Product Description:
YJJ NO2-B43F 4-Electrode Electrochemical Nitrogen Dioxide Sensor 0-20PPM for Air-Quality Monitor
Features:
I. Product Overview
NO2-B43F is a four-electrode ppb-level high-precision NO₂ (nitrogen dioxide) electrochemical sensor from the Alphasense Alpha B series of the UK. It is commonly installed on the mainboard of gas analyzers (such as the MCX-MPCB1 detection instrument mainboard), and requires a signal processing circuit board to complete current signal amplification, AD acquisition, temperature compensation, and concentration conversion output.
Sensor appearance:
NO2-B43F Sensor
The upgraded model NO2-B43F-IST is equipped with an intelligent temperature compensation board and a storage chip, supporting plug-and-play calibration parameter reading. Table
Project Specification Parameters
Target gas to detect:NO₂ (nitrogen dioxide)
Measurement range: 0 - 20 ppm, supports ppb-level micro-resolution (minimum 20 ppb)
Overload tolerance upper limit: 50 ppm, short-term shock tolerance
Sensitivity: -200 ~ -650 nA/ppm (standard 2 ppm nitrogen dioxide condition)
Recommended load resistance: 33 - 100Ω; preferentially select 33Ω load resistance to ensure low concentration ppb signal resolution
T90 response time: ≤ 80 s (0 - 2 ppm gas step), normal conditions < 60s
Zero point noise: equivalent to ±2 ppb concentration fluctuation
Linear error: 0 - 5 ppm range error ≤ ±0.5 ppb, excellent stability at low concentrations
Design service life / warranty: ≥ 24 months, official two-year warranty period
III. Environmental Adaptation Parameters
Operating temperature: -30℃ ~ +40℃
-20℃ low temperature: sensitivity maintains 60% - 80% at normal temperature (20℃)
40℃ high temperature: sensitivity is within the standard value range of 95% - 115%, temperature drift is controllable
Air pressure: 80 - 120 kPa
Long-term working humidity: 15% - 85% RH (no condensation)
Storage conditions: sealed storage at 3 - 20℃, storage validity period 6 months
IV. Anti-interference (Cross Sensitivity) Parameters
Built-in dedicated ozone filter layer, ozone adsorption capacity > 500 ppm·hr, low interference from common atmospheric impurities is extremely low Table
Interfering gas Testing concentration Interference sensitivity ratio
O₃ Ozone 2 ppm < 500 ppm・hr Filter capacity
NO Nitrogen Oxide 5 ppm < 5 %
SO₂ Sulfur Dioxide 5 ppm < -3 %
CO Carbon Monoxide 5 ppm < -3 %
H₂ Hydrogen Sulfide 5 ppm < -80 %
Hydrogen, Ethylene, Ammonia, Carbon Dioxide Standard testing concentration < 0.1%, almost no interference
V. Hardware requirements for the adapter for the analyzer mainboard (connected to MCX-MPCB1 mainboard)
1. Sensor pin definition (4 electrode pins)
Working electrode WE, reference electrode RE, counting electrode CE, auxiliary electrode AE
2. Essential functions of the mainboard circuit
Sensor bias voltage control, four-electrode constant potential circuit
I/V Current-Voltage Conversion (matching 33Ω load resistor)
High-precision AD Sampling to collect weak nA-level current signals
Temperature compensation algorithm, correcting sensitivity drift in high and low temperature environments
Zero point calibration, range calibration, zero point drift self-check
Concentration value output, over-limit alarm, sensor fault identification
3. Compatible equipment
Portable multi-gas detection instrument (compatible with the MCX-MPCB1 mainboard equipment you have)
Environmental air monitoring equipment, tunnel gas monitoring, industrial exhaust transmitter, atmospheric micro-monitoring station
