HIGH RANGE DPD & PH 2000 SERIES COMPARATOR
Product Overview
Direct optical replacement block engineered for Taylor 2000 Series high-range sanitizer and pH testing.
Molded from chemical-resistant optical plastic, the Taylor 9056 comparator block features integrated color standards for high-range chlorine (1–10 ppm), bromine (2–20 ppm), and pH levels from 7.0 to 8.0. Built specifically for Taylor 2000 Series test kits, it eliminates guesswork with distinct color gradations and a light-diffusing background channel that resists fading from reagent exposure.

Benefits & What Makes It Different
Integrated Optical Standards
Permanent color gradations for pH (7.0–8.0) and sanitizer levels won't peel or flake under wet service conditions.
Dual Sanitizer Scale
Calibrated dual-scale side reads 1 to 10 ppm high-range chlorine and 2 to 20 ppm bromine on a single visual block.
Precision Molded Chambers
Fixed-volume sample cells ensure consistent water-to-reagent ratios for reliable DPD and phenol red tests.
Compatibility
- Compatible with Taylor 2000 Series test kits (including K-2005 series)
- Uses Taylor liquid DPD reagents (#1, #2, #3) and Phenol Red (R-0004 / R-0014)
When To Use This
Pro Tip
Wipe the exterior of the sample tubes completely dry before reading, and hold the block at eye level backed by indirect natural daylight against a neutral white card.
Common Questions & Instructions
When should I replace my Taylor 9056 comparator block?
Replace the block every 12 to 24 months or as soon as the clear plastic shows clouding, yellowing, or chemical staining that skews optical color matching.
Does the Taylor 9056 comparator work with both chlorine and bromine?
Yes. The sanitizer side features printed scales for high-range free chlorine (1 to 10 ppm) and total bromine (2 to 20 ppm), allowing testing across both sanitizer regimes.
How do you clean DPD reagent stains off the comparator block?
Rinse immediately after each test with clean tap or distilled water. For persistent stains, soak briefly in mild dish soap and wipe gently with a soft cotton swab; avoid abrasive pads.
