Introduction: Odor refers to all gaseous substances that stimulate the human olfactory organs, cause unpleasantness and damage the living environment. So far, there are more than 4,000 kinds of odorous substances that can be sensed by the human sense of smell, of which there are dozens of kinds that are more harmful to human health. Some exude the smell of rotten stinky fish, such as amines; some are pungent, such as ammonia and aldehydes; some exude the smell of rotten eggs, such as hydrogen sulfide; The foul-smelling substances make people short of breath, nausea and vomiting, irritability, dizziness, and even suffocating people. JK50-OU fixed on-line odor gas detection and alarm instrument is based on China's current odor detection standards "odor pollutant emission standard GB14554-93" and "three-point comparison odor bag method GB/T 14675-93" to achieve detection results and human sense of smell It is a odor analyzer independently developed and produced by Jishun'an patented technology and independent algorithm, commonly known as the odor electronic nose. It can simultaneously monitor various indicators of odorous substances including odors (odorous gas, trimethylamine, hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide) specified in the "Emission Standard of Odor Pollutants (GB14554-1993") , carbon disulfide, styrene, odor), optional parameters such as PM2.5, PM10, temperature, humidity, wind speed, wind direction, atmospheric pressure, illumination, noise, etc. Features: 1. Intrinsically safe circuit design, explosion-proof certification, secondary lightning protection, anti-static, lightning protection and anti-static capabilities exceeding the standard, resistance to strong pulse surge current impact. reliability and stability. Anti-reverse connection design, any form of reverse connection will not damage the instrument 2. Compliant with EMI and EMC standards, passed the standard test and CMC measuring instrument license certification. 3. Standard bus RS485 (RTU) and 4-20mA standard signal output at the same time, 3 groups of relay switch output, on-site sound and light alarm (optional). 4. Compatible with various secondary meters, data acquisition modules, PLC, DCS systems, can directly drive equipment such as solenoid valves, fans, alarms, etc., and can also drive high-power equipment by driving intermediate relays. Optional MIC2000 controller can monitor 1000 detectors at the same time. 5. Large-capacity data storage function, can record real-time concentration value, temperature and humidity, or only record alarm value and time. Support local storage or SD card storage, the standard storage capacity of this machine is 100,000 records, please specify when ordering a larger capacity. 6. Standard infrared remote control, which can realize operation without opening the cover in dangerous occasions. 7. Chinese and English interface can be selected, the default Chinese interface, supports free switching of gas concentration units, conventional gas does not need to input molecular weight, special gas input molecular weight is automatically calculated and switched, optional units: PPM, mg/m3, Vol%, LEL %, PPHM, ppb, mg/L 8. Three display modes can be switched: simultaneous display of multiple gas concentrations, circular display of single-channel gas concentrations in large fonts, real-time curves, automatic or manual cycle switching between channels, and whether to display large, small, and gas name to view the history graph. 9. Automatically track the zero point to prevent drift, temperature compensation, multi-calibration, and can meet the standard and local and provincial standards of measurement bureaus in various regions at the same time 10. The data recovery function and the concentration calibration misoperation can be automatically identified and prevented, which can avoid the failure caused by improper operation. 11. It can record calibration log, maintenance log, fault solution countermeasures, sensor life expiration reminder, and next concentration calibration time reminder Technical parameter: Detection gas: malodorous gas Detection principle: electrochemistry, MOS, PID, catalytic combustion, Bluetooth, semiconductor, etc., depending on the gas type, range, site environment and user needs.
