No hazardous chemicals or organics
- Use as relative mV standard and calibrate offset of sample
- Redox potential values are 215 mV for Ag/AgCl reference electrodes and 420 mV for standard hydrogen reference electrodes
These stable, ready-to-use standards require no mixing and contain no organics or hazardous chemicals — use straight out of the bottle. Choose from two convenient package sizes for use in the lab or field.
