Product introduction

The Hero-R5 series of gas detector is a symbol that we HRBEAST have gained the huge turn in gas detection technology. It integrates audible and visual design and will bring in a new revolution for gas detection technology. The design of Hero-R5 has the characteristic of excellent integration, simple installation, convenient operation and portable maintenance. It is the ideal choice for the control of various gas detections or connecting the industry standard PLC.

The Hero-R5 gas detector is consist of combustible and toxic gas detectors with the structure of explosion suppression and the explosion-proof grade of ExdIICT6. It applies to A, B and C grade of hazardous zone II division and the dangerous sites with explosive air mixture I and II division formed by combustible or vapor for the temperature from T1 to T6. It can be widely applied in various oil refineries, chemical plants, and any all other the gas leak places of combustible gas or toxic gas easily release and function long-term and continuous monitoring for these places. when detecting concentration overed the default dangerous concentrations it will sounds more than 80 Db audible alarm and visual alert signals from five directions outside 20 M distance which is the important monitoring instrument to guarantee pepole’s afety and the factory’s security.
