The Essentials Lab Test provides the core analysis needed to understand the condition of your closed-loop water system. It covers fundamental checks including pH, conductivity, iron, and suspended solids, helping to identify the most common issues that can affect system health and efficiency.
Please note: all samples must be returned by post at the customer’s own cost. This is not included in the test price.
| Essential Lab Tests | Purpose |
| Glycol concentration | Checks antifreeze levels and protection against freezing |
| pH | Measures acidity/alkalinity of system water |
| Conductivity | Assesses ion concentration – high levels indicate contamination or over-treatment |
| Iron (soluble and total) | Detects corrosion activity, pipe or component wear |
| Aluminum | Identifies corrosion risk in aluminum components |
| Phosphate (ortho) | Monitors levels of phosphate-based corrosion inhibitors |
