SP-710B Handheld Water Multimeter

6 Key Parameters. 1 Robust Handheld.

Measures for 6 key water treatment parameters including: pH (0–14), ORP (±1,500mV), Conductivity (0–15,000µS/cm), PTSA (0–300ppb), Fluorescein (0–600ppb), & Temperature (32–104 ºF).

CE Mark




The SP-710B handheld multimeter is capable of measuring up to 6 key water treatment parameters simultaneously. With the SP-710B you can measure for pH, Conductivity, PTSA, Temperature, ORP and Fluorescein, making it perfect for boiler water applications. The unit offers a Bluetooth® enabled & fully potted, battery powered pH/ORP module, eliminating water and KCI contamination to the meter.. The new module design offers wireless communication to the base unit and can also be viewed via the uPyxis® app.

The SP-710B has other features in addition to its measuring capabilities. Among these a fully molded screen to ensure a water-proof seal. Then it also has an integrated humidity sensor to ensure a water-free electronic environment.  Thirdly the platform stores history for all measurements which can then be transferred via Bluetooth® to smartphones or computers using uPyxis®.

Unmatched in the water treatment market. The one-handed operation combines electrochemical and optical measurements in a cuvette-less platform. This unique technology simultaneously measures and compensates for Color and Turbidity contamination of the water sample during fluorescence testing, ensuring precise measurement capability ±1ppb resolution.

Typical Applications

The SP-710B can do all the the functions previously described. However it was mainly designed for cooling tower  and boiler tank applications.  It is very heat and melt resistant making it perfect for the previously described examples.
