A hand-held calibrator developed to enable the fast, accurate calibration of high volume air samplers has been introduced by Quantitech. The TCR Tecora Flowcal is traceable to UKAS?standards and can be used to check the performance of air samplers such as the ECHO ambient air particulate sampler. The calibrator can operate either of two flow cells:?a Hi Flow cell with a range of 150-600l/min and a Mid Flow cell, with a range of 10-60l/min.

Quantitech’s Dominic Duggan, said: “…the unit’s screen commands guide users through the process, storing data for subsequent transfer to PC. As a result it is possible to perform a traceable calibration on any air sampler, in the field and in just a few minutes.”
