CD4 multi-parameter gas detector manufacturer

>D Multi-gas Detector
The multi-parameter gas detector can alarm over limits. When the concentration of the gas to be measured reaches or exceeds or falls below the preset alarm value, the detector will immediately send out an audible and visual alarm. .
Specific technical indicators of multi-parameter gas detector
Measurement gas: methane, oxygen, carbon monoxide, hydrogen sulfide Measurement principle: catalytic combustion sensor electrochemical sensor (,, H)
Measurement method: diffusion Type measurement method alarm point setting: full range adjustable measurement range: H: ~.% H: ~.%: ~H: ~ Measurement accuracy: H: +%: +.%: +% H: +% Resolution: H: .%H: .%: H: Indication mode: D displays real-time data and system status, audible and visual alarms, fault and undervoltage indications.
The sound level intensity of the instrument should not be less than 1 meter away from the buzzer. The visibility of dB light signal in the dark is not less than 1 meter.
The intrinsically safe power supply of the measuring instrument: mH polymer lithium battery. The battery is protected by a protective plate and has over-current protection function.
Charging time: h shutdown current is less than.
Working time: h (non-alarm status)
