Waltron 3148 Dissolved Iron Analyzer

Online colorimetric dissolved-iron analyzer for clean water corrosion surveillance — OEM ranges 0–250 ppb, 0–500 ppb, and 0–5 ppm, automatic calibration/validation, and grab-sample capability on the 314x platform.

Key advantages

Dissolved iron ranges — 0–250 ppb; 0–500 ppb; 0–5 ppm (OEM product page / catalog).
Accuracy — ±2% of full scale.
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

Corrosion monitoring via dissolved iron in steam and boiler systems.
Automating bench iron tests with online colorimetric results.
Early detection of iron concentration changes in clean water.

Selection guide

Range — Choose among OEM ranges: 0–250 ppb; 0–500 ppb; 0–5 ppm.
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.
