APERA Instruments SX731 tragbares pH-/ORP-/Leitfäh
The SX731 from Apera Instruments is designed for laboratory-grade pH, redox potential (ORP), conductivity (EC), total organic solvent (TDS), salinity, and resistivity measurements for all general water solutions. Its compact design, dust and water resistance (IP57), and the included rugged carrying case make the SX731 ideal for field use, even in harsh environments. The integrated memory function allows for the storage and recall of 300 data sets. Possible applications include water treatment, environmental monitoring, beverage production, aquaculture, groundwater monitoring, surface water monitoring, and aquarium monitoring, among others.
The 201T-S pH/Temp. electrode included in the set enables fast and precise pH measurements thanks 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 also measure temperature thanks to an integrated thermistor and perform automatic temperature compensation when measuring pH or conductivity. For precise and reliable ORP determination, the 301Pt-S ORP electrode is included, which is equipped with a high-quality platinum sensor. It does not require calibration and is easy to clean.
- Equipped with the 201T-S pH electrode, the 301Pt-S ORP electrode and the 2301T-S conductivity/temp. electrode
- Precise, fast and reliable measurement of pH, redox potential (ORP), conductivity (EC), TDS, salinity, resistivity and temperature
- Easy switching between conductivity, TDS, salinity and resistivity
- Fast & easy 1- to 3-point pH calibration and 1-point EC calibration
- A special digital filter technology further improves the response time and measurement accuracy
- The integrated memory function allows the storage and retrieval of 300 data records
- Dust and water resistant to IP57, ideal for use in harsh environments
- Supplied as a complete test kit in a robust carrying case
