Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›The Calorific Value Of Natural Gas Analyzer (model FDR‑4291) is designed to measure the heating value of gases used in steelmaking, cement kilns, biomass gasification and related industrial processes. It employs NDIR sensors to detect methane (CH4) and the collective concentration of hydrocarbon gases (CnHm) simultaneously, and it automatically calculates the calorific value based on those readings. The instrument includes a built‑in sampling pump, automatic zero calibration, a 320 × 240 LCD display and an RS232 digital output for data logging.
NDIR technology is the standard method for non‑dispersive infrared gas analysis because it provides high selectivity and stability for methane and hydrocarbon measurements. Typical industrial analyzers of this class offer a CH4 measurement range of 0‑100 % and a CnHm range of 0‑10 %, with a resolution of 0.01 % and an accuracy of about 1 % of full scale. The FDR‑4291 follows this industry norm and adds a convenient on‑board sampling pump to simplify field deployment.
The analyzer is suitable for blast furnace off‑gas monitoring, coke oven emissions, heat‑treatment furnace control, cement kiln flue‑gas analysis and biomass gasifier performance tracking. Suppliers often provide flexible order quantities and can ship the unit under FOB or CIF terms, allowing importers to select the most appropriate logistics arrangement for their project timeline.

Prior to purchase, confirm the analyzer’s measurement ranges, resolution, and accuracy match the specifications required for your process gas. Ask the supplier for a detailed data sheet, calibration certificates and, if relevant, proof of compliance with any industry standards such as ISO 9001 or IEC 61010.
Discuss logistics early: request the estimated lead time, preferred incoterms (FOB or CIF) and the payment terms the supplier is willing to accept. Verify whether the unit will be shipped from the nearest Chinese port and whether the supplier can provide a commercial invoice, packing list and any required export documentation.
Arrange for a third‑party inspection or factory acceptance test to verify sensor performance, calibration stability and the functionality of the built‑in sampling pump. Obtain the inspection report, test certificates and any warranty paperwork before finalising the shipment to ensure the analyzer meets your quality and safety expectations.
