Overview
Enviro Testers Portable Ozone Gas Detectors for O3 Air Treatment are small, handheld devices that measure the concentration of ozone gas in the air. They have a digital display that shows the current ozone level in parts per million (PPM), as well as an alarm that sounds when the ozone level reaches a preset threshold. The detectors also have a memory function that stores the highest and lowest ozone levels that have been recorded.
Features
- Imported Japanese high precision electrochemical sensors.
- USB High – speed datum transfers; Data print downloadable (OPTIONAL)
- Gas concentration unit: PPM or Mg/m3 display
