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. The measurement of water evaporation is important in agricultural, hydro-meteorological studies, in the design and operation of reservoirs, and in irrigation and drainage systems. The rate of evaporation is defined as the amount of water lost by evaporation from a unit area of surface in unit time. For a given area this is

proportional to the depth of liquid water lost in a day from the whole area and evaporation is usually expressed in this way.

The ‘Virtual’ make Non recoding Rain Gauges are manufactured as per IS:5225:1969. Rain Gauge is manufactured from non corrosive fiber glass reinforced plastic container. It consists of collector assembled with brass Ring. Funnel, Locking Rings and Base. The Rain Gauge is supplied with 4 liter bottle and a Plastic measuring cylinder. Rain Gauges are available in 200cm² collection area. The essential parts of an ordinary rain gauge are a funnel through which the rain water is collected in a receiver and a measuring cylinder (rain measure) with which the rain water collected is measured. The correct type of rain measure suitable to the type of rain gauge in use has to be used for the measurement of rainfall. The rain measure is graduated for every 0.2 mm of rainfall.

The ‘Virtual’ make Self recoding Rain Gauges are manufactured as per IS:5225 :1969. Rain Gauge is manufactured from non corrosive fiber glass reinforced container. Recording rain gauges are used to obtain a continuous record of daily or weekly rainfall. It consists of a funnel-shaped collector at the top of the gauge and a float syphon chamber and recording mechanism just below it. the rain water collected by the collector is led into the float chamber. The float is having a central stud on which a pen assembly is fixed. The pen is moving over a daily chart wound over a clock drum. After every 10 mm of rainfall syphoning occurs and recording of rain starts afresh. Supplied with Quartz Clock and Charts for One year.

This data logger (Model: Rainlog) connects to most standard tipping bucket rain gauges and records rainfall rates, times, and duration as

well as momentary contact events and temperature. Because event data is stored when it happens, memory is efficiently used. Data can be viewed in inches or millimeters. Tips are logged with time-stamps to gauge rainfall intensity, and the lockout feature eliminates false

readings from tipping-bucket bounce. One year capacity – both logger and battery supply. One minute time/date stamp resolution. Flash

memory. USB connectivity. Windows® software included.

The ‘Virtual’ make Wind Vane is used for determining instantaneous wind Direction. Surface wind is best measured by a wind vane and anemometer. Wind direction is defined as the direction from which the wind blows and is measured clockwise from geographical north. Wind direction compass points from which direction the wind is coming e.g. 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. Wind Vane is manufactured as per IS: 5799-1970 which indicates the direction of wind at the point of observation.
