Product Overview

HI96735-11 Total Hardness CAL Check™ Standards provide a simple solution for calibrating and verifying the HI96735 Total Hardness EPA Portable Photometer, which features three measurement ranges. HI96735-11 CAL CheckTM Standards can be used for total hardness determination in the low (0 to 250 mg/L CaCO3), medium (200 to 500 mg/L CaCO3), and high (400 to 750 mg/L CaCO3) ranges. This set of high-quality standards is manufactured in our state-of-the-art facility and comes with a Certificate of Analysis. When certifying the HI96735 photometer, the Certificate of Analysis provides the lot number, reference values, and expiration date for traceability.

• Certificate of Analysis provided

• Standard values are 150±5 (low range), 350±7 (medium range), 520±10 (high range) mg/L CaCO3@25°C

• Reusable, long shelf life, and good stability

HI96735-11 is a set of high-quality calibration standards that allows users to verify and calibrate the HI96735 Total Hardness EPA Portable Photometer, with a full CaCO3 range of 0 to 750 mg/L (ppm). HI96735-11 includes a sealed “A” cuvette for zeroing the meter and a “B” cuvette for verification or calibration. The expected readings for the “B” standard are 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.
