The mini-BUCK™ Model M-5
Product Description

Flow range: 1 - 6000 cc/min

Primary Flow Calibrator is the industry standard for day-to-day flow verification and calibration of your personal and environmental sampling pumps. It is also suitable for verifying rotameters, setting instrument panels, and calibrating laboratory instruments. No more lugging oversized calibration panels. No more rotameter inaccuracies. The mini-BUCK™ is accurate at any altitude and can be used for flow measurements with sampling media. Rugged design provides fast, one-handed operation with an easy-to-read LED display visible even in sunlight. Flow cells are sun shielded, with a sealed bubble stem for pressure readings, easy to clean, won’t leak even if unit is inverted. The mini-BUCK™ automatically displays averaged readings of volumetric flow and is NIST traceable with display accuracy of ± 0.5%

The first electronic gas flow standard,
NIST traceable with accuracy of ± 0.5%
