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 Polaris TGP Total Gas Meter
The OxyGuard Handy Polaris TGP (Total Gas Pressure) Meter is a hand-held gas pressure meter that doubles as a dissolved oxygen meter. It can operate in three display modes- as a standard Handy Polaris dissolved oxygen (DO) meter, as a TGP meter displaying percent saturation, or as a TGP meter displaying pressures as volume percentage values. The user can choose which value is shown on the display. DescriptionThe instrument also incorporates a data logger. Menu functions, along with an intuitive interface, make the Handy Polaris TGP/DO/Temperature meter easy to use for novice and experienced users alike. The OxyGuard Handy Polaris TGP/DO/Temperature Meter also includes a membrane kit (10 O-rings/10 membranes), 50 ml electrolyte, membrane installation tool, and cathode cleaning pad. Technical AdvantagesMeter The Polaris 2 TGP is designed for easy use and to give accurate here-and-now measurements of both the dissolved oxygen and the dissolved rest gases - i.e. the gases that can cause decompression sickness - “the bends” - in fish. This is achieved because the instrument measures all three pressures needed - the dissolved oxygen, the total dissolved gas and the atmospheric. Maintenance is easy - the DO measurement is made using the well-known OxyGuard Handy probe, and the TGP measurement tube sensor element can easily be exchanged if necessary. Probe The OxyGuard TGP probe can be directly connected to OxyGuard Commander, Convoy and Pacific systems. It can only be used with these systems. It does not need a separate transmitter or input unit, but communicates values directly. Only one field bus data cable connection is needed - the cable has cores for both data and the 24 V DC supply needed by the probe. The TGP is designed for easy use. The measurement tube is wound on a central bobbin that is held in place by the protector. If the tube becomes fouled you simply unscrew the protector, unplug the bobbin and tube and fit a replacement. Precise measurements are obtained by placing the TGP in the air and matching - or calibrating - the TGP against the barometric pressure sensor of the DO Meter or Pacific of the system. This means that a very accurate value of the difference between the gas pressure in the water and the gas pressure in the air can be obtained. The pressure measurements can also both be calibrated against the absolute value of the barometric pressure if this is known accurately. The TGP has the same diameter as a standard OxyGuard probe so that standard mounting devices can be used. Specifications Dimensions: Meter 98 mm diameter x 36 mm Probe: 58 mm x 110 mm + cable gland Cable Length: Standard 3 m. Other on request. Operating Conditions: Probe: -5 to +45°C, meter -20 to +60°C. Encapsulation (meter): Short-term immersion proof to 5m depth. Display: Graphical LCD display. Variable backlight. Parameters measured: Oxygen partial pressure, atmospheric pressure, total dissolved gas pressure, temperature at probe. Parameters displayed: DO in mg/l, % sat, % vol. TGP in % sat. Rest gas in % sat, % vol. Temperature in °C or °F. Measuring range, DO: 0-60.0 ppm (mg/l), 0-600% saturation and 0-60% vol. Oxygen Probe Type: Galvanic cell, self polarizing, self temperature compensating. DO measurement automatically compensated for temperature and barometric pressure. Manual salinity compensation between 0-59 ppt salinity. DO accuracy depends on calibration accuracy. Typically better than +/- 1% of measured value +/- 1 digit within the standard measuring range. DO measurement repeatability typically better than +/- 0.5% of measured value. Response Time (DO) 90% of end value in less than 20 seconds in water. Measuring range, pressures: to over 200% sat, 2 bar. Accuracy +/- 2% of value Measuring range, temp: -5 to +45°C. Accuracy +/- 0.2°C. Self-check of: Probe function, meter function, cable, battery. Accessories included: Storage pouch, DO probe membranes with O-rings and electrolyte, cathode cleaning pad, storage pouch.
