1010.5 EARTH/SOIL THERMOMETERS : For measuring earth’s temperature at depths from surface down to 1m. It has the advantage that Readings can be taken without disturbing the thermometer. Thermometer is mercury in glass with its stem bent at 30 Deg just below the scale. The lower portion is placed vertically in the earth with bulb at the required depth.
Range : 10 to 55 Deg C
Depths available 5cm, 10cm, 20cm, 30cm, 50cm and 1m

1010.6 STAND FOR THE ABOVE : A metal stand made of thick gauge MS strip fixed with two clamps to hold the thermometer in position. Lower part can be inserted into the soil.

1010.7 THERMOMETER SCREEN :For use with four meteorological thermometers for their protection against Radiation and precipitation. The screen is a rectangular box made from seasoned wood. With all its 4 sides double louvred and provided with hinged front door. The roof is double and the bottom consists of overlapping boards separated by an air space. All 4 thermometers can be fixed inside the screen on the frame work provided inside it. Painted white with chlorinated rubber base paint.

1010.8 RAIN GAUGE : This is Symon type ordinary rain gauge. The outer body is made entirely of light, rigid and robust Fiber glass reinforced polyester. The collector is fitted with non-rusting gunmetal rim. Complete with rain collecting bottle and rain measuring cylinder.
Cap (a) 100 cm sq. collecting area. (b) 200 cm sq. collecting area

1010.9 SUNSHINE RECORDER : Campbell-stokes pattern, for the self recording of duration of Sunshine from Sunrise to Sunset of the day. This is a tropical pattern suitable for use in the latitudes 5 Deg South to 45 Deg North. Bowl made of Tin Bronze surface finished black painted and hard Lacquer, with cut glass sphere mounted concentrically in a section of the spherical bowl, the diameter of which is such that when the instrument is exposed to sun rays they are sharply focused on a card held in the grooves of the bowl, the focused Sun ray’s burn a trace on the recording card which has a time scale printed on it. The length of the burn indicates the period of bright Sunshine during the day. Complete in a wooden box with the recording cards for one year.

1010.10 SEISMOGRAPH MODEL : Earthquake shock waves are recorded in the same manner as demonstrated by this model, by mounting the model to a table and vibrating it, earthquakes can be simulated and recorded. The recording pen is attached to a weight suspended from a support which moves with the vibrations while the recorder remains stationary because of its inertia.

1010.11 WIND VANE :A heavy duty wind vane comprising a balanced vane rotating through a double ball bearing axle made of S.S. All the directional arms can be detached, fitted on a heavy cast Al. Base with 1 1/2" Galvanized pipe. Epoxy painted to sustain weather hazards.

1010.12 ANEMOMETER CUP COUNTER TYPE : A 3 Cup wind Anemometer coupled with a mechanical counter housed in a cast Al. box giving the total wind run. Cups made of hard plastic.

1010.13 ANEMOMETER VANE TYPE : A vane type wind Anemometer coupled with an analogue scale giving the total wind run.

1010.14 ELECTRICAL WIND VELOCITY/DIRECTIONAL INDICATOR : Remote mounting type. A complete instrument with remote mounting facility to show the wind velocity and wind direction on a display unit which can be kept in a separate hut 30m remote cable. With or without mounting structure.

1010.15 WEATHER STATION, SIMPLE FORM : Comprising a self assembly weather screen with one wind vane and one Anemometer, a wet and dry bulb hydrometer, a maximum and minimum thermometer, housed in a thermometer screen made of seasoned wood with louvers at all 4 sides, front openable hinged with chain, painted white.
