Description Vendor

The DA-600S-Catalytic is a smart gas detector/transmitter designed for detecting combustible gases, particularly hydrocarbons, using a catalytic sensing principle. The sensor operates by generating heat during gas oxidation, where combustible gases react with oxygen, causing a temperature change that is converted into an electrical signal via a Wheatstone bridge circuit. The device features a 2.4-inch TFT LCD display that shows real-time gas concentration and status information, along with RGB LED indicators for visual alerts. It supports auto-sampling using an internal micro-pump, enabling continuous gas detection even in difficult installation environments. Designed for hazardous environments, the detector has an explosion-proof structure and supports multiple communication outputs including 4–20 mA analog, RS485 Modbus, and relay outputs. It measures combustible gases in the range of 0–100% LEL and operates reliably under harsh environmental conditions.

Use Cases

  • Detection of combustible gases (e.g., hydrocarbons) in industrial environments
  • Gas leak monitoring in hazardous areas (Zone 1, Zone 2, Zone 21, Zone 22)

Capabilities

  • Measures combustible gas concentration in 0–100% LEL range
  • Provides 4–20 mA analog output, RS485 Modbus communication, and relay outputs
  • Supports user-configurable alarm levels and alarm types (HIGH/LOW combinations)
  • Enables automatic calibration without opening enclosure
  • Operates in harsh environments: -40°C to 55°C and up to 95% RH (non-condensing)
  • Continuous monitoring using suction-based sampling system
GASDNA Co.,Ltd GASDNA Co., Ltd, a South Korean company founded in 2004 and headquartered in Incheon, South Korea, has developed innovative and reliable gas measuring devices for over 20 years, becoming the first company in Korea to manufacture infrared thermometers and smart gas detectors, and now exports to more than 20 countries including Thailand, Malaysia, and Vietnam. The company develops and manufactures gas detectors and analyzers used across industrial sites, research facilities, semiconductor manufacturing, and hydrogen energy applications, providing advanced measurement solutions enabling real-time detection and analysis of hydrogen, oxygen, combustible gases, and toxic gases. GASDNA's smart gas detection solutions include both suction-type and diffusion-type smart gas detectors along with the MULTI-795 multi-gas analyzer and GMS-1700 controller, meeting international safety standards and holding certifications including ATEX, IECEx, CE, UL, and KOLAS, designed for use in factories, plants, laboratories, and hazardous environments requiring safety, accuracy, and fast response. On the hydrogen-focused B2B marketplace Hyfindr, GASDNA's product catalog spans a comprehensive range of hydrogen-specific detection and safety equipment including hydrogen detectors, flame detectors, conductivity sensors, and various hydrogen infrastructure equipment categories, positioning the company as a specialized safety technology provider for South Korea's expanding hydrogen energy sector alongside its established industrial infrared thermometer and smoke detector product lines.
