CJC4X Suspension Type Methane Detecting Device

General All the performances of the CJC4X intelligent suspension type methane detecting device satisfy the latest national standards AQ6207-2007. The device is a safety instrument adopted for monitoring and over-limit alarming of the gas concentration in the coal mine and other explosive environments; the device is characterized by convenient operation, accuracy and reliability, good stability, easy use and maintenance; it can be carried over by persons or vehicles for patrol inspection, or hung or fixed at a position to monitor automatically; and it is suitable for the work group, upper entry corner, tunneling surface and so on. Thus, the device is a preferred instrument for mass gas monitoring. The most important feature of the device lies in the adoption of black and white components with long service life and high stability, the sensitivity and stability thereof is far superior to that of the currently popular portable gas detector; secondly, the device adopts the 2.3 digital tube with large character and high to that of the currently popular portable gas detector; secondly, the device adopts the 2.3 digital tube with large character and high brightness, and the reading is visual and accurate and can be clearly read within 20 meters. The machine itself is provided with a 3.6V 8000 mAh nickel-metal hydride battery. Another significant feature of the device is that the device can continuously operate for more than 24 hours underground each time when the battery is fully charged. The device has the function of dust protection, shower protection, vibration protection, and electromagnetic interference resistance and automatic sensor protection under the impact of high concentrations gas. All electronic elements thereof adopt the automatic wielding of slice elements, and are treated through rubber after aging, thereby actually realizing zero maintenance.
