A handheld multiparameter instrument with multiple cable options
The YSI ProDSS (digital sampling system) handheld multiparameter meter provides extreme flexibility with two main cable options. Choose between the fully loaded 4-port cable assembly outfitted with any four DSS sensors (with depth or no depth) or the ODO/CT probe and cable – where you get accurate DO measurements every time with an optical dissolved oxygen sensor with an inline conductivity sensor, allowing for real-time salinity compensation.

FAQs:
- How often should I calibrate the meter?
Regular calibration is recommended before major surveys or when sensors are replaced. Use standard calibration solutions. - Can the YSI Pro Plus withstand harsh field conditions?
Yes. The IP-67 rating ensures waterproof protection. The rugged build is tested against drops, dust, and impacts. - What cable lengths are available?
Standard options include 1 m, 4 m, 10 m, and 30 m. Longer cables available on request. - What is included with purchase?
The base kit includes the instrument, standard cable, sensor(s), and quick-start guide. Accessories and consumables can be added.
