Product Description
Product Introduction
This equipment is a new type of highest grade gas flow standard device.The measuring range is from 0.003L/min to 666L/min, and the accuracy is better than bell jar and sonic nozzle gas flow standard device.It has the advantages of high accuracy, wide range of flow and pressure, fast measuring speed and high automatic control efficiency.It is suitable for research and development, experiment, verification, type evaluation, quantity value transmission and tracing of gas flowmeter.
Product Features
1. Measurement performance is equivalent to the national benchmark.
2. High accuracy of temperature and pressure measurement.
3. Piston stroke precision measurement.
4. Wide range of flow and pressure, stable output.
5. Multi-stage seal, no leakage, self-lubrication.
6. Multiple protection, safe use.
7. Automatic measurement and control, bus real-time high-speed transmission of measured values.
8. Small space, easy to move.
