What is chloride measured for?
Chloride (Cl-) is a naturally occurring anion in water and an important indicator of water quality. The limit value for drinking water is 250 mg/l Cl- (Drinking Water Ordinance). Elevated chloride concentrations promote the corrosion of metal pipes and can indicate contamination.
The HR test set (High Range) covers a large measuring range of 0.2 – 300 mg/l and is particularly suitable for monitoring drinking water, groundwater and industrial process water.
How does the test set work?
The CALDUR® Chloride HR test set is based on the mercurimetric method. After adding two reagents to the water sample, a coloration develops, the intensity of which is precisely determined with the WINLAB Data Line photometer.
Advantages of the CALDUR® test set
- Large measuring range 0.2 – 300 mg/l Cl-
Covers the entire drinking water range and beyond
- 120 determinations per set
Economical for continuous use
- High precision due to photometric evaluation
Objective, reproducible measurement results with the WINLAB Data Line
- Quick analysis in just 2 minutes
Ideal for frequent routine checks
Areas of application
Carrying out the measurement:
- Fill water sample into round cuvette up to the mark
- Add reagent A and mix
- Add reagent B and mix
- Wait for 2 minutes reaction time
- Insert the cuvette into the WINLAB Data Line photometer and start the measurement
Important notes
- Adhere exactly to the reaction time of 2 minutes
- For values above 300 mg/l: dilute the sample and convert the measured value
- Wipe the cuvette with a lint-free cloth before measuring
- Requires WINLAB Data Line Photometer (sold separately)
