Ethylene sensor (ethylene gas concentration meter) MH2 (Japan Only)

High sensitivity measurement even in low temperature environments
Automatic zero point correction function supports continuous measurement
Easy-to-use design for both installation and transportation

An easy-to-use ethylene sensor!

The usual method for measuring ethylene is gas chromatography, but this is very expensive.
Furthermore, when measuring by gas chromatography, the analysis must be performed in an environment such as a laboratory.
Our products have been development as sensors that can perform continuous measurements in the field.
The product is easy to operation and works well with our sensors and various devices, so we can also suggest combinations.
If you are considering a demo or purchasing, please feel free to contact us!

high accuracy and high resolution!

It is known that when measuring ethylene gas with an electrochemical sensor, sensitivity is not achieved in low temperature environments.
features of our ethylene gas sensor is that it can measure low concentrations of 0 to 100 ppm even in low temperature environments.
Furthermore, it has an excellent resolution of 0.01 ppm, allowing for precise measurements.
