Turbidity Test Tube

The Sentinel Turbidity Tube is a visual tool to help you judge which water treatment best practice solution is appropriate for each of your customers’ systems. Since it is a visual demonstration, you can share the results to reassure your customers that you are recommending the appropriate solution for them.

This product offers a simple and effective method to easily demonstrate the turbidity (water quality) in a central heating system. The visual method uses a series of concentric circles at the
base of the tube which are observed through a water sample from above. Water is progressively removed until the circles can be seen through the sample, permitting a quick and simple diagnosis of system water quality and an indication of what remedial action is required.
• Quick and simple on-site evaluation of system water quality
• Provides tailored water-treatment recommendations
• Robust design to withstand daily handling, usage and transportation

Method of Use
1 Circulate the system for 15 minutes.
2 From a convenient drain point, fill the tube up to, or above line A.
3 Look down the tube through the liquid for the black concentric circles.
4 If not visible, remove a small amount of water and repeat until the concentric circles are visible and note the level on the tube.
- Above line A: the system is clean.
- Between line A and B: the system is dirty.
- Below line B: the system is very dirty.
