Sulphite HR No. 1 Tablets for Photometers

Overview

Sulphite HR No. 1 tablets measure sulphite, the oxygen scavenger dosed into boiler feed water to mop up the last traces of dissolved oxygen before they pit the tubes. Holding a sulphite residual in the boiler is the routine proof that the scavenger dose is adequate.

Key features

• Confirms the oxygen scavenger residual in boiler feed and boiler water
• 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 TbSHSULFHR1250

Frequently asked questions

Why hold a sulphite residual?
A residual proves there is scavenger left over after all the dissolved oxygen has been consumed. Without it you cannot tell whether the dose was sufficient or merely close.

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.
