Oakton Waterproof PD 650 pH/Dissolved Oxygen Meter

The Oakton WD-35432-00 PD 650 pH/dissolved oxygen (DO) multi-parameter meter measures your choice of pH, mV, or ISE and dissolved oxygen (DO), and is handheld, dustproof and has a waterproof casing. The meter features ATC, with push-button, pH calibration up to six points each, for pH and conductivity, and three points for DO. It also has auto-buffer options, and recognition of USA, National Institute of Standards and Technology (NIST), Deutsches Institut für Normung (DIN) and PWB standards, for ease of use. It has a large, backlit, LCD screen to provide ease of viewing, and to display indicators. The meter has an adjustable alarm to remind you when calibration is due. It stores up to 500 data sets, and has IrDA wireless technology for data communication. The meter has a built-in, real time clock with time and date stamping, set-point alarms, and a built-in stand. It comes with an electrode status indicator and password protection.

The meter has manual or automatic temperature compensation of 0 to 100 degrees C. It has a pH range of -2.00 to 20.00, resolution of 0.1/0.01/0.001 and accuracy of + or - 0.002 pH + 1 LSD. Temperature compensation range of -10.0 to 110.0 degrees C (14.0 to 230.0 degrees F), resolution of 0.1 degree C (0.1 degree F), and an accuracy of + or - 0.5 degrees C (+ or - 0.9 degrees F). MV range is + or - 2000.0, resolution of 0.10, and accuracy of + or - 0.2 mV + 1 LSD. Ion range is 0.001 to 19900, ppm, molar, mg/L, resolution of 2 or 3 digits, and accuracy of 0.5% FS (monovalent) 1% FS (divalent). DO range is 0 to 600%/90 mg/L, resolution of 0.1%, 0.01 mg/L, accuracy of + or - 2%, + or - 0.2 mg/L. The dissolved oxygen probe is galvanic. The meter dimensions are 2.25(d) x 3.25(w) x 7.25(h) inches (8.3 x 18.4 x 5.7 cm), and it weighs 380g (without rubber boot). The meter has the ability to store up to 500 data sets, and has research-grade accuracy. Time and date stamping meets Good Laboratory Practice (GLP) standards, and the meter is Ingress Protection (IP) 67-rated, for protection against solid objects or liquids. The meter works with four 1.5V AA batteries (not included) or optional AC adapter.

pH testers measure the acidity or alkalinity of a liquid or substance and are commonly used by researchers, manufacturers, and hobbyists. Dissolved oxygen meters are used in a variety of applications to monitor the amount of oxygen present in water. Applications include sewage and water treatment plants, pollution control, fish farms, and various types of manufacturing.
