.
The kit comprises a Tramex Cloud Station router, five CS-RHTX Tramex Cloud Sensors for ambient conditions, and five external relative humidity probes. Readings upload to the Tramex Cloud platform, where they can be viewed and reported from any browser.
Kit contents
- 5 x CS-RHTX Tramex Cloud Sensors
- 5 x external relative humidity probes for in-situ readings
- 1 x Tramex Cloud Station
- Antennae for the Cloud Station
- Heavy-duty protective carry case
- Tramex Cloud software monitoring platform (tablet not included)
How the system works
On-site Cloud Sensors transmit relative humidity, temperature in °C and °F, dew point and grains per pound (grams per kilo) wirelessly to the Cloud Station, which uploads to Tramex Cloud. With an external probe connected, a sensor reports conditions inside a cavity or a slab rather than the room. The platform stores and reports your measurements, notifies you of adverse conditions, and shows status from any browser.
- Sensor battery life of up to 15 years
- One Cloud Station supports up to 200 on-site sensors
- Registration by scanning the QR code on each sensor and station into your Cloud account
- Tramex states there are no subscription fees; data is stored free for two years, after which it must be downloaded
Concrete monitoring with the Hygrohood
Any sensor in the system can be connected, through its external probe, to a Tramex insulated RH hood (Hygrohood) sealed to the slab, to monitor the relative humidity and temperature of concrete and cementitious screeds remotely over time. Tramex states the Hygrohood method complies with British Standard codes of practice BS 8201, BS 8203 and BS 5325.

The TREMS range compared
| Kit | Sensors | Measures |
| TREMS-5 | 5 x CS-RHTA + Cloud Station | Ambient RH, temperature, dew point, GPP |
| TREMS-10 | 10 x CS-RHTA + Cloud Station | Ambient RH, temperature, dew point, GPP |
| TREMS-Xtra | 5 x CS-RHTX + 5 external RH probes + Cloud Station | Ambient plus in-situ relative humidity |
| TREMS-WME/MC | 5 x CS-RHTX + 5 external WME/MC probes + Cloud Station | Ambient plus material moisture content / WME |
The choice is about what you need to prove. The TREMS-5 and TREMS-10 monitor the air. The Xtra adds probes reading relative humidity inside the structure. The WME/MC adds probes reading moisture content in the material itself.

Frequently asked questions
Do I need a separate Cloud Station for each job?
One station per site. A single station supports up to 200 sensors, so larger sites are covered by adding sensors, not stations.
Can I add sensors later?
Yes. The AP-TREMS-Xtra pack adds five more CS-RHTX sensors with external RH probes. Ambient-only packs (AP-TREMS-5, AP-TREMS-10) can be added to the same station.
Is there an ongoing platform cost?
Tramex states there are no subscription fees and that data is stored free for two years, after which you need to download it. Platform terms are set by Tramex and can change, so ask us to confirm the current position before committing to a long monitoring contract.
What happens if the site loses internet?
This is worth checking against your site conditions before quoting a monitoring job. Contact us and we will confirm the current connectivity requirements with Tramex rather than guess.
TREMS is a system rather than an instrument, and the right configuration depends on the sites you monitor. Contact Carpet Cleaners Warehouse before you order and we will size it against your work.
