JWGas-CDF(Z17) High Range CO2 Sensor is a digital carbon dioxide sensor designed for measuring high CO2 concentrations in air or nitrogen. Based on thermal conductivity sensing technology and an integrated Sensirion STC31-C CO2 sensor, it provides a measurement range up to 0–100 vol% with temperature and humidity compensation.
With optional RS485 Modbus RTU or SDI-12 V1.3 output, low power operation, wall-mounted installation, and integrated temperature, humidity, and dew point measurement, this high concentration CO2 sensor is suitable for cold chain logistics, storage monitoring, laboratory gas measurement, environmental monitoring, and IoT-based gas monitoring systems.
2. Product Overview
JWGas-CDF(Z17) High Range CO2 Sensor is designed for high concentration carbon dioxide measurement where ordinary low-range CO2 sensors are not suitable. It can measure CO2 concentration in air or nitrogen with a range up to 100 vol%, making it suitable for storage rooms, cold chain logistics, laboratories, controlled gas environments, and industrial environmental monitoring.
The sensor integrates CO2, temperature, humidity, and dew point measurement in one compact wall-mounted device. It supports SDI-12 and RS485 Modbus RTU, allowing easy integration with data loggers, IoT gateways, PLC systems, environmental monitoring platforms, and remote gas monitoring networks.
According to the supplier manual, the sensor supports 5–28 V DC power input, IP50 protection, wall-mounted installation, default 2 m cable, and a compact sensor body size of 111 × 25.5 mm.

FAQ
Q
1. What does the JWGas CDF High Range CO2 Sensor measure?
A
JWGas-CDF(Z17) sensor measures high concentration carbon dioxide from 0 to 100 vol%, along with temperature, humidity, and dew point.
Q
2. Is this sensor suitable for normal indoor CO2 monitoring?
A
It can measure CO2, but it is mainly designed for high concentration CO2 applications. For typical indoor air quality monitoring around 400–5000 ppm, a lower-range CO2 sensor may be more suitable.
Q
3. Can JWGas-CDF(Z17) measure CO2 in nitrogen?
A
Yes. JWGas-CDF(Z17) supports CO2 measurement in nitrogen and air. Users should select the correct gas type setting before use to improve measurement accuracy.
Q
4. Does JWGas-CDF(Z17) support RS485 Modbus RTU?
A
Yes. JWGas-CDF(Z17) supports RS485 Modbus RTU, making it suitable for PLC systems, industrial IoT gateways, data acquisition units, and cloud monitoring platforms.
Q
5. Can JWGas-CDF(Z17) work with SDI-12 data loggers?
A
Yes. JWGas-CDF(Z17) supports SDI-12 V1.3, making it suitable for data loggers, remote environmental monitoring stations, and low-power field monitoring systems.
Q
6. What is the CO2 measurement resolution?
A
The CO2 resolution is 0.01 vol%, suitable for high concentration gas monitoring applications.
Q
7. Does the sensor support calibration?
A
Yes. JWGas-CDF(Z17) supports automatic calibration and forced calibration. Forced calibration should be performed in a known, uniform, and stable CO2 concentration environment.
Q
8. What is the response time of the CO2 measurement?
A
The response time is 0.5 seconds without filtering. Stronger filtering can provide smoother data but will slow down the response.
Q
9. Does JWGas-CDF(Z17) measure temperature and humidity?
A
Yes. JWGas-CDF(Z17) measures temperature, humidity, and dew point in addition to CO2 concentration.
Q
10. Is JWGas-CDF(Z17) suitable for battery-powered systems?
A
Yes. The SDI-12 request measurement mode has a static current of less than 50 μA at 12 V DC, making it suitable for low-power monitoring applications.
Q
11. What applications is this sensor best suited for?
A
It is suitable for high concentration CO2 detection, cold chain logistics, warehouse monitoring, controlled atmosphere storage, laboratory gas measurement, environmental monitoring, and industrial gas monitoring.
Q
12. Does JWGas-CDF(Z17) support OEM or ODM customization?
A
Yes. JWGas-CDF(Z17) supports OEM and ODM customization, including communication interface, cable length, labeling, gas type configuration, and system integration requirements.
