Apera Instruments AI465 SX700 Series Handheld pH / DO Meter Kit

Apera SX725 is designed for lab-grade measurement of pH and DO (dissolved oxygen) in the field, suitable for general water solutions' applications such as water treatment, groundwater, surface water, hydroponics, environmental monitoring, aquaculture, aquarium, beverage making, etc.

Features:

• Intelligent functions -- auto. calibration, auto. temperature compensation, self-diagnosis, data logging, auto. power off, and more.
• Digital filter technology -- enhance the meter's response time and measurement accuracy
• Automatic electrode recognition -- the meter automatically switches to the right parameter mode according to the connected electrode
• Data logging -- 300 sets of data storage and recall
• Built tough -- IP57 water-resistant structure, ideal for use in harsh environment
• pH Electrode: The 201T-S pH/temp. electrode is featured with fast response and high accuracy. This electrode is suitable for general water solutions' pH testing. A 3M KCL storage bottle comes with the electrode to keep its sensitivity.
• Automatic pH Calibration: This meter can adopt 1 to 3 point automatic calibration, automatically recognizing 1.68, 4.00, 7.00, 9.18, 12.45. 3 bottled pH buffers are included (pH 4, 7, 10)
• Complete Kit: All the necessary buffers and accessories are included in the rugged carrying case
• DO500 DO Electrode: Apera's proprietary 3-in-1 polarographic DO electrode's polarization takes only 5 min vs. industry average 30 min. Measurement Range: 0-20.00mg/L Cable length: 2 meters Temperature unit: 30KΩ Thermistor
• Quick response: Measurement reaches 90% response within 30 seconds. When measuring DO in static water, keep swirling the electrode at a slow speed to get a stable reading. For details, please refer to the tutorial video.
• Easy DO Calibration: Easy calibration for saturated oxygen with the help of the calibration sleeve.
• Automatic Compensation for Higher Accuracy: Automatic compensation for temperature and salinity Manual compensation for barometric pressure (altitude)
