Portable pH/Dissolved Oxygen Meter DO Meter for Water and wastewater treatment/Pond water and aquarium
Multiparameter portable pH/Dissolved Oxygen meter contains the 2 measurement modes, the meter is suitable for measuring the pH and DO.Expanded memory stores and recalls up to 500 data sets.
pH Mode:
• Multiparameter portable pH/dissolved oxygen meter is equipped with a backlit LCD display.
• 1 to 5 points push-button calibration with auto-buffer recognition.
• Selectable pH buffer group (USA/NIST/DIN) or using the custom calibration solutions.
• Automatic electrode diagnosis with pH slope and offset display.
Dissolved Oxygen Mode:
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
• Salinity and barometric pressure compensations ensure the reliable DO measurements.
Includes electrode:
1,pH electrode
2, Dissolved oxygen probe:
3, Temperature probe
