Mini-Buck - Model M-30B - Primary Flow Calibrator - Brochure

The Primary Flow mini-BUCK Calibrator model M-30B is an industry first for day-to-day flow verification and calibration of your microbial air sampling pumps which require 1/2” hoses to minimize backpressure. The M30B, a modified version of our standard M-30 mini-BUCK Calibrator will only measure vacuum flow; no positive pressure can be measured with this model. The rugged design provides fast, one-handed operation with an easy-to-read LED display visible even in sunlight. The mini-BUCK Calibrator model M-30B automatically displays averaged readings of volumetric flow and is NIST traceale with a display accuracy of ± 0.5%.
