Helvetas Water Project 2019


Continuing one of Swans traditions, Swan is supporting a further Helvetas drinking water project. This year the project is in Nepal, Helvetas first partner country. Since the beginning of this specific water project in 2001, 442 facilities for clean drinking water have been built and over 150,000 people in 25,000 household have benefited from sanitary facilities and an improved drinking water supply. The aim of this project is to further educate the locals about the proper water handling, basic hygienic rules and how to prevent diseases as well as to continue to provide easy access to clean drinking water. By working with Helvetas for many years, we can guarantee that our donations are being used properly. 

Swan thanks you for your continuous support throughout the years. Furthermore, Swan wishes you and your family a joyous holiday season and all the best for the next year.  

Chematest 30 & 35: Portable Photometer with Digital Sensor Connections


Chematest 35 provides the same photometric excellence as Chematest 30 and adds digital sensors connections, enabling pH and redox potential measurements.

Sharing the same menu-based platform guarantees the user-friendliness known from Chematest 30 and the AMI monitors. Every photometer is calibrated individually and its light source traceable to NIST standards. Traceable verification kits and glass cuvettes additionally assure reliable and safe utilization.  

The IP 67 waterproof design, its long-living, rechargeable Li-Ion battery and the large internal data storage are just a few of the beneficial highlights this all-rounder for users with highest demands has to offer.
