Photometer with automatic calibration Alyza® IQ PO4

Product overview
The Alyza IQ PO4 is an on-site orthophosphate analyzer designed for integration into IQ SENSOR NET. It performs wet‑chemical photometric measurement using the molybdate‑vanadate (yellow) method directly in the process stream. Typical uses include phosphate removal control and phosphate load monitoring.

Alyza IQ PO4
The analyzer integrates into new or existing IQ SENSOR NET installations and is installed like a sensor. Measurement is performed wet‑chemically on the sample flow. The instrument supports continuous monitoring and process control tasks.

Key benefits

• Very low reagent consumption and reduced waste, lowering operating costs
• Short routine maintenance — approximately 10 minutes every 3 months
• Accurate measurements across ranges: MR1 and MR2 (detailed ranges below)
• Automatic cleaning and selectable 1‑ or 2‑point calibration intervals for operational safety
• On‑site installation at basin edge to minimize sample transport; optional climate package for outdoor operation

Highlights

• Low reagent use and minimal waste generation
• Fast, simple service intervals
• Reliable results from low to high concentrations (MR1 and MR2)
• Automatic cleaning and calibration with standards
• Designed for on‑site installation; climate package available for all‑weather operation
