WEATHER STATION The design of the MetPak RG allows all measurements to be as accurate as possible without influencing other measured parameters yet provides a complete, compact, reference quality system. In addition to the rain gauge parameter the MetPak RG utilises the Gill WindSonic ultrasonic technology to measure wind speed and direction and a highly accurate barometric pressure sensor is housed within a vented enclosure. Temperature and humidity are measured using a Rotronic Hygroclip HC2-S3 temperature/humidity probe contained in a naturally aspirated radiation shield. The unit is especially suitable for harsh or marine environments. The MetPak RG weather station is supplied with digital SDI-12, RS232 & 422 outputs. The serial data output is ideal for interfacing with a WS-15A Display Unit. Data from the MetPak RG can be stored using the SpaceLogger.W10 (WindLogger) and SpaceLogger.W8.Wireless data loggers providing a compact affordable logging solution for long term data collection. Low power consumption enables this weather station instrument to be used in remote locations where power is at a premium.An electrical junction box is fitted to the mounting bracket allowing convenient termination of all electrical cables Wind Speed & Direction Temperature Humidity Barometric Pressure Dew Point Precipitation SDI -12 Output Gill ASCII Output Specifications: Wind Measurement: Sensor: WindSonic ultrasonic; Parameters: Polar Wind Speed & Direction or U & V Vectors Wind Speed: Range: 0-60m/s (134 mph); Accuracy: ± 2% @12m/s; Resolution: 0.01 m/s (0.02 mph): Threshold: 0.01 m/s (0.02 mph); Units of measure:m/s, knots, mph, kph, ft/min Wind Direction: Range:0 to 359 degrees – no dead band; Accuracy: ± 3° @12m/s; Resolution: 1° Air Temperature: Sensor: Rotronic HygroClip model HC2-S3; Sensor type: Pt100 1/3 Class ; Range: -35°C to +70°C; Accuracy: ± 0.1°C; Resolution: 0.1°C (0.1°F): Units of measure: °C, °F or K.
