The CHEMetrics® C-1510 Ammonia Nesslerization Flat Comparator is designed for use with K-1510 and K-1520 series test kits and R-1501 Ammonia CHEMets® Refill (Nesslerization) ampoules. Its calibrated color standards provide visual comparison across multiple ammonia ranges for drinking water, clean surface water, nitrified wastewater effluent, and seawater or saltwater applications.

The redesigned comparator offers improved durability and consistency, along with refined color matching to better match live CHEMets® ampoules and support accurate readings. The C-1510 replaces multiple discontinued C-1510 and C-1501 comparator models while remaining compatible with existing CHEMetrics® kit cases. Refer to the instructions included with your test kit to select the correct scale.
