YSI Pro20 Dissolved Oxygen and Temperature Handheld Meter
YSI Pro20 Dissolved Oxygen and Temperature Handheld Meter
The YSI Pro20 dissolved oxygen meter is a rugged, user-friendly instrument for measuring dissolved oxygen or BOD that can be used interchangeably in the lab and the field. Depending on your needs, you can choose between a Polarographic DO sensor, a Galvanic DO sensor, or a BOD probe.
Available YSI-compatible sensors are EPA-approved for reporting BOD, CBOD, and DO in wastewater compliance.
Instrument Only. Cables, probes/sensors, and accessories are sold separately.
Features:
- User-replaceable sensors and cables
- One Touch Cal for convenient and quick calibration
- Choice of DO sensor (Polarographic or Galvanic) or lab BOD probe for BOD in wastewater
- Military spec connectors, IP-67 waterproof, and 1-meter drop tested
- Rubber over-molded case
- Low total cost of ownership
- Internal barometer for highest accuracy
- 95% response in 8 seconds with standard membrane
- Stores 50 data sets
- Graphic, backlit display and glow-in-the-dark keypad visible with polarized sunglasses on
- Available with 1, 4, 10, 20, 30 or 100-meter cables
- Multiple languages including English, Spanish, French, and German
