Fits in seconds
A silent, waterless indicator
Reacts in seconds
Unlike water based airlocks, the VisiBrew Indicator uses colour metric technology to instantly detect the presence of CO2 venting through the Sterilock® by turning from blue to gold.
This means the brewer can determine fermentation is occurring hours before a water based airlock vents it's first bubble and know exactly when fermentation has ceased.
Being waterless, the VisiBrew indicator can never dry out, meaning it can simply be fitted and forgotten without any risk of contamination.
Each indicator is good for a brew
Once fitted, the indicator will continue to detect fermentation for up to two weeks. That's over twice the length of an average brew.
FITS IN SECONDS
The indicators can be removed from their silicon strips and using the two-way adaptor fitted in seconds to either the Sterilock® or even the odour absorbing capsule.
A shelf life of years
Retained on their silicon strips the VisiBrew Indicators will last for years.
Small is beautiful
With the VisiBrew indicator fitted, the Sterilock® only stands a minuscule 3 cm above the fermentation lid. That's some 14cm shorter than an average bubbler type airlock.
Ideal for small spaces
This makes it ideal for brewing in cramped locations such as cupboards and brew fridges.
A SILENT, WATERLESS INDICATOR
Silence is golden
Being waterless, the VisiBrew indicator does not glug or rattle through the night, making for a quiet night’s sleep for brewer and family alike.
