The Pro20 handheld DO meter can switch between lab and field work in a matter of seconds due to its interchangeable cables and probes. Featuring some of the fastest response times in a handheld DO meter (< 8 seconds), automatic barometric compensation, salinity compensation via user supplied values, and easy one touch calibration, the Pro20 allows you to complete your field work quickly and accurately.
The large, graphic, LCD display is easy to read (visible even while wearing sunglasses), and both the display and keypad are backlit. The Pro20 can store 50 sets of data for later review, eliminating the need to write results down. Field cables are available in lengths ranging from 1 to 100 meters, and can use either galvanic or polarographic DO probes. A 2 meter cable with a self stirring BOD probe is also available for lab use.
When deciding between galvanic or polarographic field DO probes, the deciding factor is sensor warmup time vs longetivity. Galvanic sensors require no warmup period and can begin taking readings immediately. Polarographic sensors need 5 to 15 minutes of warmup before measurements can be taken, but have a longer sensor life. Both types of DO probes provide accurate measurements and fast response times.
Like the rest of the Professional Series line from YSI, the Pro20 is IP67 rated (even with the battery cover off), floats, and has military spec connectors. The interface is easy to use and can operate in multiple languages. Power is provided by 2 C alkaline batteries which allow for up to 400 hours of runtime. The Pro20 is backed by a 3 year instrument warranty and a 2 year cable warranty.
YSI Pro20 DO meters consist of the instrument, cable, and probe, all purchased seperately. This allows you to choose a configuration suitable for your application, and to order multiple cables/probes to create a versatile instrument that can be reconfigured by simply changing cables.
To order the Pro20 choose the instrument, a cable, and a DO probe (the BOD lab cable includes the probe). Accessories like carrying cases, flow cells, and replacement DO membrane kits are also available
