The product meets GB 3095-2012 ambient air quality standard; HJ 654-2013 technical requirements and detection methods for continuous automatic monitoring system of ambient air gaseous pollutants (SO 2, no 2, O 3, CO).
The instrument adopts touch type 7-inch color screen and full Chinese menu operation interface. Touch control simplifies the operation procedure, and the flow of mass flow controller is controlled by microprocessor.
Chinese and English menu operation interface and operating system.
The digital mass flowmeter is used to ensure the accuracy, stability and repeatability of the gas distribution flow.
It has multi parameter alarm function.
It has the function of temperature and pressure automatic compensation.
All valves and joints are made of PTFE or PVDF to reduce the impact on concentration.
A large number of dry, high purity and stable zero gas sources are provided outside the ozone calibration system.
External high stability integrated ozone generator is provided to ensure the stability of ozone supply.
The ozone calibration system provides a unified high-precision UV photometer.
Th-2003bz (SRP) primary ozone calibration system mainly includes SRP host, zero gas supply system, high-precision pressure sensor, system workstation, SRP and ozone analyzer module, laboratory ventilation and ancillary facilities. SRP host consists of internal ozone generator or external ozone generation system, zero gas generator system, ultraviolet photometer and control system (computer data acquisition and control).
