Portable Gas Detectors can detect VOC, Toxic, Combustible & Oxygen types of gases which are used for personal safety. Portable Gas Detection System will detect the concentration of gases in confined spaces, sewer manholes, wastewater treatment plants, pharmaceutical industries, fertilizer industry, and many other applications with the display of gas concentration on the LCD. Portable Gas Monitors are a must for people entering hazardous areas. These detectors have the feature of secure handling and programming with three keys and power supply with rechargeable batteries. They have a password-protected function menu, plug-in sensor, and built-in audio buzzer. These Portable Gas Detectors also have optional data logging facilities with 50000 records, which are visible in ASCII format while downloading to PC via USB interface.

Introduction: QB2000 gas alarm control panel is a multi-point monitoring of the latest design with simple operation and it combines with any gas detectors to form an industrial gas detection system. This control panel embeds micro processor as control unit, when the detected gas density in the air reaches or exceeds the pre-set value, the controller will give out audio-visual alarm immediately to remind you take safety precautions and alert the corresponding valve, exhauster and other equipment to avoid explosion, fire, toxic gases to protect the safety of life and treasures. This system applies to metallurgy, petrol, petrifaction, chemistry, light industry, coking, municipal administration, gas, pharmaceutical, sewage dealing and many other special industry and field that need proofing for fire, explosion, and toxic gas leakage. Characteristics: High-performance sensor 128*64 dot matrix big screen liquid digital display With English Instruction Manual and pictures easy to operate Various gas detector together to fix Display the detected gas density in distance High sensitivity, and quick response Automatic compensation for temperature -drift and time drift The up and low alarm points of each channels can be set separately 8 channel 4-20mA signals output RS485, RS232 communication port can upload data to computers & 4 Relay output and the relay setting is programmable
