Sulphitometers – SO₂ Gas Dosing Unit for Wineries

Accurate sulphur dioxide dosing, from a single barrel to a full tank farm

A sulphitometer lets you measure and dispense sulphur dioxide (SO₂) gas by weight, so your additions are accurate and repeatable. It suits small boutique cellars and large commercial wineries alike, with five sizes to match the way you work.

Choose your size from the variant selector:

• 300g – Compact, hand-carried unit for fine additions to small batches, barrels and lab-scale work. Very fine 2 g graduations.
• 1kg – A lightweight, portable all-rounder for barrel rooms and small tanks, with 5 g graduations.
• 3kg – Free-standing with a carry handle and a certified stainless steel pressure vessel, with 10 g graduations. A good step up for regular tank and barrel dosing.
• 10kg – Trolley-mounted on large pneumatic tyres, with both a needle valve for fine dosing and a diaphragm valve for bulk dosing. Suited to large tanks and busy vintage work.
• 18kg – The largest unit, with the same trolley, dual valves and 50 g graduations as the 10kg. Ideal for high-volume wineries dosing large volumes through vintage.
