Air flow calibrators are used to calibrate the air flow rate through personal sampling pumps and other general air sampling equipment.
Offering fast, ±1% of reading calibrations the Defender Series has three levels of instrumentation, providing flexibility in applications. The Defender 510 is a volumetric primary flow standard. The Defender 520 is an enhanced volumetric primary flow standard that also records ambient temperature and pressure conditions, while the Defender 530 is a volumetric primary flow standard that standardizes readings automatically.
Sampling pumps have a broad dynamic flow range with a choice of single, hands-free continuous, or user-specified “burst” measurements. Time intervals between measurements allow for checking personal sampling pump stability over a typical sampling period. The unit is a field-friendly, rugged and lightweight design featuring a large, illuminated liquid crystal display and intuitive menu navigation. Compliant with RoHS and CE standards. Volumetric accuracy is ±1%, and volumetric options are mL/min, L/min, cc/min, and cf/min. New Star Environmental
