GOWH0003 - Anemometer
Classic design demonstrates the operating principle of cup anemometers; cup rotation reflects changes in air velocity. Since this extra sensitive model responds to wind velocities as low as 2 mph, a standard electric fan may be
used as the wind source.

GOWH0047 - Glass Barometer, Goethe Barometer
Indicates changes in air pressure quickly and accurately. The ball is filled with colored distilled water. Once filled the air trapped inside the ball is no longer subject to variations in atmospheric pressure. The liquid in the indicator tube, however, remains open to the atmosphere and is directly affected by atmospheric pressure. When atmospheric pressure rises, the liquid in the indicator tube is pushed down and an improvement in the weather can be anticipated. When air pressure falls, the greater pressure inside the ball causes the liquid in the indicator tube to rise, indicating that a deterioration in weather (storm) can be expected.
Sizes available for selection (height): 10cm, 13cm, 15cm, 17cm, 20cm, 25cm
Color choices of liquid: red, blue, green
GOWH0058 - Storm Glass, FitzRoy Glass

Height sizes available for selection: 14cm, 15cm, 16cm, 18cm
GOWH0069 - Galileo Thermometer
This fascinating and functional instrument was designed in the 16th century by Galileo Galilei, who discovered that as a liquid's temperature increases, its buoyancy decreases. Each glass sphere is precision crafted, filled, and calibrated within 1/10°F. Accurate within ± 4°F.
Sizes available for selection (height): 15cm, 18cm, 24cm, 28cm, 33cm, 37cm, 40cm, 44cm, 56cm, 60cm

Anemometer Cup Counter
The Cup Counter Anemometer measures the run of wind past the Instrument over a period. The instrument consists of three semi-conical copper cups 127mm in diameter with beaded edges fixed to a central spider by three brass rods. The cups assembly is friction coupled to a vertical spindle, There is a small ball bearing at the top of the spindle and another ball bearing at the bottom. The cup wheel spindle is of stainless steel and connected worm gearing to a revolution counter mounted in a water proof housing. By observing the counter reading at the beginning and end of any period of interest the average wind speed during the interval can be calculated.

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 glass measuring cylinder. Rain Gauges are available in 200 sq. cms collection area.
Self Recording Raingauge
Rain Gauge is manufactured from non corrosive fiber glass reinforced plastic container.
Recording raingauges 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.
Tipping Bucket Raingauge
A tipping bucket rain gauge is used for measurement of rainfall. It measures the rainfall with a least count of 0.5 mm. Rain Gauge consists of Fiberglass body & twin buckets mounted on a horizontal shaft. It has two stable positions. The collector area of the rain gauge is 324 cm2 . Thus a volume of 32.4 cm3 corresponds to 1 mm of rainfall. The rainfall collected by the receiver reaches to one of the twin bucket through a funnel. The weight of rain in bucket causes the tilting of the bucket from position to another position and brings the other bucket under the funnel for collecting water. Every time the bucket tilts the small magnet attached to the horizontal shaft of the bucket actuates a reed switch generating one electric pulse. Facility for leveling the bucket and proper calibration are also provided in the Tipping Bucket Rain Gauge.
The pulses are counted by Digital Datalogger & stored alongwith Date & Time in its internal Memory. The stored data can be downloaded to PC in Datasheet format & analyze it using any spreadsheet software.
Models : 0.5 mm / 0.01 inch per tip

Water Current Meter Magnatic Type
Water Current Meter Magnetic Type : (Fish Type weight) complete in wooden box with accessories. Duly calibrated by Govt. Lab
Cup Type Water Current Meter
Water Current Meter (Cup Type), which are used for determining velocity of flowing water in open channels and streams. Made in compliance our Water Current Meter (Cup Type) is able to cater to any and every water current measurement need of our clients.
Construction and Working :
- Consist of six cup assembly mounted on a vertical shaft
- This shaft is held vertical in a yoke frame on two pivot points.
- Yoke frame while holding the moving assembly protect its cups from damage from the Floating bodies in flowing water, he vertical shaft rests on a pivot point at the lower end, which is adjustable
- The upper end of the shaft is held in at a pivot position inside the magnetic contact Chamber, which is made water tight by a cap.
- The magnetic contact chamber is equipped with Two contact switches the terminals of which are located outside on the body of the contact chamber.
- Only one switch is used at a time, the other is a spare and stands by switch and can be used immediately, if one goes out of order.
- The other end of the contact terminal (earth) is the yoke frame itself and so a common earth terminal has been provided on the yoke frame.
- The bucket wheel rotates in between two pivots in the yoke frame.
- Each revolution of the bucket wheel makes a contact of the magnetic switch in the magnetic chamber which can be recorded on a counter. The yoke frame consists of a tail fin with a balance weight, which moves in a slot and can be adjusted at any place within slot.
- The balancing weight is so adjusted so as to keep the current meter horizontal when suspended in water
- The tail fin keeps the yoke frame with the bucket wheel to the upstream direction as the tail fin goes to downstream direction with the flow of water
- The meter is suspended in water with the help of a suspension flat in deep water, and by a suspension wading rod in shallow water.
Pygmy Type Water Current Meter
Pygmy water Current Meter is used for Stream-flow measurements in shallow streams, flumes and small channels, where the velocity of water does not exceed 1m/sec. The principle of operation is based on the proportionality between the velocity of water and the resulting angular velocity of the meter rotor. By placing a current meter at a point in a stream by Wadding rod and counting the number of revolutions of the rotor during a measured interval of time, the velocity of water at that point is more...
Complete with accessories in box. Duly calibrated by Govt. Lab
