The product meets the technical requirements and testing methods of orifice flowmeter used for calibrating total suspension sampler in HJ / t368-2007, and implements the enterprise standard Q / wth37-2017: enterprise standard of THM series microcomputer flow calibrator.
The thm-1200 (150) micro-computer flow calibrator is suitable for the flow calibration of various large (medium) flow total suspended particle sampler. The measuring principle is to use micro differential pressure sensor to detect the orifice pressure difference. The microcomputer program control and automatic data processing can display the flow, volume, temperature and pressure under working conditions and standard conditions, and can store 5000 groups of data circularly. The instrument is easy to operate and carry.
