Smart Digital-Process Gas Detector - MULTI-795 (Auto-Suction Type)

GASDNA Co.,Ltd

Simultaneous detection of O₂, H₂, CO, CH₄, and CO₂
Auto-suction system with built-in micro pump and BLDC motor
Multi-technology sensing: Optical, TCD, and NDIR
7” TFT LCD display with real-time monitoring and graphical visualization
Built-in data logging with USB backup and CSV export

The MULTI-795 is an auto-suction type digital process gas analyzer designed for continuous multi-gas monitoring in industrial environments. It is capable of simultaneously measuring O₂, H₂, CO, CH₄, and CO₂ using a combination of optical, TCD, and NDIR sensing technologies. The system integrates a micro pump with BLDC motor for automatic gas suction, enabling continuous and stable sampling. It supports multi-channel measurement with independent outputs for each gas and delivers reliable performance even in environments containing combustible gases due to its optical sensing approach. The device features a 7-inch TFT display, real-time data visualization, and built-in data logging with USB backup functionality. It provides industrial communication and control through 4–20 mA outputs, RS-485 communication, and relay alarm outputs.

Use Cases

Continuous monitoring of multi-gas environments in industrial processes
Hydrogen and mixed-gas analysis in energy and process systems
Monitoring combustible and non-combustible gases in controlled environments

Capabilities

Continuous gas sampling via automatic suction system (micro pump)
Multi-channel output (up to 5 channels) with 4–20 mA analog signals per gas
Digital communication via RS-485 (Modbus RTU)
Configurable alarm system with relay outputs and delay settings
User-configurable calibration, alarm thresholds, and detector parameters
