Melaphone Speak Thru

Melaphone is specifically designed to allow sterile communication with a high degree of vision and safety. There is no thru-air flow, therefore, no transmission of germs, draughts or dust. Speech is transmitted through a transparent diaphragm which also gives protection against noxious sprays. This gives you the ultimate insurance that both sides of the screen will be protected from any kind of transmission.

Frequently Asked Questions

How clear is communication using the unit?

The unit is designed to facilitate the exchange of information. Thanks to its sensitive diaphragm, speech is clear and there’s no need for a loudspeaker or power supply. This means that you can use the melaphone as normal without having to make any adjustments to your speech.

Does the unit affect vision?

In short, no – the unit is constructed from clear polycarbonate and, as such, vision is not impaired. Even when installed in double glazing, a transparent cylinder is used to maintain visibility. By using this kind of material you can clearly see who you are talking to and what is happening on the other side.

How secure are the units?

The unit itself demonstrates incredibly high-impact strength. They can also be reinforced using a stainless steel mesh guard and will offer effective protection and security for your staff giving you the peace of mind you need.

Can germs pass through the Melaphone unit?

Due to the specific design of the unit, there is no thru-air flow. This means that germs, and other harmful contaminants, cannot pass through the unit. This allows you to deal in an environment that is as clean as can be, protecting users on both sides of the screen.

The Melaphone is very easy to clean and maintain. They are resistant to wear and tear and, if a particular part needs to be replaced, we also offer a comprehensive range of spares.
