GZ05Gas Monitoring
Digital Carbon Dioxide Sensor
This digital carbon dioxide sensor measures CO2, air temperature, and humidity using photoacoustic NDIR sensing. It offers a CO2 range of 0–5000 ppm with accuracy from ±(50 ppm + 2.5% reading) depending on range, and outputs via SDI-12 or RS485 Modbus-RTU. Typical applications include smart agriculture, greenhouse monitoring, air conditioning and ventilation control, and routine weather monitoring.

GZ05 questions
What ranges are available for the GZ05?
Standard coverage is 0–5000 ppm, 1 ppm; 400–1000 ppm ±(50 ppm + 2.5% reading); 1001–2000 ppm ±(50 ppm + 3% reading); 2001–5000 ppm ±(40 ppm + 5% reading). 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 GZ05 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 GZ05 from qualified partners, inspect before shipment, and handle export documents and logistics.
Need the right digital carbon dioxide sensor for your process?
Send the medium, range, output, and quantity. We will confirm the matching option and a FOB Ningbo quote.
