Oakton WD-35632-02 Waterproof pH/DO 300 Handheld pH/Dissolved Oxygen Meter

The Oakton Waterproof pH/DO 300 Meter is a handheld micro-processor-based pH, dissolved oxygen (DO), and temperature meter with manual or automatic temperature compensation, salinity and pressure compensation, five-point pH calibration with automatic buffer recognition, and a backlit LCD screen with adjustable brightness to enable viewing in dark environments. The meter is used for aqua cultural, environmental, industrial, and educational applications and takes two probes: a pH electrode with BNC connector, and an Oakton DO/temperature probe with a notched 6-pin connector and a replaceable membrane cap. It has auto-ranging for DO measurements, and auto-buffer recognition for pH calibration. The meter has a hold function, a ready indicator, and automatic shutoff after 30 minutes of nonuse. The advanced setup mode allows customization of meter parameters and displays calibration values and electrode slope for both pH and DO for diagnostic reasons. The meter has European Conformity (CE) certification and is dustproof and waterproof, with Ingress Protection 67 (IP67). DO meters are commonly used in water-quality testing applications.
