Alicat MB Series Battery Powered Mass Flow Meters

Performance

Available ranges: max 0-5000 slpm, min 0-0.5 sccm/0-500 sμlm (see Part Numbers tab for stock ranges.)

Flow measurement range: 0.01% – 100% of full scale.

Standard accuracy calibration, NIST-traceable: +/- (0.6% of reading on most instruments.)

Optional high-accuracy calibration, NIST-traceable: +/- (0.5% of reading on most instruments.)

Repeatability: 0.1% of reading + 0.02% of full scale.

Typical measurement response time constant: 5-10 ms.

No warm-up time required.
