Environmental & Water Quality Sensors
GZ04Gas Monitoring
CO2, Temperature & Humidity Transmitter
Measures CO2 concentration, temperature, and humidity with an infrared CO2 sensor. Default CO2 range is 0–5000 ppm (0–10000 ppm optional) with accuracy ±(50 ppm + 3% F·S) at 25 °C and RS485 Modbus-RTU output; suitable for agricultural greenhouses, flower cultivation, and edible fungus cultivation.
- CO2 Accuracy
- ±(50 ppm + 3% F·S) (25 °C); ±(50 ppm + 5% F·S) for optional range
- CO2 Measuring Range
- 0–5000 ppm (default); 0–10000 ppm (optional)
- Output
- RS485, standard ModBus-RTU
- Power Supply
- 10–30 VDC
- Infrared calibration for CO2 measurement with high accuracy, low drift, long life
- Wide measuring range 0-5000 ppm default, optional 0-10000 ppm, with temperature compensation
- RS485 communication, standard ModBus-RTU, address and baud rate settable, up to 2000 m
- Wall-mounted waterproof shell, easy to install, high degree of protection
- 10-30V wide-voltage power supply with average current <85mA
- Data update time 2 s; response time less than 90 s at 90% step change

GZ04 questions
What ranges are available for the GZ04?
Standard coverage is 0–5000 ppm (default); 0–10000 ppm (optional). Other spans, outputs, and process connections can be sourced to match the application. Send the working pressure and medium and we will confirm the exact option.
What is the MOQ and lead time?
1 pc (flexible, no minimum for most products). 2-3 days for in-stock items, 15-30 days for custom orders. Samples are available, with freight on the buyer’s account.
Can the GZ04 be customized?
Range, output signal, process connection, cable length customizable through our supply partners.
Do you manufacture this transmitter?
SIBXSUN is an industrial instrumentation supplier in Ningbo, not the factory. We source the GZ04 from qualified partners, inspect before shipment, and handle export documents and logistics.
Need the right co2, temperature & humidity transmitter for your process?
Send the medium, range, output, and quantity. We will confirm the matching option and a FOB Ningbo quote.
