pH CALIBRATION Check™ Standards HI97710-11
- Supplied with Certificate of Analysis
- Standard value of pH 7.0 ±0.05 @ 25°C
- Reusable with long shelf life stability
HI97710-11 is a high quality set of calibration standards that allows users to validate and calibrate the pH range found in compatible portable photometers that have a 6.5 to 8.5 pH range. The HI96710-11 includes one sealed “A” cuvette for zeroing the meter and one “B” cuvette that is used to validate or calibrate. The expected reading from the “B” standard is pH 7.0 ±0.1 @ 25°C. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
