Colorimeter kit - Lovibond Nessleriser 2150 AF325 for Pt-Co/Hazen/APHA

The Lovibond® AF325 is a special kit for visual colour grading using Platinum-Cobalt/Hazen/APHA Colour over the range 10 - 250 mg Pt/L. It is typically used for lighter coloured liquids such as water, oils and chemicals. Because the sample colours are relatively unsaturated, the kit employs a long path length Nessleriser comparator to give greater measurement sensitivity and accuracy. The Comparator 2000+ is an easy-to-use, entry level colour measurement system that compares the colour of the sample directly against the colour of glass in a disc. All you need to do is rotate the disc to get the closest result to the scale.

Greater measurement sensitivity and accuracy for lightly coloured liquids: The Lovibond® AF325 is a visual test kit is ideal for relatively unsaturated liquids due to its extended path length.

Fast, economical & portable visual matching: The Comparator 2000+ is a flexible, modular system for Visual Colour Grading. Using a suitable comparator instrument and glass disc, you can quickly visually match the sample directly against the calibrated, colour stable glass standards.

Two-field vision for accurate results: Lovibond® comparator instruments include an integrated prism which causes the sample and comparison fields to overlap, allowing enhanced colour discrimination and matching. The prism is ultrasonically sealed to prevent contamination of the optics. Each individually graded glass standard represents a discrete step on the measurement range (as opposed to a continuous graduation), aiding colour discrimination and allowing great accuracy of results.

Ability to guarantee constant lighting conditions: An optional item for the Comparator 2000+ is the Daylight 2000 Lighting Unit. This is a standardised light source which guarantees you a constant lighting condition for accurate colour grading. This is particularly useful when the sample is very pale in colour. By using a Lovibond® lighting unit, you can confident of uniform lighting conditions for colour matching, 24 hours a day and irrespective of ambient lighting.

Extended shelf life: The unique feature of Lovibond® test discs is that they incorporate coloured glass standards that are colour stable and not affected by UV light or extreme environmental conditions.
Please note, we cannot guarantee compatability of discontinued Lovibond® Comparator 1000 disks with the Lovibond® 2000+ Comparator.
