Sigrist-Photometer AG with a new market presence

A new logo adorns the Sigrist brand on the outside. But Sigrist has also been equipped with a new value proposition and brand values at the core of the brand in order to make an even greater impact on the market.

Sigrist-Photometer AG appears with a new corporate identity

For over 75 years, the brand "Sigrist-Photometer" has been standing for high Swiss quality and innovative strength in the process photometry industry. Just like the products, the brand's image has been firmly anchored for decades.

But the market is on the move, and with an eye to the future, Sigrist-Photometer AG has decided to revamp the brand's appearance. The appearance of a brand can be derived from the corporate values. In an internal process, new brand values were created and from them the new corporate identity. Sigrist now presents itself with a new logo, new colours and modern corporate communication. In future, the new image will also have an impact on the product range. On the one hand in the visual appearance, the housing design and improved user-friendliness, and on the other hand in the inner workings, where research continues into sustainable, efficient and absolutely precise technology. This is our daily drive, our motivation for a strong Sigrist brand.

Thus, from September 2022, the Sigrist brand will shine in new splendour and give the company as well as the employees a motivating boost for a successful future.

New brand values and a clear core value proposition

A brand is only as good as its core values. Today, successful brand management is more than just an attractive external appearance. Brands should be tangible, for customers as well as for employees.

For this reason, the brand was completely redefined when the new corporate identity was developed. The core service promise and four brand values form the cornerstones of the company - as a manufacturer brand as well as an employer brand.

"With our intelligent measuring systems, we guarantee safety, sustainability and cross-linked processes." This core value proposition is considered a clear statement on the market and is intended to lead employees even closer to the brand as well as recommend them to become strong brand ambassadors.

In addition, four brand values complement the company's clear goals and are also daily incentives for the many skilled and talented employees at Sigrist-Photometer AG.

  • Progress - We are already thinking about tomorrow in order to continuously improve ourselves and our products.
  • Partnership - We build on trusting relationships to achieve relevant goals together.
  • People - We are Sigrist. We are smart. (social, motivated, agile, relevant, team-oriented).
  • Responsibility - We take responsibility for people and the environment with our measurement systems.

Giving new colours

With its new corporate colours of dark blue and turquoise, Sigrist stands for trust, safety and responsibility as well as for creativity, activity and environmental awareness. The blue pays homage to the origins of the Sigrist brand and stands for the traditionally grown values that we still represent today. The turquoise brings a freshness to the design that emphasises our forward-looking attitude.

And where does the customer and partner come into play? With the new, fresh appearance, the "Sigrist" brand is clearly taking big steps into the future - and taking the customers with it with this market power. As already anchored in the brand value "Partnership", we at Sigrist-Photometer AG want to achieve relevant goals together with our partners. And we can only do this if we collaborate.

We are fans of our own company and brand - and look forward to continuing this path with you.

Berliner-Kindl-Schultheiss-Brewery / Germany

In 2015, the Berliner-Kindl-Schultheiss-Brewery decided to modernize the young beer separator which has three turbidity measuring points (at the inlet, at the outlet, in the bypass). The goal was to incorporate reliable, low-maintenance turbidimeters. Those should guarantee optimum operation of the separator as well as allow a comparison of in-line and laboratory measurements.

Sigrist turbidimeters TurbiGuard were chosen, with a connection to the control unit SICON M. These instruments supply EBC turbidity values which can be compared with those measured in the laboratory and cover a measuring range of up to 1000 EBC. This ensures smooth operation of the separator particularly during turbidity peaks from fresh fermentation tanks. Sigrist TurbiGuards hardly need to be serviced.

The Berliner-Kindl-Schultheiss-Brewery was able to significantly reduce maintenance expenses at the separator during the first year.

Water supply Bern / Switzerland

In July 2012, the Bern water supply planned to monitor the water from the groundwater well Kiesen (output 30'000 - 40'000 l/min) for turbidity and SAC 254 (UV absorption) using Sigrist instruments.

In December 2012, the turbidity monitor AquaScat 2 and the absorption measuring instrument ColorPlus 254/700 nm were taken into operation.

The quality of the groundwater is very clean with a constant turbidity of 0.008 FNU. A parallel measurement with a second Sigrist turbidimeter AquaScat 2, carried out in January 2013, confirmed the very low turbidity value. Sigrist photometers are capable of handling even such low turbidity values in a reproducible manner.

In July 2015 Sigrist received a follow-up order by the Bern water supply for three AquaScat 2 WTM-A instruments and one ColorPlus 254/700 nm.

Road tunnel Gotthard / Switzerland

Since September 2007, a total of 210 Sigrist smoke detectors of the type FireGuard are in use in the Gotthard tunnel and its approach tunnels. Together with additional sensors such as linear fire alarm cables, flow measurement devices etc., the smoke detectors are the basis for the early detection of smoke and fire events.

In September 2016, after a period of use of 9 years, Mr. Werner Furrer, head of the Office for the Operation of National Roads (Switzerland), summarized their experience with the FireGuards as follows:

  • On average, there was one event per month, which was detected without fault
  • In a smoke event, the FireGuard is always the fastest system
  • No false alarms owing to correct parameterisation

»We have had no failures so far. Sigrist FireGuard smoke detectors are very reliable.«
