SX725 Portable pH/DO Meter Kit

Product Description:

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.

Brief Intro

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)
