HI-7014 Pool Line Free Chlorine Checker Handheld Colorimeter suitable for use in swimming pools, hot tubs and spas.
The presence of free chlorine, in combination with a correct pH value, ensures that bathing water is clear and disinfected. The concentration of free chlorine in swimming water should be measured regularly. The HI-7014 bridges the gap between simple chemical testing kits and professional instruments. This checker uses an EPA approved DPD method.
- Specifically for free chlorine
- More accurate than chemical testing kits
- Large LCD
- Small size, great convenience
- One-button operation
- Operates on 1 single AAA battery
Four easy steps to testing
Step one – Add a sample to the included cuvette
Step two – Insert sample into the Checker HC and press the button to zero
Step three – Remove sample and add reagent as stated in the manual
Step four – Reinsert sample and press the button to measure your results

| PLEASE NOTE: |
|
In some cases, samples may contain other parameters which may interfere with results |
| Interference may be caused by: |
|
Bromine, Iodine, Ozone, Oxidized forms of Chromium and Manganese. In case of water with hardness greater than 500 mg/L CaCO3, shake the sample for approximately 2 minutes after adding the powder reagent.
- If the water used for this procedure has an alkalinity value greater than 250 mg/L CaCO3 or acidity value greater than 150 mg/L CaCO3, the colour of the sample may develop only partially, or may rapidly fade. To resolve this, neutralise the sample with diluted HCl or NaOH.
