To ensure your instruments are operating at the proper and ultimate level, an air flow calibrator can be a great asset. New Star Environmental offers the only low flow air flow calibrators that give a direct indication of volumetric flow rate, standard flow rate, barometric pressure (both mm/Hg & mb), ambient temperature, and filter temperature – all in one instrument. With an accessory adapter, the deltaCal is usable with any air sampler in the 1.5 to 19.5 lpm range. Additionally, the tetraCal, which was originally developed as the triCal® for Industrial Hygiene applications, is usable with all types of air samplers in the 0.1 to 30 lpm range.
