R Practical Fixed Combustible Gas Detection Alarm
Product Overview
R is a high-performance practical combustible gas detection alarm developed by our company. It adopts high performance and low power consumption. The advanced microprocessor ensures the performance and stability of the product and can monitor the concentration of combustible gases in real time. Mainly used in petrochemical industry, metallurgy, mining, fire protection, gas, environmental protection, electricity, communications, paper printing and dyeing, grain reserves, urban water supply, sewage treatment, food brewing, scientific research, education, national defense and other places.
Two main features

There are three signal outputs: R and ~ (three-wire digital/analog signals and switch values) at the same time.
The large screen segment code type displays the gas concentration in real time.< br /> Gas concentration units are optional (for example, /, with instrument status, fault and communication abnormality prompt functions.
High and low alarm points can be set, and two-level sound and light alarms.
Two-way relays can control peripherals Equipment (such as fans and sound and light alarms).
The round die-cast stainless steel shell is suitable for use on offshore platforms and in harsh environments such as high temperature and humidity.
It has good sealing, anti-corrosion, and explosion-proof And resistance, R function.
Can be used with the R series alarm host produced by our company.
European design standards.
