When a wider range of chemical tests may be required, or the flexibility to add tests at a later date is desirable, a comparator block using the wheel comparator method is a great choice.
- Fast and simple testing of multiple chemical parameters
- Easy to switch between tests simply by inserting a different wheel
- Chemical reagents can be purchased separately saving money and storage space, giving maximum flexibility
- A wide range of chemical tests available
- Provided in a case to avoid damage during transport and use
