Product Introduction

1. Description of Nitrogen Dioxide Sensor (NO2 Sensor) 4-Electrode NO2-B43F NO2-B43F+:

The NO2-B43F sensor is a PPB sensor designed for ambient air quality applications with excellent baseline stability. It is available in our standard format (NO2-B43F) and with our patented integrated smart technology (NO2-B43F+), which integrates an IST board with memory chip and temperature sensor into the sensor. The + version stores specific calibration, specification, and identification data on each sensor, allowing plug-and-play operation. The onboard temperature sensor improves the accuracy and ease of temperature compensation algorithms.

9. Matching Sensor Board for High-Resolution Nitrogen Dioxide Sensor (NO2 Sensor) NO2-B43F:

Unique Sensor Board (ISB) Alphasense B4 4-Electrode Gas Sensor - ISB

This unique sensor board (ISB) is used for Alphasense B4 series 4-electrode gas sensors. The regulator provides dual-channel voltage output.

The low-noise bandgap provides bias voltage to NO sensors, while the ISB can measure oxidizing (CO, H2S, SO2, and NO) and reducing (O3 and NO2) gases.

The ISB is configured in four versions for specific sensors: NO, NO2, O3, and CO/H2S/SO2.
