Product Overview

Gas detectors offer high-precision detection technologies; higher gas concentrations can deplete electrochemical gas sensors, and either high or consistently low concentrations can shorten the sensor's lifespan.

The resource will deplete soon, and more maintenance is required. In the semiconductor industry, chlorine concentration poses a high risk, making it crucial to continuously monitor for leaks in dual gas pipelines.

One major advantage of ECtox is its ability to continue operating at high temperatures up to 200°C and under low concentrations, making it suitable for long-term use in environments with high concentrations of gases.

And it ensures a long service life, achieving industrial application in environments or extreme conditions without calibration throughout the lifespan of the solid-state polymer electrochemical gas sensor.

Maintenance-free technological innovation. Built-in miniature gas sampling device easily transports gases to the gas sensor. This product can detect gases in extreme environments.

This unit can directly sample and test gases at temperatures ranging from 200°C to -40°C, overcoming the technical challenge that electrochemical principles cannot operate in environments exceeding 55°C.

Long-term detection of dry gases is possible while ensuring longevity, overcoming the technical challenge that sensors based on electrochemical principles cannot be applied in dry environments.

The RS485 (Mod-bus) output signal can be easily connected to the gas detector host for display, or to the controller's DCS, PLC, or wireless system.

Principle of Detection

The ECtox gas detector utilizes solid-state polymer gas sensors, offering long life, durability, and selectivity. Based on specific electrochemical reactions,

Combined with a gas sampling device, this equipment can measure gas concentration over a wide range. The gas sensor measures the sampled gas after it reaches the working electrode of the sensor.

The sensor will undergo a chemical reaction with all the measured gases entering it, consuming all the gas provided. It will automatically generate gas reaction graphs.

Proportional to the ammonia concentration in the measured gas. Due to the use of solid-state polymer intelligent coulometric measurement technology, this product requires no calibration, has no maintenance needs, and features self-check of its lifespan.

The design of passive sampling is primarily based on gases of different densities, with diffusion and convection speeds typically slow or dependent on environmental conditions.

Based on the fact that the speed of molecular movement is affected by temperature and concentration differences, a passive sampling design can accelerate the flow of gases, timely capturing the measured gas.

Early detection of leakage conditions, or enhance response speed.
