Brief Instruction
Thank you for choosing Apera Instruments SX736 Portable pH/DO/conductivity Meter (will be called “the
meter” in short in the following content). Before using the meter, please read this instruction manual
carefully in order to help you properly use and maintain it.
The meter can measure the parameters of pH, conductivity, TDS, salinity, resistivity, DO and temperature
of water solutions with high accuracy. It is suitable for various applications in different industries e.g.,
water treatment, aquaculture, horticulture, pools, beverage making, mining, power plants, environmental
monitoring, etc., especially ideal for in-field use.
The meter has the following features:
1.1.
Built-in microprocessor chip with the intelligent functions of auto. calibration, auto. temperature
compensation, auto. salinity compensation, manual baromatric pressure compensation, data storage,
function settings, auto. power off, and low voltage display etc.
1.2. Adopts digital filter technology to intelligently improve meter’s response speed and accuracy. The
smiley face icon will appear when the reading is stable.
1.3. Pure water modes available for pH and conductivity, significantly increasing the accuracy.
1.4 Unique 1-point conductivity calibration covering a wide range of 0 to 200mS, easy to use.
1.5. The polarographic DO electrode has a special electrode calibration sleeve. The electrode polarization
only takes 5 minutes. Electrode adopts a combo-style membrane cap, which is very convenient to use.
Each DO electrode comes with three backup membrane caps.
1.6. Meter’s LCD screen has clear and bright backlit display.
1.7. Built-tough. IP57 waterproof and dust-proof.
