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.
