YSI Pro1020

Handheld DO and pH or ORP Meter

The YSI Pro1020 provides field measurements for both DO and pH (or ORP) simultaneously. It features built in barometric compensation and all features standard to YSI's Professional series line.

The Pro1020 is the professional series instrument for use when only DO and pH (or ORP) measurements are required. It features many of the capabilities of the Professional Plus without the added cost of the ability for additional parameters. Both polarographic and galvanic DO probes are available and all readings are automatically compensated for both temperature and barometric pressure. In addition to dissolved Oxygen measurements, the Pro1020 simultaneously meaures either pH or ORP depending on probe selection.

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.

With it's large backlit display and 50 reading memory, the Pro1020 makes easy work of field measurements. As a Professional Series instrument it features excellent durability and is backed by a 3 year instrument and 2 year cable warranty.
