Product Overview

• HI97735-11 Total Hardness CAL CheckTM standards provide a simple solution for calibrating and verifying the HI97735 Total Hardness Photometer with a range of 0 to 750 mg/L (ppm). These high-quality standards are manufactured in our state-of-the-art facility and come with a Certificate of Analysis. The Certificate of Analysis provides the lot number, reference value, 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 a long shelf life

• HI97735-11 is a set of high-quality calibration standards that allow users to verify and calibrate the HI97735 Total Hardness EPA Portable Photometer with a full range of 0 to 750 mg/L (ppm) CaCO3. HI97735-11 includes a sealed “A” cuvette for zeroing the meter and a “B” cuvette for verification or calibration. The expected reading for the “B” standard is 150±10 (low range), 350±15 (medium range), and 520±20 (high range) mg/L CaCO3@25°C. The calibration kit is produced in our state-of-the-art manufacturing facility using reagent-grade chemicals in a temperature-controlled environment.
