Tramex CRH Concrete Moisture and Humidity Test Kit

CRH Moisture Content Test Kit Features & Benefits:

• Non-Destructive moisture measurement of up to 7% in concrete in increments of 0.1%.
• RH Probe for measuring simultaneous readings for Humidity (%RH) in addition to Temperature and Dew Point.
• Instant readings on clear LCD display.
• Stores up to 900 recorded readings in 30 files. Recorded readings can be recalled and displayed on LCD.
• Download recorded reading to pc for transfer to word processing or spread sheet word processing or spread sheet for archiving data or report writing. For use with sub-surface In-Situ method (ASTM F 2170) or non-destructive hood method (ASTM F 2420).
• Complies with BS Standard BS5325:2001 and BS 8203:2001 for above surface readings of RH, temperature and dew point readings.
• “Hold” freezes reading on digital display.
• Battery operated (supplied)

CRH Moisture and Humidity Meter Kit Includes:

• CRH - Digital, hand held, non-destructive concrete moisture meter.
• RHP - Two relative humidity probes.
• AZHR75 - Calibration check salts for RH probes.
• RHSK - One dozen RH Sleeves for in-situ (ASTM F 2170) testing.
• Tramex Case - High impact, polypropylene carrying case, with die cut foam lining.

(Does not include infrared thermometer - we recommend IRT206)

The Tramex CRH Moisture/RH Meter enables you to carry out 4 individual tests:

1. Measure non-destructively and instantly the moisture content in concrete and gypsum flooring
2. Measure the relative humidity, temperature and dew point within the floor slab or screed using the (below surface) In-situ method
3. Measure the relative humidity, temperature and dew point above the surface of the floor slab or screed using RH hood test methods (RH Hood Sold Seperately Item# RHIH)
4. Measure the relative humidity, temperature and dew point of the environment that the floor is being installed

The Tramex CRH allows you to carry out the most appropriate tests

HOW DOES IT WORK

In MOISTURE MEASURING MODE it uses the principle of electrical impedance measurement to give accurate non-destructive moisture readings in concrete and gypsum floor screeds.

From Electrodes with special spring mounted probes on the base of the instrument, a low frequency signal is transmitted into the material being tested to measure the electrical impedance.

In HYGROMETER MODE it uses a solid state capacitive sensor RH probe to give accurate and fast relative humidity and temperature readings. While being easy and uncomplicated to operate the CRH has a powerful micro controller, which processes the information received and accurately calculates the moisture content, relative humidity, temperature and dew point and displays it on the clear digital display.

It has a high capacity non-volatile memory chip which stores and retains its data.This information can be recalled at any time by scrolling and reading directly from the instrument`s own display or downloaded to a PC for storage and inclusion on spread sheet or report.

NEED FOR THE TRAMEX CRH

Excessive moisture in concrete floor slab and screeds can lead to a host of problems in all types of floor coverings such as: adhesive degradation, delaminating of the floor covering from the slab and within itself, condensation, blistering, movement and deterioration of the covering.

Excess moisture can also lead to mold, and mildew as well as the emission of harmful vapors. Most of these problems can be related to the floor covering being installed on a sub floor that is not sufficiently dry.

It is therefore important to insure that the floor slab or screed is sufficiently dry enough to accept a covering.
