Gastec H2S gas detection NO.4H
The Gastec H2S gas detection NO.4H is a short‑term detector tube designed to measure hydrogen sulphide concentrations. It is calibrated for a measuring range of 10‑4000 ppm and carries a shelf life of three years from the date of production. The tube is identified as model 4H and features a thin glass body with a printed calibration scale for direct reading. Each unit is hermetically sealed at both ends and bears a unique quality‑control number.
Inside the tube a particulate matrix of silica gel and alumina binds highly stable detection reagents that change colour when exposed to H2S. Production lots are tested and calibrated independently to ensure precision, a practice typical for Gastec short‑term tubes. The design follows industry standards for on‑site gas monitoring, offering a tolerance that suits environmental and petrochemical applications. Typical dimensions for such tubes are about 100 mm in length and 12 mm in diameter, allowing easy handling in the field.
Field technicians in oil‑field, wastewater treatment and safety inspection use these tubes for rapid on‑site assessments. Henan Greeenland Tech Industrial Co. Ltd states a 20‑year export record and can dispatch stocked items within three working days, though exact MOQ and Incoterms should be confirmed with the supplier. Buyers are advised to request the supplier’s ISO, SGS or SEI certificates and to verify the tube’s batch QC number before placing an order.

Sourcing Gastec H2S gas detection NO.4H from Henan Greeenland Tech Industrial Co. Ltd - China Import Guide
Before placing an order, confirm that the supplier can provide current ISO, SGS or SEI certificates and ask for a copy of the batch quality‑control number printed on the tubes. Verify the three‑year shelf life claim and ensure the tubes will be stored under recommended temperature and humidity conditions during transit and warehousing.
Discuss logistics early: ask the supplier which Incoterms they can accommodate, typical lead times for stocked versus made‑to‑order items, and whether they offer consolidation at the port of Shanghai or other Chinese gateways. Clarify any minimum order quantity and freight options, as these details affect total landed cost and delivery scheduling.
Arrange for a third‑party inspection if large volumes are required, requesting test reports that confirm colour change response and calibration accuracy. Ensure the supplier supplies a Certificate of Conformity and a detailed packing list so customs clearance proceeds smoothly. Maintaining clear documentation will help protect quality and compliance throughout the import process.
