Digital Air Flow Meter One Quarter Inch NPT 0 To 20 Liters Per Minute And 0 To 250 Liters Per Minute Gas Mass Flow Meter With LCD Display Portable Flow Tester For Lab And Shop Floor Use With High Sensitivity And Repeatable Readings

Portable gas flow meter with LCD, 1/4 in NPT
✔️ 0-20 L/min and 0-250 L/min ranges, high sensitivity, single unit

This digital gas flow meter tester measures flows in two ranges: 0-20 L/min (DN 6 mm) and 0-250 L/min (DN 12 mm). It uses a thermal mass flow sensor without temperature or pressure compensation, providing quick, repeatable readings ideal for lab bench testing and shop floor calibration.

✅ Flow range 0-20 L/min (DN 6 mm) for precision testing
✅ Flow range 0-250 L/min (DN 12 mm) for broader tests
✅ LCD display provides clear, real-time readings
✅ Thermal mass flow sensor minimizes drift without extra compensation
✅ Portable design for lab benches and field work

💡 What is a digital gas flow meter used for in lab and shop settings? This handy device helps technicians monitor and calibrate gas flows for accurate testing and process control.

- measure precise flows across 0-20 and 0-250 L/min - quick, readable LCD display for on-site checks - dual-range operation supports both low and high flow tasks
