CHECKIT Comparator Chlorine DPD, tablet reagents
Use it to measure chlorine in water by the DPD method, matching the colour developed by tablet reagents against a colour disc. Each version is set up for one test range, from 0.02 to 0.3 mg/L up to 0 to 4 mg/L Cl2. The 0.02 to 0.3 mg/L version uses the D 55 comparator with mirror optics, and the other versions use the standard-optics comparator.
Highlights
The method table lists Chlorine D55 T, LR T, MR T and HR T. Together they cover 0.02 to 4 mg/L Cl2 across the four versions.
DPD No.1 and DPD No.3 Evo tablets are listed with a minimum shelf life of 5 or 10 years.
Each version includes 30 DPD No.1 tablets, 30 DPD No.3 Evo tablets, two 10 ml plastic cuvettes with lid and a 10 cm stirring rod.
The 147000 version, 0.02 to 0.3 mg/L, ships with the CHECKIT Comparator D 55 with mirror optics. The other three use standard optics.
Methods and ranges
The table lists all 4 methods. Each version runs the one test for its range, with DPD No.1 and DPD No.3 Evo tablets.
| Parameter | Range | Method | Reagent |
|---|---|---|---|
| Chlorine D55 T | 0.02 - 0.3 mg/L Cl₂ | DPD | DPD No.1 and DPD No.3 Evo tablet reagents |
| Chlorine LR T | 0 - 1 mg/L Cl₂ | DPD | DPD No.1 and DPD No.3 Evo tablet reagents |
| Chlorine MR T | 0 - 2 mg/L Cl₂ | DPD | DPD No.1 and DPD No.3 Evo tablet reagents |
| Chlorine HR T | 0 - 4 mg/L Cl₂ | DPD | DPD No.1 and DPD No.3 Evo tablet reagents |

Common questions
What measuring range does the Lovibond CHECKIT Comparator Chlorine DPD cover?
The range depends on the version. Code 147000 covers 0.02 to 0.3 mg/L Cl2 (Chlorine D55 T). Code 147010 covers 0 to 1 mg/L (LR T). Code 147040 covers 0 to 2 mg/L (MR T). Code 147020 covers 0 to 4 mg/L (HR T).
Which method and reagents does it use?
It uses the DPD method with tablet reagents. Each version is supplied with 30 DPD No.1 tablets and 30 DPD No.3 Evo tablets. Reading is by comparison against the CHECKIT Disc Chlorine DPD.
Does it measure free chlorine, total chlorine or both?
The specification does not state this. It lists only the method as DPD and the reagents as DPD No.1 and DPD No.3 Evo. If you need to confirm what the result represents for your application, ask us before ordering.
What is the difference between 147000 and the other versions?
The 147000 version is supplied with the CHECKIT Comparator D 55 with mirror optics. The other versions are supplied with the standard-optics comparator. The diffuser panel on the backside is described only for the standard-optics comparator.
What is included in the box?
You receive the comparator with the colour disc, 30 DPD No.1 tablets and 30 DPD No.3 Evo tablets. You also receive 2 plastic cuvettes of 10 ml with lid and a 10 cm plastic stirring rod. An instruction manual, warranty information and a carrying case are included.
How long do the reagent tablets last?
The datasheet gives a minimum shelf life of 5 or 10 years. It does not say which figure applies to which tablet. Ask us if you need the figure for a specific batch.
