        Recently, our P series portable gas laminar flow mass flowmeter (hereinafter referred to as the "P series portable flowmeter") passed the calibration test of China Environmental Monitoring Station, selecting five calibration points of 2L/min, 5L/min, 8L/min, 13/min, and 16.785L/min. The average accuracy reached 0.26% and the repeatability was 0.02%, fully possessing the dual traceability ability in the environmental protection industry after passing the type evaluation test of China Academy of Metrology.

       The YIDU P series low pressuer drop portable flowmeter sent for inspection this time is; 0.1~30SLPM  It can be used universally for all particulate matter atmospheric samplers within its range, with a pressuer drop as low as 400Pa, minimizing data errors in converting standard flow rate to operating flow rate, and perfectly matching; The calibration requirement for a volume flow rate of 16.67 liters, with built-in high-precision temperature and pressure sensors, ensures accurate measurement and calibration in any weather environment.
