PTB Approval for Noise Monitoring Instruments
The Optimus sound level meter has been a symbol of simplicity and effectiveness in noise monitoring since its introduction in 2009. Its successor, the Optimus+, launched in 2018, brought with it enhanced features such as built-in Bluetooth and a redesigned keypad with ergonomic improvements.
Extensive testing of the Optimus+ sound level meter, equipped with the latest firmware, has now resulted in the highly sought-after PTB Approval. This certification ensures the instrument’s reliability and trustworthiness for users worldwide.
Additionally, the Optimus+ sound level meter holds LNE approval, further confirming its precision and reliability.
Similarly, the Trojan Noise Nuisance Recorder, developed in collaboration with housing associations, environmental health officers, and local councils, has also received PTB Approval, affirming its user-friendliness and data integrity for both professionals and end users.
What is PTB Approval?
The Physikalisch-Technische Bundesanstalt (PTB) is the German Metrology Institute, recognised as one of the world’s most esteemed national test laboratories.
Pattern Approval, also known as Type Approval, is a process where a test laboratory, such as PTB, rigorously assesses an instrument against a set of standards to ensure that it meets the manufacturer’s performance claims.
