Features:

Part Number: 17134461 (1713-4461)

Detected Gas: O₂ (Oxygen)

Detection Principle: Electrochemical principle, built-in integrated PCB signal board, dedicated adapter for Ventis MX4 four-in-one detector, not compatible with ordinary oxygen sensors

Adapter for Host: Ventis MX4 Portable Four-in-One Gas Detector (Universal for Diffusion / Pump Sampling Models)

II. Core Electrical & Performance Parameters

Measurement Range: 0 - 30% VOL (covers hypoxia, normal air, and oxygen-rich conditions)

Resolution: 0.1% VOL, can accurately identify minor oxygen concentration changes

Accuracy Error: Linearity, repeatability, hysteresis ≤ ±5% FS

Operating Temperature Range: -20℃ - +50℃, suitable for indoor and outdoor, high and low temperature industrial sites

Output Method: Analog voltage signal, direct insertion into the host pin, no need for external conversion circuit

Service Life: Original factory guaranteed for 18 months, actual use in normal conditions lasts 1.5 - 2 years

Response Characteristics: Fast response, real-time warning in limited spaces and emergency rescue situations

Structure: Cylindrical plug-in type, integrated sealed dustproof and moisture-proof, industrial explosion-proof design

Power Supply: Powered by the 3.6V internal power supply of the MX4 detector host, no need for an independent power source

III. Core Functions and Applications

1. Core Function

Real-time monitoring of environmental oxygen concentration, preventing two types of safety risks: hypoxia suffocation (＜19.5% VOL) and oxygen-rich explosion (＞23.5% VOL). It is the standard core probe for four-in-one detectors.

2. Industry Application Scenarios

Limited space operations

Sewage wells, basements, storage tanks, pipelines, ship cabins, cellars; continuous oxygen measurement before and during operations, automatic audible and visual alarm in case of hypoxia.

Petrochemical / Coal Chemical Industry

Storage tank maintenance, reaction vessels, enclosed workshops, prevent oxygen deficiency caused by inert gas replacement, and prevent oxygen-rich gas explosion.

Mining, Metallurgy

Mine tunnels, smelting enclosed furnaces, underground pipeline inspections.

Fire emergency rescue

Fire scenes, enclosed fire scenes, basement search and rescue, quickly determine the oxygen content at the scene to ensure the safety of firefighters.

Municipal Engineering

Gas pipelines, underground pipelines, sewage treatment plants, septic tank cleaning.

Ships, cold storage, laboratories

Cold storage nitrogen preservation replacement, laboratory inert atmosphere operation, ship cabin inspection.

3. Equipment Matching Applications

As an original replacement part for Ventis MX4 detector, the oxygen sensor of the equipment ages, fails, or drifts, it can be directly unplugged and replaced. After replacement, simple calibration can restore the entire machine's detection function. It can be combined with CO, H₂S, LEL combustible gas components to form a complete four-in-one safety monitoring system.
