TSI 41403 Mass Flow Meter

TSI 41403 Mass Flow Meter

The TSI Nitrous Oxide Mass Flow Meter 41403 (LCD, 0.01-20 L/min / N2O, Air, O2, N2/ 1/4″ tube) can be used for a multitude of gas flow measurement applications. Whether measuring gas flows in a laboratory or manufacturing setting, TSI mass flow meters provide accurate results with multiple data output options. The display versions come complete with accessories making setup and operation fast and convenient.

The TSI Nitrous Oxide Flow Meters are specified as three percent of flow rate reading. One TSI Nitrous Oxide Flow meter covers the same range as three percent (or more) of full scale devices, with better accuracy at most points. Four millisecond response ensures accuracy in fluctuating flows. This fast response time of the TSI mass flow meter is ideal for closed-loop control systems and integrated volume measurements. Low pressure drop of the TSI Nitrous Oxide Flow meter minimizes flow circuit back pressure and its impact on the system.


Range: 0.01-20 L/min. Calibration: N2O, Air, O2, N2. Connections: 1/4 inch tube.
