product manual


Professional production of fixed, portable, handheld methane detectors, methane concentration detection alarms, methane leak alarms Manufacturer: Shandong Huada Instrument Co., Ltd. Model: HD-700 \ 800 \ 900 Detailed introduction: (TEL: \) Methane The alarm is characterized by high detection accuracy, stable performance, strong anti-poisoning, anti-interference ability, and reliable quality. The methane alarm can work for a long time in the place of flammable and explosive gas. It is used in conjunction with the alarm controller to monitor the gas concentration on site in real time. If the concentration exceeds the standard, an alarm signal will be sent out to eliminate the hidden danger in time.
Each channel of methane leakage alarm is automatically displayed, with LCD backlight, and each channel is automatically inspected, locked, and set. When the concentration of the detected gas in the environment reaches or exceeds the preset alarm value, an audible and visual alarm is issued immediately, and the exhaust air is driven. Cut off and spray the system to prevent occurrence, fire and poisoning accidents, thus ensuring safe production. To remind users to take safety measures!
Methane alarms are widely used in manufacturers of medicine, chemical industry, petroleum, fire protection, electric power, metallurgy, biopharmaceuticals, methane, mines, rare gas research, etc.
【principle】
The detector detects that the gas leakage reaches the set alarm value and outputs a 4-20mA current signal to the alarm host. The alarm host displays the concentration change, and the sound and light alarm, and can link the fan, solenoid valve , exhaust fan and so on.
