Standard-Kit

Air Change Rate (ACR) measurements using the Standard Kit can also be done from unexperienced clients if they follow the instructions carefully. The Standard Kit contains one injection syringe (syringe filled with diluted SF6 in N2 for room volumes <300 m³ or pure SF6 in N2 für Raumvolumina <300 m³ oder mit reinem sf6 6 for room volumes between 300 - 3000m³) and 5 empty syringes for sampling, instructions and a protocol form to note the required boundary condistions of the test. For more information see 'Downloads'.

Combi-Kit

The Combi-Kit is a cost effective way to measure two ACR in one zone under different ventilation regimes. After injection 5 samples are taken for ventilation regime 1. Then the ventilation regime is changed and 5 further samples are taken. More in the 'Download' section.

SF6 and PFT analyses

As a service TRACERTECH analyses tracer gas samples which have been drawn by clients. For SF6 and specified Perfluorocarbon tracer multiple calibration gases exist from low ppt up to 100ppb range to guarantee a precise analysis. The following tracer gases can be analysed: SF6, PMCP, PMCH, m-PDMCH and PFMD.

ASTM Kit

The ASTM Kit is recommended for consultants and law suits. This test is in conformity with the standards (EN ISO 12569 and ASTM 741). In addition to the Standard- and Combi-Kit procedure it is required to take local samples before and after the nominal ACR test to confirm complete mixing. The local concentration differences must not be higher than 10% of the mean. Also the minimum time interval between samples is defined.
