The Gastec CO2 gas detector tube NO.2HH is a single‑use glass tube designed for on‑site measurement of carbon dioxide concentrations. It covers a measuring range of 2.5‑40 % CO2 by volume, suitable for many industrial ventilation and safety applications. Each tube is sealed at both ends and carries a calibrated colour‑change scale that can be read directly after exposure. The manufacturer states a shelf life of three years from the date of production.
Inside the tube a particulate matrix of silica gel and alumina holds a CO2‑sensitive reagent that produces a distinct colour band when the target gas is present. This construction follows the standard design of Gastec short‑term detector tubes, which are widely used for rapid, qualitative assessments in the field. Typical tube dimensions are about 150 mm in length and 12 mm in diameter, with an adjustable sampling volume of roughly 0.5 L.
The tubes are favoured by plant safety officers, HVAC technicians and environmental monitoring firms that need quick verification of CO2 levels without laboratory equipment. Henan Greeenland Tech Industrial Co. Ltd keeps a stock of this model and can dispatch orders within three working days, subject to confirmation of quantity. Buyers should confirm the exact lot number and quality‑control code printed on each tube to ensure traceability. Payment terms and incoterms are negotiated directly with the supplier, who notes a response window of 24 hours on working days.

Sourcing Gastec CO2 gas detector tube NO.2HH from Henan Greeenland Tech Industrial Co. Ltd - China Import Guide
Before placing an order for the Gastec CO2 tube, importers should request the current ISO, SGS or SEI certification copies that the supplier claims to hold, and confirm the production date printed on each tube to guarantee it falls within the three‑year shelf life. Verifying the unique quality‑control number on the glass helps trace the batch to the manufacturing lot and reduces the risk of receiving expired or counterfeit units.
Logistics arrangements are negotiated directly with Henan Greeenland Tech Industrial Co. Ltd. Buyers need to agree on the incoterm - typically FOB Zhengzhou or CIF Shanghai - and confirm the expected lead time, which the supplier notes as three working days for stocked items. Payment terms are usually a bank transfer against a pro‑forma invoice, but the exact schedule should be settled before shipment.
Upon arrival, purchasers should inspect the tubes for intact seals, clear calibration markings and the printed quality‑control identifier. A random sample can be sent to an accredited laboratory for colour‑change verification against a known CO2 concentration to ensure the reagents remain active. Retaining the supplier’s test certificates and the batch documentation will streamline customs clearance and downstream quality audits.
