Catalog nr.: 28APE190213
Menge
The SX731 from Apera Instruments is designed to measure pH, ORP, conductivity (EC), TDS, salinity and resistivity in laboratory quality and is suitable for all general water solutions. The SX731'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. The 2301T-S conductivity/temp. electrode is based on our unique BPB (Brush-resistant Platinum Black) electrode technology and is characterized by its precision and wide measuring range (0-200 mS/cm). Both electrodes can additionally measure temperature through an integrated thermistor and perform automatic temperature compensation when measuring pH or conductivity. For accurate and reliable ORP determination, the 301Pt-S ORP electrode is supplied, which is equipped with a high quality platinum sensor. It does not need to be calibrated and is easy to clean.
