Magnesium Tablets for Photometers

Overview

Magnesium tablets measure magnesium hardness, normally worked out alongside calcium so that the two halves of total hardness can be separated. Magnesium matters where silica and magnesium together drive scale in boilers, and in agriculture and bottling where the ionic balance of a water is specified.

Key features

• Separates the magnesium fraction from total hardness
• 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 TbSPMag250

Frequently asked questions

How is magnesium hardness usually determined?
Magnesium is the part of total hardness that is not calcium, so it is normally reported by measuring total and calcium hardness and taking the difference, or by a dedicated magnesium test.

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.
