7HCN-50 Gas Sensor Hydrogen Cyanide For Medical Gas Detection
Usage:
Industrial Safety Monitoring: Hydrogen cyanide is a highly toxic gas. The 7HCN - 50 gas sensor is mainly used to detect the concentration of hydrogen cyanide gas in industrial production environments, such as chemical plants, electroplating workshops, and some metal - processing factories. It can timely alarm the leakage of hydrogen cyanide gas, protect the safety of workers, and ensure the normal operation of production equipment.
Medical Gas Detection: It can be applied to some medical gas detection equipment. Although hydrogen cyanide is a toxic gas, in some medical research or special treatment scenarios, monitoring the concentration of trace hydrogen cyanide gas may be involved, and this sensor can play a role in related detection.
Fire Safety Detection: In the process of fire, some organic substances will decompose and produce hydrogen cyanide gas. The 7HCN - 50 sensor can be used in fire - fighting equipment or fire - safety monitoring systems to detect the presence and concentration of hydrogen cyanide gas, providing important information for fire - fighting and rescue operations and ensuring the safety of firefighters.
Features:
High - precision Measurement: With a resolution of 0.2 ppm, it can accurately detect low - concentration hydrogen cyanide gas, and the linearity can reach up to 50 ppm, which provides reliable data support for accurate measurement.
Fast Response: The response time (T90) is ≤ 120 s, which can quickly sense the change of hydrogen cyanide gas concentration. Once the gas concentration in the environment changes, it can quickly output a corresponding signal, facilitating timely monitoring and early warning.
Good Environmental Adaptability: It can work normally in the temperature range of - 20℃ ~ 50℃ and the humidity range of 15% ~ 90% RH (non - condensing), with strong adaptability to different environmental conditions, and can be applied to a variety of complex working environments.
Long Service Life: The expected operating life in clean air is 2 years, and the storage life in the original packaging is 6 months, which has good durability and stability, reducing the frequency of sensor replacement and use costs.
High Overload Resistance: It can withstand an overload of 100 ppm hydrogen cyanide gas. When the gas concentration briefly exceeds the measurement range, the sensor is not easy to be damaged, and the performance is relatively stable.
Good Selectivity: It has little cross - sensitivity to common gases such as carbon monoxide, sulfur dioxide, and nitrogen dioxide, which can effectively avoid false alarms caused by other gases and ensure the accuracy of measurement results.
