TESTOVAL® Colour Comparator: ORTHO-PHOSPHAT

The Testoval Phosphate Color Comparison Device is designed for fast visual determination of phosphate content in water. Measurement is performed manually via color comparison. Without the use of additional electronic equipment, concentrations from 0.25 mg/L to 10 mg/L P₂O₅ can be read directly using the color scale.

The Heyl Testoval is suitable for both routine checks and simple documentation of results.

Fast Phosphate Measurement via Color Comparison Without Equipment

The Heyl color comparison device is specifically designed for applications requiring fast results and ease of use. By diluting the water sample 1:10 with distilled water, the measurement range can be extended tenfold.

With the Testoval Phosphate Color Comparison Device, approximately 180 analyses can be performed, making it an economical solution for routine monitoring.

Typical Applications of the Phosphate Color Comparison Device

Manual phosphate determination is a proven method in many areas of water analysis, particularly where electronic measurement devices are unavailable or unnecessary.

• Environmental monitoring
• Water and wastewater analysis
• Laboratory applications

Advantages of Phosphate Measurement with the Heyl Testoval Kit

The Heyl Testoval Phosphate Test Kit offers a reliable, fast, and user-friendly way to determine phosphate content (P₂O₅) in water samples—completely without electronic devices or lab infrastructure.

1. Fast on-site results: The colorimetric measurement provides usable results within minutes, ideal for routine checks, spot measurements, and immediate decisions.
2. Easy handling without equipment: No electronic devices, power supply, or software are needed. Results are read visually via a color scale, making the device robust, error-tolerant, and easy to use.
3. High practicality and mobility: Compact design allows mobile use—in the field, at measurement points, or in operational settings. Perfect where laboratory analysis would be too complex or time-delayed.
4. Accuracy for monitoring and control: Provides practical accuracy for environmental monitoring, water and wastewater analysis, and brewing, allowing limits to be checked and trends detected early.
5. Economical and efficient: With around 180 analyses per kit, the Heyl Testoval offers a cost-effective solution for regular measurements without maintenance, calibration, or follow-up costs for equipment.
6. Extendable measurement range: Simple sample dilution (1:10) allows flexible expansion of the measurement range, increasing usability for higher phosphate concentrations.
