Total Hardness CAL Check™ Standards – HI96735-11

The HI96735-11 Total Hardness CAL Check™ standards provide a simple solution to calibrating and validating the HI96735 Total Hardness EPA Portable Photometer that features three measurement ranges. The HI96735-11 CAL Check^TM 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 HI96735 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

Details

HI96735-11 is a high quality set of calibration standards that allows users to validate and calibrate the HI96735 Total Hardness EPA Portable Photometer that has a full range of 0 to 750 mg/L (ppm) CaCO₃. The HI96735-11 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.
