Menumaster smashes microwave interference test

Talk of commercial microwave ovens interfering with radio communications equipment, WiFi connections and even medical equipment is something that manufacturers in the sector have to contend with.

But Menumaster claims it has overcome that challenge by manufacturing its compact range of microwave ovens to a better standard than it is legally obliged to.

EMC emissions testing requirements for commercial or industrial microwave ovens demand manufacturers achieve ‘Level A’, but Menumaster has gone one step further by achieving ‘Level B’ testing.

Bradshaw, which distributes the ACP-owned brand in the UK, says that by conforming with the “much higher and more stringent” Level B testing, Menumaster is ensuring that its appliances produce minimal electromagnetic emissions.

The operating frequency of a microwave oven is 2450 megahertz, which is very close to the operating frequencies of mobile and radio communication systems.

According to Bradshaw, it has been found that some microwave ovens can interrupt communication frequencies, resulting in EPOS till systems losing data, WiFi connections being lost, mobile phone signals dropping out and some medical equipment malfunctioning.

It argues that Menumaster’s certification makes it a much better fit for hospitals, coffee shops and cafes than other brands due to the reduced possibility of interference.
