Carbon Dioxide (CO2) sensor / transmitter

EK Engineering offers a carbon dioxide (CO₂) sensor and transmitter designed for continuous online monitoring in industrial environments. The device measures concentrations from 0 to 20 000 ppm (0‑2 % vol/vol) using a non‑dispersive infrared (NDIR) sensor cell with a gold‑plated dual‑beam optical path. Output signals are provided as linear proportional analog 4‑20 mA or 0‑10 V, with an optional RS485 Modbus RTU interface for digital integration. The sensor operates on a 24 V DC supply and is rated IP65 with a hydrophobic and oleophobic filter, suitable for harsh conditions.

Typical accuracy for NDIR CO₂ sensors of this class is ±(50 ppm + 2 % of reading), and response time is generally under 30 seconds, which aligns with the performance of comparable instruments. The housing is made of polycarbonate and carries a UL‑V0 flame‑retardant rating, a common requirement for equipment installed in confined or explosive‑prone areas. Operating temperature range of 0 °C to +50 °C matches standard environmental limits for indoor and mildly heated installations. The device complies with CE marking standards, a typical certification for electronic instrumentation sold in many markets.

Typical applications include cold‑storage monitoring for fruits such as apples and mangoes, controlled‑atmosphere chambers for kiwis, furnace and conveyor belt environments, and emission monitoring in incinerators. Process engineers, quality managers and automation specialists are the primary buyers of this sensor. EK Engineering can ship the units from Udaipur, India, and offers standard packaging in anti‑static boxes with accessories for mounting. Trade terms are not specified in the listing, so buyers should confirm FOB or CIF options, lead‑time estimates and acceptable payment methods such as T/T or L/C before ordering.

EK Engineering is based in Udaipur, India, and is listed as an imported tier supplier with a voyage trust tier, indicating basic verification on the platform. The profile shows a response rate of 0 % and no average response time, so communication may require proactive follow‑up. The company specialises in industrial instrumentation and offers CO₂ sensors among other measurement devices. No further details on production capacity, certifications or years of operation are provided, so buyers should request such information directly.

Potential purchasers should ask for CE test reports, calibration certificates and details of the UL‑V0 housing certification. EK Engineering states that the sensors can be shipped from its Udaipur facility, with standard packaging suitable for international freight. Importers must verify that the device complies with local regulatory requirements for electronic equipment and gas detection. Clarifying lead‑time, incoterms and payment terms with the supplier will ensure smooth procurement.
