Portable pH, Conductivity & Ion Meters

Apera's portable meters add more professional functions, durability and reliability for work in the field and in harsh conditions. The SX700 Handheld Series runs from the SX711 pH/mV meter to the SX751, which measures up to eight parameters — pH, ORP, dissolved oxygen, conductivity, TDS, salinity, resistivity and temperature — and recognises the connected electrode automatically. The 400 Series covers pH, conductivity and ions, and the 400S Series adds GLP data management and USB output — 1,000 groups of storage on the PC400S. The ION400-NH and ION400-K measure ammonium and potassium ions, with 15 common ions pre-configured and custom ions definable.

The 850 Value and 8500 Premium series cover pH, conductivity and pH/conductivity, plus application-specific pH kits for beverages, dairy and liquid food, flat surfaces, hydrofluoric acid, high temperatures, small samples, meat, pure water, strong alkalis, soil and semi-solid food. The PC8500 connects pH and conductivity electrodes at once, logs 500 sets of GLP data with USB output and web-based PC-Link software, and is sealed to IP57 with a foldable stand for bench use; its 0–200 mS/cm conductivity range extends to 1,999 mS/cm with the K=10 electrode.
