Stevens Weather Sensors and Stations
Weather conditions are often an integral element in water resource and irrigation management applications. Weather parameters are frequently used in understanding and modeling environmental applications that are dependent on water resources. Stevens provides top quality and industry leading weather sensors that are easily deployed into an integrated environmental monitoring and control system.
Precipitation GagesStevens Water carries a number of precipitation gages, from highly accurate weight-based systems to simple tipping buckets for remote monitoring applications. For a full list of available rain gages, please see our complete rain gage list. 
The Tipping Bucket Rain Gage is a WMO recognized standard for measuring precipitation in remote, unattended locations designed with a siphon system for improved accuracy, especially during high rainfall events. 
The Met One Instruments 370 Series all-metal precipitation gage measures rain and/or snow in all environments using a tipping bucket mechanism. The economical tipping bucket design allows accurate, repeatable measurements, requiring no regular maintenance. Met One Model 380 Rain Gage with 12 Inch Catch 
The Met One Instruments 380 Series precipitation gage features an expanded 12" catch for accurate rain measurement, even in remote locations. The 380 Series precipitation gage exceeds EPA specifications for precipitation monitoring, and is available in three calibrations: .01 in., 0.2 mm, or 0.25 mm. OTT Pluvio² Precipitation Gauge 
Recognized worldwide for its precision and performance, the OTT Pluvio² is an all-weather precipitation gauge that uses superior weight-based technology to measure rainfall, snow or hail. |
Weather StationsWeather stations are an easy way to add monitoring of rain and atmopsheric conditions such as temperature, pressure, and humidity to any station or site. Stevens weather stations ship pre-assembled and are ready to deploy right out of the box. Vaisala WXT520 Compact Six-Sensor Weather Station 
The Vaisala WXT520 is at the cutting edge of miniaturization technology, offering six sensors in one instrument: Wind Speed, Wind Direction, Rain Fall (and Hail), Barometric Pressure, Temperature and Relative Humidity. Combined with the Stevens DataLogic 3000 data logger, The Vaisala WXT520 is a complete weather monitoring station that can easily be configured with other sensors and with wireless communications. CM-100 Compact Five-Parameter Weather Sensor 
The CM-100 Compact Weather Sensor is an all new weather measurement system, offering five of the most popular parameters in an space-efficient package than can be mounted almost anywhere. The CM-100 Compact Weather Sensor features no moving parts, increasing longevity of the sensors and reducing maintenance issues. The CM-100 measures temperature, relative humidity, wind speed, wind direction, and barometric pressure in a single compact, rugged unit. Met Station One MSO Five Parameter Weather Station 
The new Met Station One (MSO) weather station combines five of the most popular meteorological measurements into one simple, economical package, allowing for efficient and accurate comprehensive weather monitoring to be added to any existing site or new installation. The MSO features wind speed, wind direction, temperature, relative humidity, and barometric pressure sensors. |
Wind Speed and Direction SensorsMet One Ultrasonic Wind Direction & Speed Sensor 
The Met One Ultrasonic Wind Direction & Speed sensor is highly accurate with no moving parts, which eliminates required maintenance common to mechanical sensors. This 16-point wind tunnel calibrating sensor provides digital and analog outputs. Available in heated option. RM Young 5103 Wind Speed & Direction Sensor 
The RMY Wind Speed & Direction sensor is a high performance, rugged time proven design ideal for a wide range of wind measuring applications. The wind speed sensor is a four blade helicoid propeller. Propeller rotation produces an AC sine wave voltage signal with frequency directly proportional to wind speed. Slip rings and brushes are eliminated for increased reliability. The wind direction sensor is a rugged, yet lightweight vane with a sufficiently low aspect ratio to assure good fidelity in fluctuating wind conditions. 
The Met One Wind Direction Sensor provides azimuth data for use in micrometeorological measurements related to operational studies and research. This sensor is especially useful when a low starting threshold, a high damping ratio or a short delay distance is required. Met One Wind Speed and Direction Sensor 
The Met One Wind Speed and Direction Sensor combines wind speed and direction measurements into a single sensing unit. The unit installs in minutes and will provide accurate, long term, continuous monitoring in hostile environments. The sensor is designed to operate within a temperature range of -30° to +70° C and withstand wind speeds up to 167 mph. |
Relative Humidity and Barometric Pressure SensorsVaisala HMP155 Relative Humidity & Temperature Sensor 
The Vaisala HMP155 humidity and temperature probes are designed for a wide range of instrumentation e.g. recorders, data loggers, laboratory equipment and weather stations. Operating range is 0% to 100% relative humidity and -80 to +60°C. Met One Relative Humidity and Temperature Probe 
The Met One Relative Humidity probe represents sensitivity, accuracy, linearity and stability not encountered with conventional relative humidity sensors. It is extremely well suited for meteorological, industrial, laboratory and other demanding applications. Met One Barometric Pressure Sensor 
Barometric Pressure Sensors convert absolute atmospheric pressure into a linear, proportional voltage, which may be used in any meteorological program. The Met One barometric pressure sensor brings in modern digital computer technology. An on board CPU scales pressure measurements, provides temperature compensation and controls communications output. |
Air Temperature SensorsNovalynx Air Temperature Sensor 
The NovaLynx Air Temperature Sensor is designed for accurate measurement of ambient air temperature in outdoor environments. Accurate to +/- 1.5°F over the full 0-120°F range. The sensor does not require any external calibration or trimming. |
