MI70 Hand-held meter

The Vaisala Measurement Indicator MI70 is a user-friendly indicator, and when combined with a measurement probe it is ideal for field checking and calibration of Vaisala's fixed instruments. The MI70 has probes for measuring humidity and temperature, dewpoint, moisture in oil and CO2. In addition, the MI70 can be used as a display when connected to certain Vaisala transmitters.

Humidity instruments

A comprehensive assortment of instruments for measuring relative humidity in almost any combination of temperatures, pressures, and humidity levels. There is a Vaisala HUMICAP® instrument for the most demanding application as well as the most routine.

Barometric pressure instruments

Accurate and stable barometers encompassing OEM and fully configurable, multi-parameter instruments for laboratory or meteorological applications. The heart of each barometer is a silicon micromachined Vaisala BAROCAP® absolute pressure sensor.

Carbon dioxide instruments

CO2 instruments and modules with ranges from ppm levels to 20% with a variety of configurations suitable for HVAC, ecological, and incubator measurements. Patented Vaisala CARBOCAP® NDIR sensors have a built-in reference measurement, providing superior long term stability.

Dewpoint instruments

Covering a wide range of dewpoint and process temperatures with fast response time and little long term drift. Vaisala DRYCAP® dewpoint instruments are used for measuring compressed air, furnace gas, drying processes, and more.

Moisture in natural gas instruments

Intrinsically safe instruments with interchangeable probes for measuring moisture content and temperature in natural gas. Different probe configurations facilitate sampling or direct insertion.

Moisture in oil instruments

Provide continuous, real-time measurement of moisture in oil. Suitable for use in lubrication, hydraulic, and transformer oils. Water activity output is a direct measure of oil quality, regardless of the age or condition of the oil.

Oxygen analyzers

Percent oxygen in a gas is measured using a compact tunable diode laser (TDL) gas spectrometer. Vaisala SPECTRACAP® oxygen analyzers are the first field instruments to use this technology. Configurations for in-situ measurement or extractive sampling are appropriate for inerting, fermentation, and oxygen deficiency monitoring.

Vaisala Weather Transmitter WXT520

The Vaisala Weather Transmitter WXT520 measuring the six most essential weather parameters (wind speed and direction, liquid precipitation, barometric pressure, temperature, and relative humidity) in one fully integrated instrument with no moving parts. WXT520 replaces WXT510. Applications include weather stations, dense networks, buildings, golf courses, marinas, harbors, and hotels.

Wind sensors

Ultrasonic wind sensors set the standard for wind measurement accuracy and reliability in all climates. A three-transducer layout provides superior performance in all wind directions.
