The Tramex Hygrohood is an insulated hood for concrete relative humidity testing. It can be used in conjunction with the TREMS-Xtra Remote Environmental Monitoring System to monitor the relative humidity and temperature of concrete and cementitious structures remotely and over time.

British Standard concrete testing

When used for RH testing of concrete floors and screeds, the Tramex Hygrohood complies with British Standards codes of practice BS8201, BS8203 and BS5325, which state that a concrete floor or screed should be sufficiently dry to allow installation of a resilient floor covering and should be tested using the insulated impermeable hood method. The Hygrohood can be used in conjunction with a Tramex external relative humidity probe and either a Tramex CMEX5 concrete moisture meter, a Feedback Datalogger, or a TREMS-Xtra monitoring system.

Hygrohood and remote monitoring with the TREMS-Xtra

The TREMS-Xtra comprises a Tramex Cloud Station, 5 CS-RHTX Tramex Cloud Sensors for ambient conditions, and 5 external Relative Humidity probes. These external probes extend the benefits of the remote monitoring system, allowing use with the Tramex Hygrohood as well as in-situ readings within building structures, cavities in walls and ceilings, and in-situ RH readings in concrete.

Each or any of the Cloud Sensors in your system can be connected to a Hygrohood on site to transmit relative humidity, temperature (deg C and deg F), dew point and grains per pound / grams per kilo readings wirelessly via the Tramex Cloud Station, enabling remote monitoring of up to 200 on-site Sensors and Hygrohoods on the Tramex Cloud platform.

Features

• Non-destructive surface RH testing of concrete and screeds
• Complies with British Standards BS8201, BS8203 and BS5325 insulated impermeable hood method
• Enables remote, long-term monitoring of concrete RH and temperature with the TREMS-Xtra
• Insulated ABS body sealed to the surface with butyl tape
• Accepts a Tramex external relative humidity probe

Hygrohood Testing Procedure

1. Before positioning the Hygrohood on the concrete or cementitious structure, the surface should be clear of any foreign materials and clean of any dust or loose materials that could affect a proper seal between the hood and the surface.
2. Using butyl tape, seal the insulated hood to the concrete surface.
3. Insert the external probe into the hood.
4. Connect the TREMS-Xtra system following the setup procedure for that system.
