YSI ProODO Handheld Optical Dissolved Oxygen Field Kit with 4 Meter Cable
The YSI ProODO 4m Field Kit has a dissolved oxygen (DO) meter that uses an optical, luminescent-based technology and has direct salinity and altitude compensation, one-point DO calibration (or two-point with a 0% value), one-point barometer calibration, an internal barometer to ensure accuracy, onscreen instructions, and a backlit display and keypad for use in any lighting condition. The kit comes with a 4m field cable that has an optical DO probe. A digital signal sends information between the meter and probe. Calibration data are stored within the sensor, allowing the probe to be placed on another ProODO meter without re-calibration.
The meter has Automatic and Manual sampling modes, Continuous and Interval logging modes, and memory for 5000 data sets. It provides GLP (Good Laboratory Practice) data, has USB 2.0 connectivity (communications saddle and USB cable included), and comes with Data Manager PC software to manage data. The language is selectable in English, Spanish, German, French, Italian, Norwegian, or Portuguese. The rubber over-molded non-slip case adds durability and gripping ease. The meter runs on two alkaline C-cell batteries (included) and is impact-resistant and waterproof, with Ingress Protection 67 (IP67). Additional certifications include Restriction of Hazardous Substances Directive (RoHS), European Conformity (CE), Waste Electrical and Electronic Equipment Directive (WEEE), C-Tick, and Voluntary Control Council for Interference by Information Technology Equipment (VCCI). DO meters are commonly used in water-quality testing applications.
| DO range (mg/L) | 0 to 50mg/L |
| DO (mg/L) accuracy | 0 to 20 mg/L, + or - 0.1 mg/L or + or - 1% of reading, whichever is greater; 20 to 50 mg/L, + or - 10% of the reading |
| DO (mg/L) resolution | 0.01 or 0.1 mg/L (auto-scaling) |
| DO (%) range | 0 to 500% air saturation |
| DO (%) accuracy | 0 to 200% air saturation, + or - 1% of the reading or + or - 1% air saturation, whichever is greater; 200 to 500% air saturation, + or - 10% of the reading |
| DO (%) resolution | 0.1% air saturation |
| Barometer | Built-in barometer |
| Salinity input range | 0 to 70ppt; manual (automatically compensates for manual input value) |
| Weight (with batteries) | 475g (1.05 lbs) |
| Dimensions | 21.6 x 8.3 x 5.6cm / 8.5 x 3.25 x 2.21 inches (H x W x D) |
H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back
.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 environmental water quality monitoring and testing. The company, founded in 1948, is headquartered in Yellow Springs, OH.
