Test water in a snap

With the JBL ProScan, you can easily and quickly measure the most important water values in your pond, aquarium, or tap water. Dip the test strip into the water for 2-3 seconds, place it on the special color chart, and scan with the free JBL ProScan app. Within seconds, you'll see not only the exact values, but also whether they're good, fair, or poor – plus advice on how to improve them.

The 7 measured values

• GH (total hardness) – Indicates the mineral content of the water
• KH (carbonate hardness) – Important for stable pH levels
• pH – Measures whether the water is acidic or alkaline
• Nitrite (NO₂) – Toxic to fish, indicates filter problems
• Nitrate (NO₃) – Nutrient for plants, excess causes algae growth
• Chlorine (Cl₂) – Harmful to fish and bacteria
• CO₂ (calculated) – Important for plant growth in aquariums

Works with your smartphone

The ProScan app is free for iOS and Android. Thanks to the autofocus camera, the color is measured accurately – often more reliable than the naked eye. The system provides instant optimization tips and product recommendations from JBL.
