Gerald Gobert founded the Gallwey Chemical Co. Ltd in Deptford, South London.


By this time, it was understood that the moisture content of timber prior to treatment was critical to the performance of the preservation process. Gerald Gobert built the first moisture meter to assess the moisture level of timber. He called this instrument Protimeter. As others learned of the technology, primarily building owners, they thought it would be a useful tool for resolving dampness-related disputes with tenants. With that, the market for building inspection moisture meters was created, and Protimeter Ltd was incorporated to make and sell moisture meters.


Advanced Sensors, including Protimeter, was sold to Amphenol Corporation.


Protimeter continues to lead the industry with innovative, dynamic and high performance products, selling globally through a reputable distributor network.
