Bulk Pack — 50 units

Unit price: $13.99 each. Bulk pack savings for repeat-purchase lab consumables.

Ammonia nitrogen water test strips provide rapid colorimetric analysis for quantifying dissolved ammonia in aqueous samples using the established Nessler reaction methodology. These strips utilize visual colorimetric detection based on the formation of a characteristic yellow-brown complex when ammonia reacts with potassium tetraiodomercurate(II) under alkaline conditions, producing measurable color change proportional to ammonia nitrogen concentration.

The test strips cover a measurement range of 0-0.5-1-3-5-10-20 mg/L, suitable for both freshwater and seawater analysis across diverse environmental and industrial applications. The colorimetric detection principle aligns with established analytical procedures, providing field-deployable ammonia quantification without requiring specialized laboratory instrumentation or technical expertise. The portable format enables on-site water quality assessment in remote locations where traditional spectrophotometric analysis is impractical.
