How it works: FP-25 field flow calibrator for PM air samplers
FP-25 field flow calibrator for PM air samplers Alicat’s FP-25 and FP-25BT flow devices can be used to calibrate any low-volume particulate air sampler on your deck. These NIST- traceable field flow calibration devices are multi-parameter mass flow meters that display pressure and temperature. The FP-25 uses multiple pressure sensors to capture both ambient barometric […]
