The YSI Pro20i Dissolved Oxygen Meter, 10 m Cable, Polarographic (59353-44) is a portable dissolved oxygen and temperature meter supplied with an integral 10 m cable and polarographic DO probe. It measures dissolved oxygen from 0 to 500% air saturation or 0 to 50 mg/L, with automatic barometric pressure compensation and rapid push-button calibration.
Key Features
- 10 m integral cable with polarographic DO probe, providing a complete portable configuration for dissolved oxygen and temperature measurement
- Three-second dissolved oxygen calibration, using one-touch operation for fast instrument setup
- Automatic barometric pressure compensation, supporting accurate dissolved oxygen calibration and measurement
- Wide dissolved oxygen measurement range, covering 0 to 500% air saturation and 0 to 50 mg/L
- User-selectable dissolved oxygen resolution, offering 0.1% or 1% air saturation and 0.01 or 0.1 mg/L
- Temperature measurement from -5 to 55°C, with 0.1°C resolution and ±0.3°C accuracy
- Manual salinity compensation from 0 to 70 ppt, allowing entered salinity values to be incorporated into measurements
- Memory for 50 data sets, reducing the need to record individual readings manually in the field
- IP67 waterproof construction, with a rubber over-moulded case designed for demanding field use
- Backlit graphic display and illuminated keypad, supporting operation in low light and visibility while wearing polarised sunglasses
- Prestretched screw-on membrane caps, simplifying membrane installation and routine sensor maintenance
- Approximately 400 hours of battery operation, powered by two included C-cell batteries without the backlight in use
Benefits
- Speeds up field measurements with rapid calibration and straightforward one-touch operation.
- Supports sampling at greater reach with the integrated 10 m cable and polarographic dissolved oxygen sensor.
- Reduces manual record keeping by storing up to 50 measurement sets within the instrument.
- Provides reliable field usability through waterproof construction, a slip-resistant rubber over-mould and an easy-to-read display.
- Simplifies routine sensor maintenance with user-replaceable polarographic sensing components and prestretched membrane caps.
- Supports extended field sessions through long battery life and a battery-life indicator.
