The YSI 550A-12CC instrument is a dissolved oxygen (DO) and temperature meter for measuring DO in fresh, sea, or polluted water in the field, with a 50’ cable-probe assembly and a backlit LCD to enable reading in dark or dimly lit areas. This microprocessor-based, digital meter has automatic temperature compensation for DO, automatic salinity compensation (0 to 70ppt) for DO, and altitude compensation for calibration. The weighted, quick-sinking polarographic probe has a field-replaceable electrode module and screw-on cap membrane. It runs on 4 alkaline C-cell batteries (included), has a waterproof case with Ingress Protection 67 (IP67), and has European Conformity (CE) certification. DO meters are commonly used in water-quality testing applications.

Dissolved oxygen (DO) meters measure the amount of dissolved oxygen present in water. The amount of DO helps to determine, for example, drinking water quality, the health of lakes or streams, and aquatic organism sustainability. A probe, also called a sensor or electrode, is inserted into the sample to perform the measurement, and the results appear on the meter display. Applications include sewage and water treatment plants, pollution control, fish farms, and various types of manufacturing. YSI manufactures instruments, sensors, and software for e...

User-replaceable sensors and cables and convenient Quick Cal feature makes it extremely user friendly. Mil-spec (military spec) connectors, IP-67 waterproof and rubber over molded case, and 1-meter drop tests ensure the instrument remains in your hands to provide years of sampling even in the harshest field conditions. The feature set of the Pro2030 results in a low total cost of ownership over the life of the product and proves that it is smarter, tougher, and more versatile. Fast response times with the Polarographic or Galvanic DO sensor allows you to complete your sampling routine quickly. The long life of the Polarographic sensor saves time and money and reduces your overall cost. The Galvanic sensor enables you to start sampling immediately without a warm-up period. Either sensor you choose for the field will give you accurate, quality data. The super-stable 4-electrode conductivity cell is built into the cable and will provide years of accurate data. The cells are designed for rugged field performance and are easily cleaned and require minimal maintenance. Choose field DO sensors (Polarographic or Galvanic). Quick Cal allows DO calibrations within seconds with the push of a button. Stores 50 data sets. Graphic, backlit display and glow in the dark keypad. Fastest DO response time on the market with 95 percent response in 8 seconds with standard membrane. Multiple languages include English, Spanish, French and German. Conductivity cell built-in. Conductivity: +/-0.5 percent of the reading or 1.0 uS/cm, whichever is greater. Power: 2 alkaline C-cells providing approximately 400 hours of battery life depending on backlight usage; low battery indicator. Salinity Input Range: 0-70 ppt; automatic - uses conductivity reading; DO compensated for salinity values. Waterproof: IP-67 (even with the battery cover off). Conductivity Reference Temp: Adjustable; range 15 degree C to 25 degree C.

If your Dissolved Oxygen Sensor has not been used for over a year, the HDPE sensing membrane could have dried out, leaking internal electrolyte solution from the probe. This maintenance kit no only revives dried-out sensors, it keeps them maintained for a longer shelf-life. The Atlas Scientific Dissolved Oxygen Maintainence Kit comes with a replaceable HDPE sensing membrane and probe with refillable electrolyte chamber. Although it is not necessary to replace the sensing membrane or electrolyte solution during normal operation, the membrane can be damaged if it is hit with fast moving debris in the water. This kit has everything to get your Dissolved Oxygen Sensor up-and-running. Founded in 2005, Atlas Scientific is the industry leader in embedded chemical sensing. This highly specialized company focuses all of its resources on manufacturing the best chemical sensors and test chemicals on the market today. Atlas Scientific proudly offers its technology to individuals, industry professionals, and defense contractors worldwide.
