Sigrist

Optical Measurement Solutions for Reliable Process Insight

When your process depends on detecting small changes in turbidity or phase transitions, measurement stability becomes critical.

Sigrist provides optical instruments that give you reliable data – even in demanding and fluctuating process conditions.

Get reliable measurements where accuracy and uptime matter most

In many processes, even small measurement deviations can lead to product loss, unstable quality, or unnecessary process adjustments.

Sigrist’s optical instruments are designed to give you consistent insight into your process. This allows you to respond to changes in time, maintain stable operation, and reduce uncertainty in your decisions.

A trusted Swiss manufacturer of optical measurement technology

When you work with optical measurement in critical applications, long-term stability and hardware quality are not optional.

Sigrist-Photometer AG has developed and manufactured optical measuring instruments in Switzerland since 1946. Their solutions are widely used in demanding industries such as brewing and beverage production, where measurement reliability directly impacts product quality and process performance.

You gain access to proven measurement technology designed for continuous operation in real process environments.

Technologies that give you full control of liquid processes

Sigrist solutions cover key measurement needs across process industries:

Turbidity measurement – so you can monitor clarity and filtration performance
Phase separation monitoring – allowing you to detect product transitions in real time
Color measurement – supporting consistent product quality
Oil-in-water measurement – helping you monitor discharge and environmental impact
Dual-angle optical measurement – providing deeper insight into complex liquids

Built for your applications – from breweries to industrial processes

Sigrist instruments are used in applications where reliable measurement directly affects performance and quality:

In breweries, you can follow filtration performance, control yeast dosing, and detect phase transitions before they lead to product loss
In beverage production, you can ensure consistent product quality through stable turbidity and color measurement
In industrial processes, you can detect phase changes and monitor liquid properties in real time
In water treatment, you can measure turbidity levels to support compliance and process control
In environmental applications, you can monitor oil-in-water and other critical parameters

Why reliable optical measurement makes a difference in your operation

With the right measurement approach, you gain more than data – you gain control over your process:

Stable and accurate data so you can make decisions based on actual process conditions
Reduced product loss because phase transitions are detected at the right time
Low maintenance requirements as robust, seal-less designs reduce wear and service needs
Long service life through high-quality optical components designed for continuous operation
Improved process efficiency by allowing you to respond to changes as they occur
Easy integration into your existing control system through standard communication interfaces
