Zetron Nitrogen Dioxide Sensor NO2 Sensor 4-Electrode - NO2-B43F

NO2-B43F Nitrogen Dioxide Sensor (NO2 Sensor) Description
Alphasense Nitrogen Dioxide gas sensors operate using proven fuel cell technology.

Sensors are available in the following sizes:
A: 20mm diameter, the industry standard size for portable gas detectors
B: 32mm diameter package, the best choice for fixed site applications
D: miniature, with proven long-term performance. Sensors for the next generation of portable gas detectors

The NO2 range provides OEMs with reliable sensors for use in a number of high volume applications. Strong signal levels combined with low zero current allows resolution to 50 parts per billion (ppb) and an operating range to 20ppm. The sensors are suitable for use in fixed installation sensing heads, portable safety instruments, urban air monitoring and stack gas analysers.

The NO2 sensors offer our electrolyte leak-free guarantee and reliable long-term detection performance. The leakproof housing is moulded with a colour coded top for ease of identification.

NO2-B43F Nitrogen Dioxide Sensor (NO2 Sensor) Features:

1. High resolution up to 20ppb

2. Short response time of 60s

3. Linear output, excellent linearity

4. Interference of O3 gas is filtered

Matched Transmitter board for NO2-B43F NO2 Sensor

Individual Sensor Board (ISB) Alphasense B4 4-Electrode Gas Sensors
The Individual Sensor Board (ISB) is designed for use with the Alphasense B4 family of four-electrode gas sensors. This potentiostat provides a dual channel voltage output.
A low noise bandgap provides the bias voltage for NO sensors and the ISB can measure both oxidising (CO, H2S, SO2 and NO) and reducing (O3 and NO2) gases.
The ISB is configured for specific sensors: NO, NO2, O3 and CO / H2S / SO2 .
Designed for low power applications, the ISB requires 3.5 to 6.4 stable DC supply at only 1mA.
