Product Details
3NFF 3NF/F Electrochemical Nitrix Oxide NO Gas Sensor For Both
Fixed And Portable Gas Detection Equipment
Key Features:
- Anti-interference Filter: Equipped with an inboard filter that
removes the interfering effect of SO₂ in the flue stream, which is
critical for ensuring measurement accuracy in flue gas analysis
scenarios where SO₂ often coexists.
- Stable and Reliable Performance: It has low long-term output drift
(less than 2% signal loss per month) and excellent repeatability
(2% of signal). Meanwhile, the maximum zero shift is limited to 30
ppm equivalent within the 20°C - 40°C range, guaranteeing
consistent data output over long-term use.
- Broad Environmental Adaptability: It can work normally in a
temperature range of -20°C to +40°C and a non-condensing humidity
range of 15% - 90% RH. Its tolerance to slight atmospheric pressure
fluctuations (±10%) also allows it to be used in most indoor and
outdoor environments.
- Easy Integration: With clear requirements for bias voltage (+300
mV) and load resistor (10 Ω), the sensor has a simple electrical
interface. It can be easily integrated into various gas detection
devices and analytical instruments without complex circuit design.
Typical Applications:
- Flue Gas Analysis: It is especially suitable for NO content
detection in flue gas, and can be used in conjunction with sensors
such as 3SF/F and 2FO to form a complete flue gas analysis solution
for industrial boilers and incineration equipment.
- Industrial Safety Monitoring: Deployed in factories or workshops
that generate NO during production processes, to monitor toxic gas
concentrations in real time and protect the health of on-site
workers.
- Environmental Monitoring Equipment: Integrated into portable or
fixed environmental detectors to monitor NO emissions from
automobile exhausts and industrial waste gas, supporting
environmental pollution control work.
- Special Gas Detection Systems: Applied in customized gas analysis
equipment for research institutions and laboratories, used for
precise measurement of NO in experimental environments.
