OZ-21P Ozone meter literatureThe OZ-21P Ozone Meter, handheld, 0-2mg/l provides an instant measurement of dissolved ozone in potable water by the use of a polarographic sensor.
This unit is similar in technical operation to the Residual Chlorine Meter, Low range, 0-2ppm.
A unique beads polishing system incorporated at the electrode system maintains the electrode in good working condition, free of interferences at the gold microelectrode, and ensures stable measurement.
The meter also indicates the sample temperature and includes a built-in-clock. The instrument can store one set of results (measurement, temperature and time) in memory for later retrieval. Power is provided by two standard AA batteries which have an operating life of up to 50 hours.
Features
- Reagent Free, low operating cost
- Simple measurement by pressing start button after immersion
- Auto hold function is available
- 0-2mg/l measuring range
- Stable measurement by polarograph method using beads polishing system
- Data storage memory for 300 sample results
- External printer option
