hmos ozone sensor

Oxygen Accessories | Amsons Technologies

There are three primary technologies used to monitor and measure ozone: Electrochemical cells, HMOS / GSS, and UV. Electrochemical ozone sensor uses a porous membrane that allows ozone gas to diffuse into a cell containing electrolyte and electrodes. When ozone comes into contact with the electrolyte, a change in electrochemical potential occurs between the electrodes causing electrons to …

Ozone levels are shown on the easy-to-read multicolor graphical display. LED readout changes color as ozone levels increase: green indicates a safe level, yellow is caution level, and red is the danger level. Both models feature a heated metal oxide semiconductor (HMOS) sensor for excellent sensitivity and quick response time. Compact monitors measure only 2-3/8"W x 3-¼"H x 1-3/8"D.

What Are Ozone Monitors, and How Do They Work ...

2021-03-17· In an HMO, a metal piece is heated. This metal piece contains an electrical current. When ozone interacts with this metal, the current changes. The monitor then provides a reading, letting you know ozone is present. These sensors take a longer time to boot up. After the first use, you will have to wait 10 minutes. Once the sensor is ready for use, it will take at least one minute to deliver ...
