Overview

In the industrial fields of dyes, plastics, fragrances, and organic synthesis, 1,1-diethoxyethane (commonly known as acetaldehyde, chemical formula C ₆ H ₁₄ O ₂) is a commonly used solvent or intermediate. Its vapor is flammable and volatile, and if leaked beyond the standard, it may not only cause explosions but also endanger the health of workers. The ERU-PG51SPOM fixed formaldehyde gas online monitoring and alarm detector is designed specifically for this type of working condition, which can achieve 24-hour continuous monitoring and accurate warning of formaldehyde vapor concentration. It is an important equipment to ensure the safety of the production environment.

固定式乙缩醛气体在线监测报警探测器

1,1-diethoxyethane (also known as acetaldehyde) is commonly used in chemical, solvent, coating, ink, adhesive, and organic synthesis intermediate production processes as a solvent or intermediate for volatilization. After its vapor evaporates into the air, it belongs to the "highly flammable liquid and vapor" type. If the ventilation conditions in the production workshop, storage tank area, pipeline or enclosed space are poor, once a leak occurs, the concentration of formaldehyde in the air may reach the lower explosive limit or pose a health hazard to the human body. Therefore, it is necessary to equip fixed online formaldehyde gas detection and alarm devices in these application sites to achieve 24-hour continuous real-time monitoring and alarm, early warning, and timely processing.

The ERON-PG51SPOM fixed online 1,1-diethoxyethane (ethylene glycol) gas detection alarm developed and produced by Yingrun Group adopts a fixed online installation. It collects ethylene glycol vapor in the air in real time through diffusion (optional pipeline/circulation/pump suction), converts its concentration into an electrical signal using high-precision sensors, and after internal circuit processing, displays the real-time concentration value intuitively on a 1.7-inch high-definition color screen. When the concentration reaches or exceeds the preset alarm threshold, the instrument immediately triggers a local sound and light alarm. At the same time, the data is remotely transmitted to the duty monitoring host through RS485, 4-20mA and other signals, achieving remote synchronous display and centralized management, and can be linked to control exhaust fans and other equipment to reduce on-site risks.

Fixed online 1,1-diethoxyethane (formaldehyde) gas detection alarm product features:

★real-time monitoringContinuous detection of formaldehyde concentration in the air, with a resolution of 0.1 ppm (electrochemical) or 0.01% LEL (catalytic combustion).
