SX725 Portable pH/DO Meter Kit
The SX725 from Apera Instruments is designed for laboratory quality pH and dissolved oxygen (DO) measurement and is suitable for all general water solutions. The SX725's handy design as well as its dust and water resistance (IP57) and the rugged carrying case included in the scope of delivery make it ideal for field use, even in harsh environments. The integrated memory function allows 300 data sets to be stored and recalled. Possible applications include water treatment, environmental monitoring, beverage production, aquaculture, groundwater, surface water and aquarium monitoring, etc.
The 201T-S pH/temp. electrode included in the set enables fast and precise pH measurements due to its lithium glass membrane and ceramic diaphragm. Due to the integrated thermistor, temperature is additionally measured and an automatic temperature compensation is performed during pH measurement. For oxygen measurements, the polarographic DO500 electrode is supplied, which is polarized and ready for measurement after only 5 minutes. Due to its mode of operation, the automatic temperature and salinity compensation as well as the manual air pressure compensation, the electrode enables fast and precise DO measurements.
