Measurement solutions for the coronavirus pandemic

Vaisala solutions are making a significant contribution to the fight against the COVID-19 pandemic. While our larger mission is to support the United Nations Sustainable Development Goals for Good Health and Well-Being, our immediate goal is to provide measurement instruments and systems that support safe vaccine production and distribution, bio-decontamination, storage applications, and more.

Humidity and Temperature Probe HMP1 for wall mounting

Vaisala HUMICAP® Humidity and Temperature Probe HMP1 is designed for measuring ambient measurement in indoor spaces. HMP1 can be directly connected to Indigo200 series transmitters to form a single wall-mounted unit. Its probe head and body are integrated to a single unit and it uses the miniature 5 mm (0.2 in) diameter HUMICAP® sensor and head for great stability and fast response time.

HMP1 is part of the Indigo product family and compatible with Indigo200 and Indigo500 Series Transmitters. HMP1 can also be used with the Vaisala Insight PC Software for data visualization, easy probe configuration and self-calibration.

  • Probe for wall mounting when combined with Indigo series transmitters
  • RH accuracy up to ±1 %RH and temperature accuracy up to 0.2 °C (0.36 °F)
  • Temperature measurement range -40 … +60 °C (-40 … +140 °F)
  • Chemical purge provides superior chemical resistance
  • Modbus RTU over RS-485 for flexible connectivity
  • Includes a traceable calibration certificate: 6 points for humidity, 1 point for temperature


Vaisala have two global business areas that develop, manufacture and market innovative products and services for environmental and industrial measurement.

Weather and Environment Business Area

Serves selected weather-dependent markets where accurate, real-time, uninterrupted, and reliable weather data is essential to run efficient operations.

Industrial Measurements Business Area serves

Industrial customers in life science, power transmission, and targeted industrial applications. It offers a broad range of measurement instruments to ensure operational quality and productivity.

Innovation and technology are cornerstones for Vaisala’s success and we keep advancing the art of environmental observations. Technological innovation is in our DNA, and want and need to be at the cutting edge of development, to find new solutions to customer needs in demanding applications.
