Hanna HI749-11 Chromium Low Range Checker HC

Hanna HI749-11 – Calibration Standard Set for Chromium VI Low Range Checker HC

The Hanna HI749-11 is a high-precision calibration standard set designed for validating the performance of the Hanna HI749 Chromium VI Low Range Checker HC. This set includes two sealed cuvettes: one representing a zero ppb chromium VI sample, and another tinted to simulate a 100 ± 5 ppb chromium VI concentration at 25°C.

Key Features 

• Reliable Instrument Validation
  This set allows you to regularly confirm the accuracy of your HI749 Checker HC. As a result, you can reduce false positives or inaccurate low-range readings in your chromium VI analyses.

• Includes Two Sealed Cuvettes
  The package contains:

  • One cuvette filled with a 0 ppb Chromium VI solution

  • One cuvette tinted to match 100 ± 5 ppb Chromium VI

• Laboratory-Grade Accuracy
  Manufactured using reagent-grade chemicals under controlled conditions, each calibration set ensures high reliability and traceability.

• Easy to Use
  Simply insert the cuvettes into your HI749 Checker HC and verify whether the readings fall within the acceptable calibration range—no mixing or preparation required.

• Essential for Routine QC
  Regular use of this calibration standard helps maintain measurement confidence, particularly in professional water quality control and environmental monitoring applications.
