Cooling System Water Testing

To keep on top of cooling system treatment and ensure a good balance of chemistry it is important to frequently test your cooling water and make adjustments to chemical dosing, bleed, redox and other parameters.

Feedwater can supply all the equipment & testing supplies you require to monitor your cooling tower, we can also provide sample kits so you can send us your cooling water sample to analyse in our chemistry laboratory.

What We Supply

  • Photometers & Tablets
  • Comparator Disc Sets & Tablets
  • Dropper Titrants & Reagents
  • Testing Meters
  • Sample Kits – Return to lab for analysis

Recommended Cooling System Testing:

  • pH
  • Total Hardness
  • TDS
  • Calcium Hardness
  • Conductivity
  • Chloride
  • Chlorine/Bromine
  • M. Alkalinity
  • Coolguard / Bromgard – This test is for Feedwater chemical, talk to us if you have different chemical products.

If you need advice about what to test for or the control limits to set for your cooling system perhaps arrange for a visit by one of our regional consultants, they can advise on efficient operation, Legionella control, recommended chemical treatment and what to measure to keep on top of cooling water chemistry.

Photometer Supplies

A Photometer is a device that reads chemical levels by passing light through a cuvette filled with the sample liquid and a crushed reagent tablet. The reaction between the tablet and the chemical present in the water change the colour of the water, the level of the chemical in the water usually determine the strength of the reaction colour.

You start using a ‘blank’ (cuvette with unreacted sample) measuring this the photometer sets a baseline for the water clarity, secondly, you enter the reaction cuvette and will receive a measurement of that specific chemical level.

Comparator Supplies

Contour colour comparators are similar to Photometers except they rely on a visual comparison using a colour disc to match the colour strength and determine the chemical level. In the same way, they use crushable tablets which react with the chemical in the sample being measured.

The Comparator kit is a more cost-effective option to the Photometer especially if you only need a couple of different comparators. Each comparator kit includes an instrument with chemical-specific petal disc, cuvettes, tablet crushers, brush and a batch of tablets. Once the tablets have been used up refills can be orderded.

Chlorine LR 0-5mg/l Comparator Kit

£75.00 exc. VAT

This product is suitable for testing chlorine at low levels of 5ppm and under.

If you are testing drinking water typical levels should be below 0.5ppm, this may have increased if the utilities are carrying out works nearby.

Swimming Pools typical treat up to 3ppm.

If you suspect the chlorine levels are higher, for example if you are performing a tank disinfection please see the 0-50ppm or 250ppm comparator kits.

1mg/l is equal to 1ppm as the terms are interchangeable.

Further product details are below.

Titrants & Reagents – Dropper Test Kits

The bulk of your boiler analysis will be performed using dropper titrants which usually involves an indicator (in liquid or tablet form) which colours the sample and then a titrant which will gradually react with the sample until it changes to a new colour. Counting the drops you can then calculate the chemical level in the sample.

This section includes:

  • Dropper Kits
  • Hardness Tablets
  • Universal pH Strips

We can supply laminated instruction sheets with our dropper test kits and some products will have demonstration videos you can view to get an idea of how it works on the product pages.

Other Products

For measuring Condustivity you will require a Conductivity meter, we also offer the service of analysing your Cooling system water in our chemistry lab, you can order a sampling kit below and be sent out a bottle to fill and return free post.
