    YSI YSI ProSolo ODO/CT Kit

    The ProSolo ODO/CT kit includes the digital ProSolo handheld; an optical dissolved oxygen, conductivity, and temperature cable/probe assembly (4 or 10 meter cable length); and a soft-sided carrying case. The ProSolo handheld is the direct replacement for the ProODO Optical Dissolved Oxygen handheld. OverviewODO® Sensor Technology Dissolved oxygen measurement technology has advanced from electrochemical sensors, such as polarographic and galvanic, to luminescent-based, optical sensors. YSI optical DO sensors are non-consumptive, meaning oxygen is not consumed during the measurement. As a result, there is no flow dependence or stirring required with ODO, allowing for the most accurate readings in the field. Advantages over electrochemical sensors include: Higher accuracy with no stir dependence Less drift over time; holds calibration longer Less maintenance; no membranes or electrolyte Real-Time Salinity Compensation With an integral conductivity module, the ODO/CT probe assembly enables the ProSolo to automatically compensate DO mg/L measurements for changes in salinity. The 4-electrode conductivity cell, designed for rugged field performance, is easily cleaned and requires minimal maintenance. Technical InfoProDIGITAL Smart Sensors In addition to utilizing the most advanced DO sensing technology, the ProSolo incorporates smart sensor technology that enables sensors to be automatically recognized by the handheld. Additionally, DIGITAL sensors store calibration data, so probe assemblies can be swapped between handhelds without the need for re-calibration. Provides Years of Sampling for All Field Conditions The ProSolo handheld meets the demands of true field work with a rugged, waterproof case (IP-67 rated) and a military-spec (MS) cable connector. Rigorously drop tested from all angles, the handheld features a 3-year warranty, while a 2-year warranty is included with the probe assembly and ODO Cap. Advanced Data Management ProSolo includes KorDSS Software, a powerful data management program for easy 2-way communication between the meter and a PC. A unique data backup feature allows for the export of data to a USB flash drive (included) in csv format without having to connect to a computer. Convenient Sampling Experience Ergonomic handheld for a comfortable grip Easy-to-read color display and backlit keypad Large onboard memory with storage capacity for over 100,000 data sets Site ID and Data ID tag capabilities for data organization Data export directly to USB flash drive (included) Single cable design for probe assembly lengths ranging from 1- to 100-meters Long-life rechargeable lithium-ion battery that is user-replaceable Simple and quick calibration procedures Size 2.46 cm diameter, cable options for 1, 4, 10, 20, 30, 50, and 100 m lengths Dissolved Oxygen ​(Optical luminescence)Units: % saturation, % saturationlocal, mg/L, ppm Range: 0 to 500%, 0 to 50 mg/L Accuracy: 0 to 200%: ±1% of reading or 1% saturation, whichever is greater 200 to 500%: ±8% of reading 0 to 20 mg/L: ±0.1 mg/L or 1% of reading, whichever is greater 20 to 50 mg/L: ±8% of reading Resolution: 0.01 mg/L and 0.1%, or 0.1 mg/L and 1% (auto-adjusts based on range) Temperature (Thermistor)Units: °C, °F, K Range: -5 to 70°C (temperature compensation range for DO mg/L measurement: -5 to 50°C ) Accuracy: ±0.2°C Resolution: 0.1°C or 0.1°F (auto-adjusts based on range) Conductivity (Four nickel electrode cell)Units: μS/cm, mS/cm Range: 0 to 200 mS/cm Accuracy: 0 to 100 mS/cm ±0.5% of reading or .001 mS/cm, whichever is greater 100 to 200 mS/cm ±1.0% of reading Resolution: 0.001, 0.01, or 0.1 mS (range dependent) Specific Conductance Units: μS/cm, mS/cm Range: 0 to 200 mS/cm Accuracy: 0 to 100 mS/cm ±0.5% of reading or .001 mS/cm, whichever is greater 100 to 200 mS/cm ±1.0% of reading User selectable reference temperature (15 to 25°C; default 25°C) and compensationcoefficient (0 to 4%/°C; default 1.91%) Resolution: 0.001, 0.01, 0.1 mS/cm Warranty 2 years on cable, probe, and ODO sensor cap

    OxyGuard OxyGuard Handy Salinity Meter

    The Handy Salinity is a hand-held instrument specially designed for aquaculture use. Factory calibration and automatic temperature compensation make it very easy to use. The display shows the salinity directly. Temperature is also measured and shown in the display. The instrument incorporates automatic check functions to ensure reliability. The probe is designed to be as trouble-free as possible, with features specially suited for aquacultural use. Inductive technology is used so that you don’t have to worry about deposits on the surface of the probe – all you have to do is ensure that the hole in the probe is open and relatively clean.
