METEOROLOGICAL STATION WS-2300

For applications where a reasonable price is the most important factor we offer a simple meteorological station WS-2300. In the devices introduced the temperature measurement error does not exceed 1 °C and the humidity error 5%. These indicators do not have checking certificates. 

Characteristics:

• weather forecast for the next 12 - 24 hours,
• three graphic symbols that characterize the weather,
• relative/absolute atmospheric pressure measurement in hPa and in mmHg with a calibration function: sea level, height above sea level,
• display of the atmospheric pressure trend changes,
• alarm function warning against storm and frost,
• possibility of setting an individual bio alarm,
• clock synchronized with a radio signal DCF-77,
• manual clock setting function,
• possibility of choosing a second time zone (+/- 12 hours),
• calendar,
• alarm clock,
• internal and external temperature displayed in degrees Celsius (°C) or in Fahrenheit (°F),
• dew point temperature calculation,
• man perceptible temperature calculation,
• internal/external air relative humidity measurement (RH%)
• wind speed and direction measurement in km/h, m/sec knots and in degrees in the Beaufort scale,
• wind direction introduced graphically using a wind rose,
• rainfall measurement in liters to the square meters and millimeters,
• total rainfall display for the last 24 hours and for the last hour,
• showing maximum and minimum temperature, humidity and atmospheric pressure measurement values along with an hour and a date of registry,
• possibility of setting alarms: high and low internal/external temperature, high and low internal/external humidity, high and low internal/external pressure, high and low internal/external rainfall in a set period of time and wind speed,
• sign of battery depleting,
• possibility of hanging on a wall or setting on a flat surface,
• maximum reading transmission range from the external sensors – up to 25 meters.

Scope of measurements:

• inside temperature: from - 9.9 °C to + 59.9 °C,
• outside temperature: from - 29.9 °C to + 69.9 °C,
• humidity: from the 20% to the 95%,
• atmospheric pressure: 300 hPa - 1099 hPa,
• wind forces: from 0.0 to 180.0 km/h,
• amount of rainfall: from 0.0 to 2499.0 mm.

Power supply:

• station reading panel: 3 batteries: AA, IEC LR6, 1.5V or 230V/50Hz AC feeder,
• outside sensors: 2 batteries: AA, IEC LR3, 1.5V or a station panel cable.

Elements creating a set:

• outside sensor of wind speed and direction,
• outside sensor of temperature and humidity,
• outside sensor of rainfall,
• station reading panel with an internal temperature and humidity sensor,
• panel AC adapter,
• connection cables (including the cable for attaching a station panel to a PC computer),
• service manual.

The wind and rainfall sensors are attached using cables to an outside hytherograph from which using a cable or a radio connection 433 MHz the measurements are transmitted to an internal reading panel and further on to a PC computer.

The meteorological stations are each equipped with a differential barometer which allows on preparing weather forecasts basing on the knowledge of barometric pressure change speed what can have a big practical meaning (in i.e. sports, tourism). Depending on the type of device a value received based on the pressure differences is displayed numerically in hPa/h (hectopascals per hour) or in a form of an arrow showing the direction of pressure changes. For example: value -2.5 hPa/h informing about abrupt worsening of the weather where +0,3 hPa/h allows on expected gradual improvement in weather conditions. Weather forecast is based on it using such symbols as: sun, clouds, rain. The forecast is good for the next 12...24 hours for the area in range of about 30...50 km.

A differential barometer is a dynamic weather forecast. Verification of this weather (based only on the observation of pressure changes) amounts to approximately 70...75%.
