Product Details

YSI ProDSS portable multi parameter water quality measuring instrument

YSI ProDSSPortable multi parameter water quality measuring instrumentUsed for point measurement and profile measurement of pH, redox potential, and dissolved oxygen. This product can be applied to surface water, groundwater, coastal waters, and aquaculture areas. The durable and reliable ProDSS can measure up to 17 parameters, and users can replace sensors with information. Color display, large capacity memory storage, convenient calibration steps, rechargeable battery, and powerful PC data management program (KorDSS) make user experience more user-friendly. The product has the advantages of full customization and durability.

Instrument features:

1. Multi parameter selection: dissolved oxygen (optical), turbidity PH、 Redox potential, conductivity to specific conductivity, salinity, total dissolved solids, depth, ammonia nitrogen, ammonia gas, chloride, nitrate, temperature, seawater density, seawater depth
2. The cable universal interface can connect 4 sensors and depth sensors
3. Rechargeable lithium batteries have a long lifespan and provide power for handheld hosts and sensors
4. Large capacity memory storage (>100000 sets of data) with a large number of sampling location lists and data identity tag functions
5. The instrument comes with a data management software called KorDSS, which has data geographic annotation function
6. Global Positioning System (GPS) (optional)
7. It is divided into two types: with depth sensor and without depth sensor, and a single cable can reach up to 100 meters in length
8. External rubber casting, sturdy and IP-67 waterproof shell, as well as metal and military grade joints
9. Handheld devices and KorDSS use multiple languages, including English and Chinese (simplified and traditional)
