4CJYB4/25 Methane Oxygen Two Parameter Alarm DeviceAlarm point:
(1) The alarm sound level intensity should not be less than 75dB (A);
(2) The alarm light signal should be clearly visible at a distance of 20m in the dark, with a color of red.
(3) Oxygen: It can be set arbitrarily within the range of 18.0% to 20.0% O2. The factory default setting is 18.0% O2, and the alarm error should not exceed 0.3% O2.
(4) Methane: It can be set arbitrarily within the range of 0.50% CH4 to 2.50% CH4. The default setting at the factory is 1.00%, and the alarm error should not exceed the set value ± 0.05% CH4.

(2) Methane: 0.01% CH4.
7CJYB4/25 Methane Oxygen Two Parameter Alarm DevicePower supply: It consists of a YT-103450-1.8Ah lithium battery, connected in series with a 1.4 Ω/16W current limiting resistor, and encapsulated with epoxy resin to form an intrinsic safety battery module; Rated voltage Ue: 3.7V, output voltage Uo: 4.2V, output current Io: 2.33A.
Continuous working time after charging: ≥ 10h.
Under voltage indication: When the battery voltage is below 3.30V, the buzzer periodically emits a "beep beep" sound prompt. When the battery voltage is below 3.10V, the instrument automatically shuts down and needs to be charged before use.
Sensor lifespan: Carrier catalytic element: MJC4/2.8J type, lifespan ≥ 1 year; The lifespan of electrochemical oxygen sensors is ≥ 2 years.
