CRH measuring chamber CRH100
For quick and safe testing of the readiness for covering of mineral screeds according to the CRH method
The CRH measuring chamber from Trotec enables both a simple and informative residual moisture measurement in mineral screeds for testing the readiness for covering according to the CRH method – certified by the TKB (Technical Commission on Construction Adhesives of the German Adhesives Industry Association).
The CRH100 was specially developed to be used in combination with the Multifunction measuring meter T3000 and the connected Climate sensor TS 230 SDI but is in general also suitable for sensors of any other brand, provided their diameter is 12 mm.
Optimal device combination for CRH measurements
The CHR method is a simplified and user-friendly alternative method for testing the readiness of mineral-bound screeds for covering. By means of the CRH method, the corresponding relative humidity (CRH) of a mortar sample can be determined and serve as a reliable indicator for the moisture condition of screeds before covering.
Compared to other measuring methods for testing the readiness for covering, the CRH method via T3000 with TS 230 SDI and measuring chamber CRH100 offers numerous advantages. For example, meaningful results can be obtained even if the material type of the screed is unknown. Besides, no exact material weights are required for the CRH method which is why measurement errors due to weighing errors cannot occur. Furthermore, using additional chemical substances such as calcium carbide ampoules is not necessary.
Time-saving test procedure for determining the readiness for covering with the CRH measuring chamber CRH100
By using multiple CRH100 devices, users can benefit from a significant advantage in time when testing the readiness for covering. If, for example, three samples need to be taken, they can each be filled separately into one of three CRH100 devices, which can then be sealed climate-proof by means of the sealing plug supplied. The corresponding relative humidity of all samples can then be measured one after the other. Alternatively, taking samples and measurements can be performed in one go, i.e. take the sample and fill the CRH100, start the measurement, start the second sample at the same time and so on. In any case, there is a significant gain in time compared to other methods!
The CRH measuring chamber CRH100 provides quick and easy measurement operations for testing the readiness for covering:
