29/1/2021· The first step is to understand the sensor a little. Winsen ZE25O3 is a fairly cheap sensor (around 33USD or 28EUR over at aliexpress). It is an electrochemical sensor, which means that it reacts with the target gas, which is ozone in our case, resulting …
Reliable gas sensors with a variety of gases detected: Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Ozone (O3), Sulfur Dioxide (SO2) mainly usable for ambient environmental monitoring having a high correlation with air monitoring stations. AQ3 gas sensors are designed for operation in a wide range of environments and harsh conditions.
O 3 + NO 2 realtime monitoring. Very high sensitivity to capture low level gas concentrations (down to ppb) Accurate measurement data at a fraction of the cost of Reference Analyzers. No maintenance and no need for recalibration (1 year lifetime) Embedded USB and UART / ModBus communication ports.
Gas concentrations for both O3 and NO2 are typically 20 to 200 ppb at the roadside, so good design of the sensor, housing and electronics plus intelligent data analysis are all required. The B series sensors are designed for use in urban air fixed site networks while the A series sensors are designed for portable use and indoor air quality networks.

It offers high sensitivity for ppb detection, with resolution of 10ppb when used with recommended circuitry. There is also a precalibrated module option available. AQ3OZ Sensor only: Ozone O3 Gas Sensor, 4electrode, 3 series size, highly sensitive for ppb detection, 01ppm O3 (5ppm O3 overrange).
Weight: 13g. OXB431 feature introduction: The British Alphasense highresolution ozone sensor (O3 sensor) OXB431 can simultaneously detect O3 and NO2 (the signal magnitude of the two gases is equivalent). In the mixed gas, in order to accurately detect the O3 content, it is necessary to use NO2 which can only measure NO2.
24/4/2020· GAS SENSOR: Range: 04 ppm (4 000 ppb) Accuracy: at: 20°C (% output at 20°C/output at 20°C) at 2ppm O3 60 to 80, at: 40°C (% output at 40°C/output at 20°C) at 2ppm O3 80 to 105. Measurement interval: 1 minute to 10 days, configurable. Memory size: 60 000 measurements. TEMPERATURE SENSOR: Range: 35° to 70°C
Flowcell for Dissolved O3 / pH Combo system should be kept within 25’ for monitor. Q45H/64 Features Wide Detection Ranges User Settable ranges from 0200 PPB up to 0200 PPM provide maximum application flexibility.
The 2B Technologies Model 202 Ozone Monitor™ is designed to enable accurate and precise measurements of ozone ranging from low ppb (precision of ~ ppb) up to 250,000 ppb (0250 ppm) based on the wellestablished technique of absorption of UV light at 254 nm. Flash card memory and a quiet, longlife internal air pump are now provided ...
