Pro20 Dissolved Oxygen Meter, DO: 0 to 500%, 0 to 50 mg/L, Temperature: -5 to 55°C, Barometer: 400 to 999.9 mmHg, YSI (CAT#: STEM-AIAE-0040-ZJF)

The Pro20 Dissolved Oxygen Meter manufactured by YSI is a rugged, user-friendly instrument for the measurement of dissolved oxygen, temperature, and barometric pressure.
The Pro20 is designed to be rugged, simple, and reliable. EPA-approved sensors are available for monitoring BOD, CBOD, and DO in wastewater.
The Pro20 can be used in the lab or the field and can be switched between them in a matter of seconds.
With its user-replaceable sensors and cables, as well as its convenient One Touch Cal feature, this device is extremely user-friendly. A mil-spec (military specification) connector, an IP-67 waterproof and rubber over-molded case, and a 1-meter drop test ensure that the instrument will remain in your hands for many years of sampling regardless of harsh field conditions. Over the life of the product, the Pro20 has a low total cost of ownership.
With Polarographic and Galvanic dissolved oxygen sensors, you can complete your sampling routine quickly. Polarographic sensors have a long life, which saves you time and money. With the Galvanic sensor, you can begin sampling immediately without the need for a warm-up period. No matter which sensor you choose for the field, you will receive accurate, quality data.
