Total Hardness LR Tablets (TC Method)

Overview

Total hardness LR tablets measure the combined calcium and magnesium in a water, the figure that decides whether a system will scale and whether a softener is doing its job. On boiler feed and cooling circuits hardness is watched continuously, because carbonate scale on a heat transfer surface costs fuel long before it causes a failure.

Key features

• Reads total hardness as calcium and magnesium together
• One tablet per test, so there is no measuring or decanting of liquid reagents
• Foil-sealed strips keep unused tablets dry until they are needed
• Supplied in the standard 250-tablet pack, item code TbsRTHLR250

Frequently asked questions

Can I use this to check a water softener?
Yes. A softened stream should read close to zero hardness, and a rising figure is the usual sign that the resin needs regenerating or the media is exhausted.

Photometer grade or rapid grade — which do I need?
Photometer grade is formulated for instruments that read a cuvette. If you work with a visual comparator or colour disc, ask us for the rapid-dissolving grade instead.

How should the tablets be stored?
Keep them sealed, cool and dry, and work through the oldest strip first. Once a strip is opened the tablets take up moisture, so use them promptly.
