Product Overview

HI97701-11 Free and Total Chlorine CAL CheckTM standards provide a simple solution for calibrating and verifying the HI97701 free chlorine photometer with a range of 0.00 to 5.00 mg/L (ppm). This set of high-quality standards is manufactured in our state-of-the-art facility and comes with a Certificate of Analysis. The Certificate of Analysis provides the lot number, reference value, and expiration date for traceability when certifying the HI97701 photometer.

• Certificate of Analysis provided

• Standard value for free and total chlorine at 25°C is 1.00±0.03 mg/L (ppm)

• Reusable with long shelf life and good stability

HI97710-11 is a set of high-quality calibration standards that allows users to verify and calibrate the pH range in compatible portable photometers with a pH range of 6.5 to 8.5. HI96710-11 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 pH 7.0±0.1@25°C. The calibration kit is produced in our state-of-the-art manufacturing facility using reagent-grade chemicals in a temperature-controlled environment.
