NA1000J Gas control panel with temperature & Humidity function

Description

NA1000J gas meter monitor central gas controller with temperature & Humidity function

Brief Introduction:

NA1000J gas control system is an intelligent on-line monitor host developed according to the need to environmental monitor in the process of industrial production. It can detect the content of measured gas in environment by connecting to sensing unit. When the content of measured gas in environment is above-norm, real-time alarm shall be performed. It has the functions of temperature and humidity detection. This system can be extensively applied in petroleum, iron and steel and petrochemical industries, etc.

Main featurers:

1. RS485 bus topology, detection, display, record and alarm of 8 detect points
2. Ultra wide design of working power supply 185~265VAC, preventing surge, anti-attack of thundering design
3. Steady mounting structure, small maintenance
4. It can adopt a centralized bus power supply, also can use independent regional power supply
5. Name, measuring range, resolution and unit of each channel can be modified flexibly
6. Its concentration alarm adopts high and low two levels. It carries out real-time monitoring on combustible gas within the lower explosive limit in industrial environment, and is able to transmit the on-site gas concentration information to the monitoring center at real time.
7. The instrument adopts embedded software design, with powerful function and friendly interface
8. The instrument adoptsembedded software design, with powerful function and friendly interface.
