Total Hardness CAL Check™ Standards - HI97735-11
The HI97735-11 Total Hardness CAL Check™ standards provide a simple solution to calibrating and validating the HI97735 Total Hardness EPA Portable Photometer that features three measurement ranges. The HI97735-11 CAL CheckTM standards can be used for the low (0 to 250 mg/L CaCO3), medium (200 to 500 mg/L CaCO3), and high (400 to 750 mg/L CaCO3) ranges of total hardness determination. This high quality set of standards is manufactured in our state-of-the-art facility and comes supplied with a certificate of analysis. The certificate of analysis provides the lot number, reference values, and expiration date for traceability when certifying the HI97735 photometer.
- Supplied with Certificate of Analysis
- Standard value of 150 ±5 (low range), 350 ±7 (medium range), 520 ±10 (high range) mg/L CaCO3 @ 25°C
- Reusable with long shelf life stability
HI97735-11 is a high quality set of calibration standards that allows users to validate and calibrate the HI97735 Total Hardness EPA Portable Photometer that has a full range of 0 to 750 mg/L (ppm) CaCO3. The HI97735-11 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 150 ±10 (low range), 350 ±15 (medium range), and 520 ±20 (high range) mg/L CaCO3 @ 25°C. The calibration set is produced in our state-of-the-art manufacturing facility using reagent grade chemicals in a temperature controlled environment.
