Chlorine Pooltester,visual,bloc,2 scales

General Description:
Pooltester Chlorine/pH, visual colour comparison, block type, with two residual chlorine scales.

Technical Specifications:
Simple Chlorine/pH test kit (Pool Tester) for visual testing of residual chlorine in drinking water (colour comparator).
Using two colorimetric scales for chlorine residual, enabling both low and high levels of chlorine to be monitored, and one colorimetric scale for pH, on the same transparent plastic material block (clear polyacrylate material or similar).
Measuring ranges
- for Chlorine LR from 0 to 1.0 mg/l
- for Chlorine HR from 0 to 6.0 mg/l
- for pH from 6.8 to 8.4

Supplied in appropriate pocket-size hard plastic case with reagents for minimum 50 tests of each (i.e. at least with 50 DPD No. 1 and 50 Phenol Red rapid dissolving tablets).

Accessories/Spare parts/Consumables:
If required, the following items should be ordered separately:
S0000555 - DPD 1 Rapid, for Free Chlorine.
S0000559 - DPD 3 Rapid, for Total/Combined Chlorine.
S0000561 - Phenol Red Rapid, for pH.

Weight/Volume/Dimensions:
Estimated weight: 120 g
Estimated volume: 130 ccm

Instructions for use:
The simple pool/block tester is used for testing for Free (Residual) Chlorine in drinking water using DPD 1 tablets, and Phenol Red tablets for determining the pH level. Simply dip the test block in the water, add the tablet(s) and read the result from the colour scale.

Combined Chlorine can potentially be determined by adding DPD 3 for Total Chlorine to the sample containing DPD 1 and from the Total result calculate the difference with Free Chlorine. It has to be noted that in case DPD 3 tablets are employed, the user should ensure a proper cleaning of the test cell and lid after each test to avoid false reading of Free Chlorine afterwards (due to DPD 3 generally containing potassium iodide).

Though photometer grade tablets can be used, they need to be crushed. It is recommended to use DPD No. 1 Rapid Dissolving tablets (see Consumables references above) with these non-electronic Visual Pool/Block Comparators, for more appropriate/safe (ease of) handling.
