Pro1020 YSI Professional Series Instrument

Rugged and reliable, this handheld instrument measures dissolved oxygen, temperature, and your choice of either pH or ORP. Simply select the probes and cable length to meet your needs. All cables provide temperature measurements with no separate temperature probe needed. Dissolved oxygen is measured using either a polarographic or galvanic sensor. Smart calibration allows the instrument to remember previous calibration values, allowing for fast dissolved oxygen calibration in two button pushes. The Pro1020 stores 50 data sets, boasts a quick response time, features a backlit display, and is protected by an impact-resistant IP67 waterproof housing.
