EST-101-H2S hydrogen sulfide detector is a portable gas concentration measuring instrument. It adopts high-precision circuit design. The core adopts imported sensor chip. After Wanji Technology develops calibration, signal amplification, calibration calibration and strict testing, it is delivered to the factory.
The instrument is designed and produced in accordance with relevant national standards:
GB/T18883-2002
GB3095-1996
GB50325-2010
GB50325-2001
GB12358-2006
Mainly used:
Disease control medical public places, occupational health and health testing
Natural gas, liquefied gas application place
Coal mine
Petrochemical
Indoor air quality testing agency
Features:
High quality sensor for stable and reliable performance.
External power supply DC5V, built-in rechargeable battery.
Intelligent design, automatic detection at startup, no operation, zero calibration is convenient.
It has the function of restoring factory settings to prevent misoperation.
Supports ppm and mg/m3 unit conversion.
Configuration method LCD liquid crystal display technology, can display gas type, unit, concentration value, 1 hour and 8 hour average, date and time.
The instrument has a weighted concentration value viewing function for 1 hour, 8 hours, and time period, which is in line with the national indoor air quality testing standard.
With alarm function, it can set high and low alarm value, two-level sound and light alarm, and two high-brightness LED lights remind users to pay attention when alarming.
The instrument is small and light, and can be easily placed in a pocket or bag.
ISO9001 quality certification, ISO14001 environmental system certification, can pass the national measurement certification.
Optional sampling pump for safe measurement of closed spaces such as pipes, tunnels and test chambers.
