Virtual Electronics Company 

The standard Virtual make Weather Station offers professional weather monitoring and outstanding value for money. Our weather stations are known for their precision measurements, rugged construction, wide operating temperature range and low power consumption. The standard weather station consists of a weatherproof enclosure which contains the data logger and power supply, and comes complete with a solar panel, tripod stand and basic range of sensors (Air Temperature, Relative Humidity, Wind Speed, Wind Direction and Rainfall). The data shuttle is a pocket-sized device that can be used to download and transport the data to a personal computer, allowing the Weather station to stay in place for continuous monitoring / recording. The shuttle connects to a PC and is used with the turn-key software to readout and view the data. User friendly Windows based weather station software allows you to view collected data. Data file is saved in Microsoft’s Excel format.

Measure every major environmental condition with this powerful hand-held instrument – barometric pressure, altitude, density altitude, temperature, humidity, wind speed, wind chill, dew point, wet bulb, and heat index. Using its chart mode, itcan recall and graph up to 250 measurements, along with storage times and dates. Measurements are stored manually at the touch of a button. Measurements can also be automatically stored when the unit is turned off. You can even customize screens so that only selected measurements are displayed. Wind speed can be displayed in knots, meters per second, kilometers per hour, miles per hour, feet per minute, or Beaufort force. Temperature, wind chill, dew point, and heat index are shown in either °C or °F. Relative humidity is displayed as a percentage, and barometric pressure can be viewed in hectoPascal (mb) or inches mercury. Altitude and density altitude are displayed in meters or feet. A durable hard cover protects the impeller while allowing other functions to be used. This versatile, waterproof instrument floats, features an easy-to-read backlit display, and has an auto shutdown feature, which activates after 15 minutes without a button press (feature can be disabled). Neck and wrist lanyards, protective pouch, and 2 AAA batteries included.

Digital Rain Gauge:

The 8" diameter collector meets specifications for statistical accuracy. Each time the bucket tips, a count is transmitted to the indoor display, and the gauge empties. You never have to empty the gauge. The counter display up to 249 mm of rain with the resolution of 0.25 / 0.2 mm and can be reset to zero after each rainfall.  A long-life lithium battery with an approximate life of one year is included. Mount this gauge out in your yard and record rainfall inside the Room. This instrument is also available with IMD Pune, certification (At Extra Cost).

Digital Evaporation recorder used for monitoring of water evaporation comes with a weather proof enclosure which contains the data logger power supply, Sensors and comes complete with a solar panel & Pan .The system is powered by two rechargeable sealed maintenance free batteries with integral solar panel, which will easily keep the batteries charged throughout the year. The Evaporation sensor can be attached with this data logger for the collection of real time data automatically. The micro controller has its internal memory along with an additional 128K EEprom, a real time clock with an LCD (16 X 2) to display the instrument status. Data file is saved in Microsoft’s Excel.

Evaporimeter, instrument that measures the rate of evaporation of water into the atmosphere, sometimes called an atmometer. Evaporation rates are so sensitive to the water supply, and the nature of the evaporating surface, data collected by Evaporimeter often do not reflect true evaporation processes; hence, Evaporimeter have limited use. This Pan Evaporimeter is manufactured as per IS:5973 :1970.

Since snow contributes a major amount to the available water, area Values of snow cover are required for estimation of the water resources. It has been established that a combination of remote sensing and ground measurements should be used for snow cover mapping. The Important parameters for hydrological purposes are snow depth, density and snow water equivalent. The reported snow gauge comprises a weighing platform with strain gauge based load cell, a data logger, supporting electronics and a solar panel (SPV) backed battery pack. With this arrangement, precipitation is calculated from the weight measurements of the accumulated water, i.e. every increase in the weight corresponds to a certain volume of precipitation.

There are several types of snow gauges, the simplest of which is simply a measuring stick secured inside a metal container and anchored to the ground. This works well for the measurement of Snow Water Equivalent.  Meteorologists and hydrologists are more likely to use  container attached to a funnel shaped gauge. When the basin is full or the snowfall has ended. The snowfall is then arrived at by multiplying the water equivalent times 10

A Pyranometer is an instrument for measuring solar radiation received from a whole hemisphere. It is suitable for measuring shortwave radiation. This instrument is used extensively in meteorological studies, passive solar system analysis, irrigation scheduling, hydrologic studies and many other environmental studies.  Sensor: Calibration: 0.25 mV per W m-2, Range: 0 to 2000 W m-2, Wave Length Range: 300 to 1100 nm, Stability: 1 to 2% change over a 1 year period, Operating Temperature: - 40 to 55°C, Sensor Housing: Weatherproof anodized aluminum case with acrylic diffuser and  stainless steel hardware. An ideal Pyranometer measures the entire solar spectrum, 280 to 2800 nm. However, about 90% of sunlight energy is between 300 to 1100 nm. Albedo measurement: Provided as per requirement

A Pyranometer is an instrument for measuring solar radiation received from a whole hemisphere. It is suitable for measuring global sun plus sky radiation. The Pyranometer Sensor measures global solar radiation (sun plus sky) for a spectral response graph.

This is a Micro controller based Automatic Wind Monitor reflect state of the art in micro controller based instrumentation design.  Both wind speed and direction sensors can be attached with this data logger for the collection of real time data automatically. The micro controller converts the analog signals from these sensors to digital format. The micro controller has their individual operating software’s programmed in their internal EEPROMS and the data acquired by them is stored in their internal data RAMS. This micro controller remains in the sleep mode and wake up only when either a signal from the sensors is available or when they receive control signals from the master controller for acquiring the stored data. The micro controller has its internal memory along with an additional 512K EEPROM, a real time clock with an LCD (16 X 2) to display the instrument status.

This instrument comes with dual digital display measures speeds from 5 mph to over 125 mph. The unique tilting head folds flat for storage. Water-resistant display can be used in heavy rain. Multi-function display, in mph or km/h. Displays Current Speed plus Average or Max speed at the same time. Comfortable Vinyl handle. 3-cup rotor does not care which way the unit is pointed (unlike those little ones that must be pointed into the wind!). 4% accuracy from 10 to over 50 mph, good to over 100, (plus or minus a few tenths from 4 to 10 mph), Low mass rotor is responsive to gusts.

Wind direction will be measure with a wind vane (see diagram). Wind direction is the compass point from which the wind is coming eg south, southwest, west etc. The unit of measurement for wind direction is therefore compass direction. User plot the wind direction for each day of the month on a special graph called a wind rose i.e. Wind Vane is manufactured as per IS:5799:1970 which indicates the direction of wind at the point of observation.

These screens are manufactured as per IS:5948:1970 and are suitable for housing thermograph, hydrograph, dry and wet bulb, Thermometer and Maximum-Minimum Thermometer.
