Total Dissolved Solids (TDS) are the total weight of all solids that are dissolved in a given volume of water, expressed in PPM (Parts Per Million).
By using a TDS meter, you will quickly be able to determine the quality of your Reverse Osmosis water, before it passes though a Di resin vessel. A TDS meter is a vital piece of equipment if you are using a Reverse Osmosis unit with a Di resin vessel. If you are not using a TDS meter, you may be throwing away DI Resin which is perfectly serviceable. On the contrary, your DI Resin may be long exhausted, allowing contaminants onto the windows causing streaking and spotting.

Next Day Delivery
Delivery charges are applied to your order depending on weight and order value. These charges will be clearly displayed in the checkout process. To place an order through our online shop, you must be over 18 years of age, contactable by non cellular telephone, resident in United Kingdom and accessing our website from an address in the United Kingdom.
Please note, all orders must be placed by 1:00pm for next working day delivery.
We use APC couriers for next day parcel service and we can usually dispatch your order for next day delivery if you confirm your order by 1:00 pm. For large and heavy items and items that could be damaged if sent in standard parcels (including 100 metre hose reels ) we use Palletways next day tail lift service. Large floor scrubber driers and sweepers are delivered by our own specialist vehicles and operator training given at the time of delivery.
Some machines in our range are built to order, however we normally stock all the products listed on our web site and dispatch them direct from our own warehouse. The customer however accepts that not all items are in stock at all times, and in this case delivery may take longer than would otherwise be the case.
We aim to deliver all orders on next day delivery service. Customers requiring an urgent delivery are advised to ring 01491 825600 to confirm stock availability. Our usual delivery schedule is from Monday to Friday between 8:00 am and 6pm. We do cater for delivery times before 10:30 and 12:00 am but this is at an extra cost.
Specific delivery days, including Saturdays, and alternative delivery addresses can be accommodated but these are also subject to additional carriage charges.
