Waltron 3146 Ammonia Analyzer

Online colorimetric ammonia analyzer for high-purity process and boiler-cycle water — OEM range 0–1000 ppb, automatic calibration/validation, dual-stream option, and the shared 314x stainless IP65/NEMA4X package.

Key advantages

Ammonia ranges — 0–1000 ppb (OEM product page / catalog).
Accuracy — ±5 ppb or ±2% of reading.
Tool-less wet end — Pre-assembled pump/sample heads; automatic calibration and validation (QA/QC).
Operator UI — Color touchscreen; USB datalogger on door; motion-sensor LED and color alarm indicators.
Enclosure — IP65 / NEMA 4X stainless; about 24×15×8.5 in (60×38×21 cm); ~17 kg; panel/wall mount.

Typical applications

Ammonia dosing for pH control in high-purity process water.
Boiler cycle water and condensate return ammonia residual.
Online colorimetric ammonia where potentiostatic options are not required.

Selection guide

Range — Choose among OEM ranges: 0–1000 ppb.
Streams — 1 vs 2 sample streams; grab-sample use.
Outputs / alarms — 4–20 mA (galvanic isolator option) or 0–5 V; 2 or 4 configurable alarms.
Cycle — OEM cycle about one reading every ~20 min, adjustable; confirm process needs.

Common mistakes

Expecting continuous analyzer speed — OEM cycle is a batch process (~12 min response; adjustable reading interval).
Pressurizing the sample into the analyzer — OEM sample pressure is atmospheric at 100–500 ml/min.
Skipping reagent / tubing maintenance — OEM cites monthly reagents and quarterly tubing.
