The mini-BUCK 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 instrumentation. No more lugging oversized calibration panels. No more rotameter inaccuracies. The mini-BUCK is accurate at any altitude. 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%. Several flow ranges available.

• Primary flow standard, NIST traceable with display accuracy of ±0.5%
• Instant readout of volumetric flow rate for either vacuum or pressure pumps
• Wide choice of flow ranges: M-1 0.1-300 cc/min, M-5 1-6000 cc/min, M-30 100 cc/min-30 LPM
• Works at any altitude without correction and is resistant to temperature changes
• Microprocessor controlled for fast, accurate, repeatable one-button measurements
• Rechargeable, replaceable battery pack rated for 8 hours of continuous use
• Compact, lightweight design with a sunlight-readable LED display; Certificate of Calibration shipped with each unit
