Anodised coating protects Sigrist optical measurement devices
18.08.2022
The optical measurement devices made by Sigrist-Photometer AG have been used to monitor processes in water treatment, the food industry, industrial processes, transport and the environment since 1946. The process photometers measure clouding, impurity concentrations and smoke in street tunnels. Continuous measurements can save resources in potable-water treatment, for example, and ensure limit values are reliably upheld.
The many different areas in which the Sigrist measurement devices are used mean the devices need to be made from robust, durable components. BWB thus anodises the aluminium components with an extra-matte finish, and dyes them either blue or black depending on where they are going to be used. In addition to protecting against abrasion and corrosion, the surface is also light-absorbing, thereby preventing distorted measurement readings.
'Having a regional partner is hugely important to us when it comes to refining our aluminium components. The fact that we have a reliable partner in BWB-Betschart AG, located only 7 kilometres away from us, is a stroke of luck', says Ruedi Tschanz, head of production. The proximity means Sigrist is able to save on time, money and CO2 emissions.
