HSCo standard solutions keep pH, conductivity, ORP and DO meters accurate. They are made for HSCo Master and Edge Series desktop, pen-type and portable meters: colour-coded pH buffers (4.00, 7.00, 10.01, and 1.68 and 12.46 pH), conductivity standards from 84 µS/cm to 111.9 mS/cm, 3 mol KCl electrode soaking solution, 222 mV ORP standard and DO electrolyte. They come in tightly sealed 250 mL or 500 mL bottles, batch-tested for consistency.
Why labs choose them
- Everything for calibration of pH, conductivity, ORP and DO meters.
- Colour-coded pH buffers for easy identification.
- Four conductivity standards, from ultra-pure water to brines.
- Tightly sealed bottles against contamination and evaporation.
- Batch-tested for consistent results.
