Rotronic

What Rotronic does

Rotronic AG is a Swiss-headquartered (Bassersdorf) developer and manufacturer of precision measurement instrumentation, specializing in humidity, temperature, CO2, differential pressure, water activity, dew point, and oxygen measurement. The company, founded in 1965 and operating as a brand under the DwyerOmega industrial conglomerate, serves regulated and quality-critical industries including pharmaceuticals, medical/healthcare, food and tobacco processing, HVAC and data centers, industrial manufacturing, museums/archives, and meteorology. Its core product architecture is built on interchangeable HygroClip2 digital probes featuring proprietary AirChip3000 technology, paired with the HygroFlex transmitter family (HygroFlex1, HF5A, HF73A, HF5-EX ATEX variants), feeding into the RMS cloud-based monitoring system for real-time multi-site surveillance and alarming.

The business operates a diversified revenue model across four streams: hardware sales (probes, transmitters, data loggers, water activity instruments), software and monitoring subscriptions (HygroSoft, HW5, and the RMS cloud platform), ISO 17025-accredited calibration and GxP validation services, and accessories/spare parts. Products are sold via a quote-based model through approximately 50 direct sales points across 10+ countries (Switzerland, Germany, France, Italy, UK, USA, Canada, Singapore, China, Japan), an authorized global distributor network, an online e-commerce storefront in the US, and extended reach through the parent DwyerOmega distribution umbrella. The company holds ISO 9001:2015, ISO 17025:2017, ATEX/IECEx hazardous-area, GMP/GAMP, CE, and UKCA certifications, anchoring its position in regulated verticals where compliance credentials function as procurement gates. Andreas Gähwiler serves as Managing Director of the Swiss entity, which operates alongside Rotronic Instrument Corp. (Hauppauge, NY) as the primary US subsidiary.
