Hands-free Clean Room Telephones for Pharmaceutical and Hospital Clients

The TLS 250 is an analogue phone, capable of working as part of any general analogue, digital or VoIP communications system, yet specifically designed for clean room applications. 

The standard unit is telephone line powered, requiring no additional power supply, and will connect as a direct replacement to any existing analogue telephone.

The units conform to IP.6.5 for water and dust protection.  

The polyester face-plate is resistant to all solvents, except for concentrated minerals, concentrated caustic solution, high-pressure steam above 100C, alcohol benzyn, and methylene chloride. Fungicides, bacteriocides and viruticides may be used.
