Rotronic | Measurement Solutions (DwyerOmega)



Rotronic is a world-renowned Swiss brand specializing in high-precision measurement instrumentation for relative humidity, temperature, carbon dioxide (CO₂), differential pressure, and water activity. Founded in 1965, the brand operates as part of the broader Process Sensing Technologies (PST) group and has recently integrated its distribution and product focus alongside DwyerOmega.
Core Measurement Parameters
Rotronic equipment is heavily utilized across strict regulatory domains like pharmaceuticals, healthcare, food processing, and HVAC. They specialize in:
  • Humidity & Dew Point: Industry-leading capacitive sensors providing highly accurate relative humidity assessments.
  • Temperature: Dedicated PT100 probes, industrial transmitters, and loggers for cold chain and warehouse stability mapping.
  • Water Activity (aw): Essential laboratory analyzers and portable meters determining product stability and shelf-life.
  • Gas & Pressure: Ambient CO₂ monitors alongside precise cleanroom differential pressure transmitters.
Flagship Hardware & Systems
  • Rotronic Monitoring System (RMS): A modular, real-time continuous environmental monitoring network. It integrates hardware loggers with web-based software to comply with FDA 21 CFR Part 11 and GAMP5 guidelines.
  • HygroClip2 / HC2A Probes: Highly accurate interchangeable digital probes that form the foundation of their humidity and temperature line.
  • HygroPalm HP32: A rugged handheld instrument used for spot-checking or field data logging of environmental calculations.
  • HygroGen2: A portable, automated calibration chamber used widely for on-site relative humidity probe validation.
Are you looking to install a complete regulated facility monitoring solution (RMS), or do you need a specific handheld probe for field spot-checks?
