Portable digital gas flow meter tester with digital display (MF5712 (0-250 l/min))

The MF5706 (0-20 l/min) / MF5708 (0-100 l/min) / MF5712 (0-250 l/min) flow meters are suitable for instantaneous flow testing and flow accumulation calculations for various gases such as air, compressed air, oxygen, nitrogen, CO₂, and other inert gases. They offer high stability, high accuracy, and excellent repeatability across the entire range. The detection chip uses thermal mass flow measurement, eliminating temperature and pressure compensation to ensure high-precision flow meter readings. High sensitivity allows measurement to begin even at very low flow rates. A single chip integrates multiple sensors, resulting in a range ratio of 80:1 or higher. They support the measurement of multiple gases, enabling customers to calibrate specific gases on-site. Fast response time. Flexible output mode, LCD screen, RS485 communication interface can also be provided for querying output data via the host computer. Portable design; battery and external power supply can be switched as needed. G thread or NPT threaded connection, easy to install and use; other interfaces can also be customized according to customer requirements.
