Description Vendor

This humidity sensors are capacitive thin-film polymer sensors designed for measuring relative humidity with a full measurement range of 0 ... 100 %RH and accuracy up to ±0.8 %RH. They offer excellent long-term stability, are insensitive to dust and most chemicals, and include features like chemical purge options, sensor heating, and full recovery from condensation. These sensors are known for their reliability, accuracy, and durability, suitable for a wide range of applications from HVAC to industrial environments.

Use Cases

  • HVAC
  • Industrial applications
  • Moisture measurement in oils and other liquids
  • Processes with H2O2

Capabilities

  • Accurate humidity measurement
  • Long-term stability
  • Resistance to dust and chemicals
  • Chemical purge option
  • Sensor heating for condensing environments
  • Full recovery from condensation
Vaisala Oyj Vaisala Oyj is an industrial technology supplier whose business includes moisture, humidity, and gas measurement instruments relevant to hydrogen production and handling. The broader business is instrumentation-oriented, with sensors and analyzers supplied either as stand-alone instruments or embedded into machines, process skids, safety systems, laboratories, and plant automation so operating conditions can be measured and documented. The company’s products typically provide information to a larger control, safety, quality, or test system, making measurement accuracy, response behavior, interfaces, calibration, and environmental suitability part of the integration task. For hydrogen, the company’s actual role is defined by the specific pressure, flow, gas-detection, concentration, quality, temperature, electrical, or other measurement functions described in its portfolio; different suppliers cover different parts of this measurement layer. Its high-accuracy analyzers can monitor water content and dew point in gases and process environments where hydrogen purity and drying are important. Vaisala instrumentation is used for process control, quality assurance, and equipment protection in industrial gas systems. Within the hydrogen value chain, Vaisala Oyj therefore supplies instrumentation, monitoring, or safety technology to OEMs, test organizations, plant integrators, infrastructure developers, and industrial operators handling hydrogen.
