Import Biogas Analyzer — Buy in Bulk from Supplier in China

Wuhan Cubic Opto Electronics Co., Ltd manufactures a rack-mounted biogas analyser measuring methane 0 to 100%, carbon dioxide 0 to 50%, oxygen 0 to 25% and hydrogen sulphide 0 to 9,999 ppm. The unit achieves precision of plus or minus 2% for CO2 and CH4, plus or minus 3% for O2, and plus or minus 4% for H2S, with resolution of 0.01% for the first three gases and 1 ppm for H2S. Response time is below 20 seconds after the 10-minute warm-up period, enabling rapid process monitoring in anaerobic digestion and landfill gas applications. Output interfaces through RS232 serial communication, with AC220V plus or minus 10% at 50Hz plus or minus 1Hz power requirement. The 19-inch rack, 3U casing format and 10 kg weight suit control room or mobile laboratory installation rather than field-deployable portable use.

The analyser employs non-dispersive infrared detection for CH4 and CO2, the standard method for these symmetric molecules, with electrochemical or similar technology for O2 and H2S. The measurement ranges accommodate typical biogas compositions, where methane dominates at 50% to 70%, carbon dioxide at 30% to 50%, with trace oxygen and corrosive hydrogen sulphide at hundreds to thousands of ppm. The specified precision levels indicate process-grade rather than laboratory research-grade instrumentation, suitable for combustion control, gas engine protection and basic emission monitoring. The 20-second response time suggests continuous flow analysis rather than discrete batch sampling, with gas conditioning requirements unspecified. Rack mounting in 3U format implies 133.35 mm panel height, compatible with standard 19-inch equipment cabinets common in industrial control systems.

Primary users include anaerobic digestion plant operators, wastewater treatment facilities, landfill gas recovery projects and agricultural biogas installations requiring continuous compositional monitoring. The RS232 output allows integration with SCADA systems, data loggers or building management platforms, though modern Ethernet or 4-20 mA interfaces may require additional converters. Buyers should confirm whether the supplier provides gas sampling pumps, filters, dryers or conditioning systems, as biogas saturated with moisture and particulates damages unprotected analysers rapidly. Calibration gas requirements, recommended intervals, and availability of spare sensor modules are critical lifecycle cost factors. Import from Wuhan, Hubei Province, involves standard Chinese export procedures for analytical instruments, with buyers responsible for confirming voltage compatibility, local certification requirements such as CE marking or ATEX approval for explosive atmospheres, and after-sales technical support accessibility.

Wuhan Cubic Opto Electronics Co., Ltd is located at Floor 10, Building 6, SBI Street, Hongshan District, Wuhan, Hubei Province, 430074, China. The supplier holds an imported tier designation with harbor trust tier, indicating cross-border trading activity with baseline platform verification. The response rate is 0.00% with zero average response hours, which may reflect a newly established export division, data synchronisation issues, or limited English-language sales capacity rather than non-operation. Buyers should initiate contact through multiple channels, email and telephone, to assess current responsiveness and technical support capability before relying on this supplier for time-critical projects.

The company name suggests specialisation in optoelectronic instrumentation, with biogas analysis representing one application of gas sensing technology. The product range visible from this listing focuses on fixed-installation process analysers rather than portable field instruments. No information is provided about year of establishment, research and development staff, production floor area, annual output, revenue, or specific quality certifications such as ISO 9001, ISO 14001, or product-specific approvals. The supplier does not state whether they manufacture the sensor modules in-house or integrate third-party components. Buyers should request company registration documents, quality management system certificates, and reference installations in comparable biogas applications, ideally with contactable end users for performance verification.
