|product name:||Organic volatiles VOCs gas alarm|
|Measurement object:||Organic volatiles in the air|
Organic volatiles alarm is an instrument used to detect the leakage or concentration of organic volatiles. It can choose to match different parameters according to the same environment. Currently there are two types of PID light particles or electrochemical methods on the market. The principle is to use a gas sensor to detect the organic volatile gas present in the environment. The current signal is converted into readable data and can be output or edited. General organic volatile gas alarms are divided into two types: portable or fixed, also called handheld or online. Different ranges of sensors need to be configured in different environments.
SK-600-VOCs on-line organic volatiles alarm can perform continuous online monitoring for 24 hours, on-site display of concentration and exceeding standard audible and visual alarms, and remote data transmission. According to the different detection gases, the best brands of the current industry in the electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoion principle gas sensor, Swiss high-precision capacitive digital temperature and humidity sensor, SK-600-VOCs advanced circuit The design, mature kernel algorithm processing, obtained a number of software works patents and appearance patents, thus giving birth to the industry's leading new generation of multifunctional fixed-line organic compound gas detection alarms. SK-600-VOCs can detect the gas concentration in pipelines or confined spaces, the atmospheric environment, the gas leakage, and the purity of high-concentration single gases. The sturdy and durable explosion-proof shell and fluorocarbon paint surface treatment process are suitable for various hazardous locations and corrosive environments with strong acids and alkalis.

Selection of concentration measurement range of measuring instruments:
Various types of toxic and harmful gas detectors have their fixed detection ranges. Only when the measurement is completed within its measurement range can the instrument accurately measure. If the measurement is performed beyond the measurement range for a long time, it may cause permanent damage to the sensor. For example, if the LEL detector is accidentally used in an environment with more than 100% LEL, it may burn the sensor completely. Toxic gas detectors can also cause damage if used for a long time at higher concentrations.
In short, the toxic and harmful gas alarm is a powerful tool to ensure industrial safety and health of workers. We should choose the appropriate gas alarm according to the specific use environment and the required function. At present, the alarms that we can choose from include fixed / portable, diffusion / pumping, single gas / multi gas, inorganic gas / organic gas and many other combinations. Only by choosing the right gas alarm can you really do more with less and prevent trouble before it happens.
