The YSI ProDSS is a high-performance portable multiparameter water quality instrument engineered for comprehensive environmental sampling and field testing. Unlike single-parameter meters, the ProDSS handheld platform lets you connect up to four smart digital sensors simultaneously, measuring parameters such as dissolved oxygen, pH, conductivity, turbidity, algae indicators, salinity, and more. Designed for rugged use in surface water, groundwater, coastal, wastewater, and aquaculture environments, this customizable system provides reliable data with expandable cable options and smart sensor recognition.

Key Features:

• Modular Sensor Capability: Connect any combination of up to four ProDSS smart sensors using a 4-port cable assembly, giving you flexibility to adapt the meter to different monitoring needs. 
• Smart Sensor Recognition: ProDSS automatically recognizes connected digital sensors and retains calibration data within each sensor, reducing field setup time.
• Single Cable Sampling: Use a single rugged cable up to 100 meters long to bring sensors into the field while keeping the handheld unit safely on shore or a platform.
• Large Onboard Memory: Store over 100,000 data sets along with site lists and Data ID tags for organized projects and long-term sampling campaigns.
• Rechargeable Battery Power: Built-in lithium-ion battery delivers extended field operation, ideal for multi-day sampling without frequent recharging. 
• Color Display & Backlit Keypad: Easy-to-read interface and intuitive navigation help streamline field workflows in varied lighting conditions.
• Durable, Waterproof Design: IP-67 rated housing with rubber over-mold protects the instrument from harsh environments and wet conditions.
• GPS & Depth Options: Choose handheld models with optional GPS or depth sensors for enhanced spatial and vertical data context.
• Kor Software Included: Use Kor desktop and mobile tools for data analysis, calibration, configuration, and exporting results.
• Global Language Support: Multilingual interface supports users across regions and field teams.
• Comprehensive Warranty: Instrument warranty plus extended cable and sensor support.

Applications:
