Cole-Parmer WD-35432-02 pH/DO Meter, Oakton PD 650 Portable Waterproof

Overview

The WD-35432-02 is the meter-only version of Oakton's PD 650, a waterproof (IP67) portable instrument that measures pH, mV, ion concentration and dissolved oxygen together with temperature, displaying up to four parameters at once. Dissolved oxygen can be read as percent saturation from 0 to 600% or as concentration from 0.00 to 90.00 mg/L, with automatic barometric pressure compensation and salinity correction.

pH is resolved to 0.001 with ±0.002 accuracy, and up to six calibration points are recognized across USA, NIST, DIN and custom buffer groups. The meter stores 500 date-and-time-stamped data sets for GLP compliance, raises set-point and CAL-DUE alarms, and transmits data through IrDA or RS-232 over its LED link. Power comes from four AA batteries (about 200 hours) or the optional AC adapter.

Features

  • pH, mV, ISE, dissolved oxygen and temperature measurement
  • pH range -2.000 to 20.000, accuracy ±0.002 pH
  • DO 0-600% saturation and 0.00-90.00 mg/L
  • Automatic barometric and salinity compensation
  • 500 data sets with GLP date-and-time stamp
  • IrDA and RS-232 data output, calibration-due alarm
  • IP67 waterproof housing, password protection

Applications

  • Water and wastewater quality field testing
  • Environmental monitoring of lakes and effluents
  • Education and lab instruction in water chemistry

What's in the Box

  • WD-35432-02 PD 650 meter
  • 4 x 1.5 V AA batteries
