Trotec OZ-ONE – ozone meter

Ozone meter

With the ozone meter OZ-ONE you have the ideal testing instrument for a quick and precise check or the long-term detection of ozone concentrations in the ambient air. The OZ-ONE is characterised by a very low cross-sensitivity to other gases or VOCs and impresses with quick, highly accurate measurement results even at very low ozone concentrations.

Many integrated functions such as the ozone zero adjustment, the reference value measuring option for short-term exposure limit (STEL) and time-weighted average (TWA), or the value display, switchable from ppm to µg/m³ and vice versa, make the quickly responding OZ-ONE an indispensable tool for precise ozone exposure measurements. Moreover, this device is a compact portable environmental measuring device for the determination of air temperature and humidity or the calculation of dew point and wet-bulb temperature. The dual display of this measuring device always shows you two measured values at a time, visible at a glance.

Key features

  • Quick and precise determination even of low ozone concentrations
  • Indication of the measured ozone value in ppm or µg/m³
  • Fast response time
  • Minor cross-sensitivity to VOCs
  • Ozone zero adjustment function
  • Ozone reference value measurement (STEL/TWA)
  • Atmospheric pressure offset for high-precision standard cubic metre measurements
  • Measuring air temperature and humidity
  • Calculating dew point and wet-bulb temperature
  • Offset adjustment for air temperature and humidity
  • Data hold, MAX/MIN and alarm function
  • Display illumination
  • ¼ inch threading for tripod connection
  • In addition to battery operation, mains operation for non-stop measurements also permitted
  • Energy-saving automatic switch-off
  • Incl. calibration certificate

For long-term measurements the OZ-ONE can also be attached  to a tripod. In addition, the measuring device houses both a mini USB port and a barrel-type 9 V coaxial power socket. These ports permit a continuous mains operation as alternative to the battery-powered application. Last but not least, to ensure a mobile power supply via the mini USB port the OZ-ONE may also be connected to a powerbank.
