pH/Dissolved Oxygen (DO) Meter

• Measures pH, dissolved oxygen and temperature.
• Waterproof, dustproof and it floats.
• Automatic temperature compensation from 0 to 50°C.
• Displays pH/temperature or oxygen/temperature.
• Salinity correction: range 0 to 50 ppt resolution 0.1 ppt
• Barometric pressure correction: range 500 to 1499 mm Hg/66.6 to 199.9 kPa, resolution 1 mm Hg/0.1kPa
• Key salinity and barometric pressure manually. Both give automatic correction.
• Independent 100% and zero adjustment calibrations.
• View slope, offset and millivolt values for both pH and DO.
• °C/°F selectable.
• Auto pH buffer recognition and calibration at 5 points.
• Hold function, ready indicator and auto shutoff.
• Easy-to-service, low maintenance probe.
• Power: 4 x 1.5V AAA batteries included (>100 hours of continuous use).
• Dimensions: 3.75”W x 7.5”L x 2.25”H
• Meter kit includes meter, DO probe with 10-ft cable, pH electrode with 10-ft cable, pH “Singles” pouches, 500 ml electrolyte solution, 5 replacement membranes, membrane replacement tool, rinse bottle and foam-lined hard carrying case.
• Warranty: 3 years.
