PMI20 Digital Barometer Display  - NO LONGER AVAILABLE -
PMI20 can simultaneously show various values, such as the barometric pressure, the pressure trend and the WMO pressure tendency code.
Ideal for manned weather stations and laboratories. It has both an RS232 and an RS485 connection to the barometer and PC.
Moreover, as the RS485 allows a distance of up to one kilometer between the barometer and the display, the display may be used as an in-house remote display to a barometer installed outdoors.    Five open collector -type control outputs are offered with the display.

The display is compatible with all Vaisala's current barometers with a serial output as well as with the PTU200 Transmitter.

SPH10/20 Static Pressure Heads
Vaisala's static pressure heads are designed to minimize the errors in barometric pressure measurement caused by variations in wind speed and direction.

PTU200MIK1 Outdoor Installation Kit
PTU200MIK is a high-quality mounting kit for outdoor use of PTU200. It allows meteorological measurements to be made on site, e.g. next to a GPS antenna.

Humidity & Temperature - Vaisala The HUMICAP TM Humidity Sensors used in Vaisala probes give accurate and reliable relative humidity readings in harsh environments. Operation up to +180°C (some probes) Pressures up to 10MPa Negligible hysteresis Long term stability is excellent Insensitive to dust & dirt, as well as to most chemicals. The only effect of dust or oil films is to slow the response time slightly. Response time (to 90% final rdg.) after a step change from 0% to 75% RH: 2 sec (no filters & >20°C); 5 sec for HMP 45, etc. 12 or 14 sec (12mm membrane or sintered filter.) No need for re-calibration HUMITTER® incorporates Vaisala's revolutionary fully interchangeable INTERCAP® Sensor. Because of this feature they never need re-calibration. Instead, the user can easily replace the INTERCAP® Sensor without the expense and inconvenience sometimes associated with the calibration process. And, the sensor’s membrane filter/mechanical housing protects it from dust and dirt.   Humidity Instruments      Humidity transmitters for fixed installations      Portable and hand-held humidity meters      Humidity probes and OEM modules      Calibrators      Accessories

WS425 F/G Vaisala WINDCAP® Ultrasonic Wind Speed and Direction Sensor

The Vaisala WINDCAP® Ultrasonic Wind Sensor WS425 F/G is a premium, ice-free sensor for measuring surface wind speed and direction.
The sensor has no moving parts and it is resistant to contamination, salt, dust, and corrosion. Thus, the WS425 F/G requires no on-demand or periodic maintenance. The sensor has a heating feature with a total heating power of 150 W.
Wind speed can be measured up to 165 knots with the sensor.

The WS425 F/G uses ultrasound to determine horizontal wind speed and direction. The measurement is based on transit time, the time it takes for the ultrasound to travel from one transducer to another.

The transit time is measured in both directions for each pair of the transducer heads. The wind measurements are calculated in a way that completely elimates the effects of altitude, temperature, and humidity.
The WS425 F/G is especially suitable for use in harsh, arctic or antarctic conditions.
The United States National Weather Service has chosen to replace the mechanical sensors used in the Automated Surface Observing System with the WS425 F/G.

Measure rainfall precipitation with the WXT520.
The measurement is based on the unique Vaisala RAINCAP® Sensor, which detects the impact of individual rain drops.
The signals exerting from the impacts are proportional to the volume of the drops.
Hence, the signal from each drop can be converted directly to the accumulated rainfall.
The Vaisala RAINCAP® Sensor is the only maintenance-free precipitation sensor on the market.
