CD3 multi-parameter gas measuring device

Abstract

The invention provides a CD3 multi-parameter gas measuring device which comprises a machine shell. The upper portion of the front side of the machine shell is provided with a gas chamber window, a sound making hole, a light emitting hole and an alarm lampshade. The middle of the front side of the machine shell is provided with a liquid crystal display screen. The lower portion of the front side of the machine shell is provided with a control button. A gas inlet is formed in the left side face of the machine shell, an emergency lamp is arranged on the upper side face of the machine shell, and the machine shell is internally provided with measuring device function parts including a gas chamber, a circuit main board, a measuring module, an alarm module, a battery and a wireless receiving and transmitting module. The performance of the device is stable, a threshold is accurate, responses are quick, precision is high, the appearance is unique, the size is small, the weight is low and the device is convenient to carry. The humanized design and the soft adjusting technology are adopted, operation is easy, use is convenient, and the machine shell of the measuring device is of an ABS high-strength full-plastic structure. A key type electronic film switch high in sealing performance is used in cooperation, a four-bit high-brightness red nixie tube is used for displaying, a sound, light and vibration combined alarm mode is adopted, alarming is clear and obvious, the alarm effect is more obvious and better, and the wireless receiving and transmitting module is arranged to upload patrolling data.

Description

technical field [0001] The invention relates to a gas detector, in particular to a CD3 multi-parameter gas detector. Background technique [0002] The multi-parameter gas detector is an intrinsically safe instrument that can continuously detect the concentration of toxic, harmful, flammable and explosive gases in the working environment, and can detect the concentration of various toxic, flammable and explosive gases. It is suitable for explosion-proof, poisonous gas leakage rescue, underground pipelines or mines, etc. It can effectively guarantee the life safety of the staff from infringement and the production equipment from loss. It is suitable for detecting the concentration of carbon monoxide in ambient air. Multi-parameter gas analyzers currently in use. Most of them have the disadvantages of poor sensitivity and stability, and short working hours. They are not suitable for mining in mines. At the same time, the detection range of dangerous gases is too small, the ac...

Problems solved by technology

Most of them have the disadvantages of poor sensitivity and stability, and short working hours. They are not suitable for mining in mines. At the same time, the detection range of dangerous gases is too small, the accuracy is not enough, and the alarm system is not perfect, which reduces the safety performance to a certain extent.
