Buy & Import CH-D3 Miniature Size Combustible Gas Pellistor from Week Technology Ltd. - Wholesale Supply

The CH-D3 miniature size combustible gas pellistor is a compact sensor designed for detection of methane in portable gas detectors. It measures 11.5 mm high and 15 mm diameter and weighs under 10 g. It provides a sensitivity of 10‑17 mV per % methane, a measurement range of 0‑100 % LEL, a response time t90 of less than 12 seconds to reach 50 % LEL, and a linearity of 6 % methane at 5 % non‑linear. Certified to ATEX, IECEx, UL and CSA, it operates from - 40 °C to +50 °C and consumes 190 mW at 3.0 V ±0.2 V.

The pellistor is housed in a flame‑proof chamber, typically constructed from stainless steel for corrosion resistance. Its miniature dimensions complement the existing Alphasense D‑sensor family, enabling battery‑life optimisation in handheld devices. Standard industry practice classifies such sensors under IEC 60079‑10 for hazardous‑area equipment, and they are designed for low power draw and high poison resistance.

Typical users include safety‑equipment integrators and OEMs producing portable gas analyzers for mining, oil‑gas and environmental monitoring. The supplier lists the unit weight and voltage but does not disclose MOQ, price or lead time; importers should request bulk pricing and shipping terms such as FOB or CIF directly from Week Technology Ltd.

Frequently Asked Questions About CH-D3 Miniature Size Combustible Gas Pellistor from Week Technology Ltd.
The sensor outputs 10‑17 mV per percent of methane concentration, covering the full 0‑100 % LEL detection range. This level of sensitivity supports low‑level methane monitoring in portable detectors.

Sourcing CH-D3 Miniature Size Combustible Gas Pellistor from Week Technology Ltd. - China Import Guide

Before placing an order, confirm that the CH‑D3 units carry the ATEX, IECEx, UL and CSA certificates claimed, and request the test report for the 190 mW power draw. Ask the supplier for the calibration certificate covering the 10‑17 mV/% methane sensitivity and for material certification of the stainless‑steel housing. Verify that the dimensions (11.5 mm height, 15 mm diameter) match the space available in your detector design.

Discuss logistics by requesting the preferred Incoterm, such as FOB Shenzhen port or CIF, and obtain an estimated lead time for bulk shipments. Clarify payment terms, for example a T/T deposit followed by balance against the bill of lading. Because the supplier’s public response rate is currently 0 %, establish a reliable communication channel before confirming the order.

Arrange a pre‑shipment inspection focusing on visual housing integrity, voltage compliance and functional testing at 0 % and 100 % LEL methane. Request a test report for response time and linearity as specified. Ensure the supplier provides a full inspection certificate and a copy of the hazardous‑area certification prior to shipment.
