Controlling ducting deposits and monitoring their build-up is essential to maintain hygiene standards and reduce fire risks in heating and ventilation systems.
Both the Elcometer 355 and Elcometer 456 Duct Deposit Measuring Systems have been specifically designed to perform the Duct Deposit Test in the Heating and Ventilation Contractors’ Association Guide to Good Practice, HVCA TR/19, for the measurement of dust and grease deposits within ventilation systems and kitchen ducts made of ferrous metals.
The difference between the systems is accuracy. The Elcometer 355 Duct Deposit Measuring System is accurate to ±1% or 1µm, whichever is the greater, whilst the Elcometer 456 System is accurate to ±2.5% or 2.5µm, whichever is the greater.
