Faultlessly designed and manufactured, our Extensometers are of utmost quality. We are entrusted with a task of manufacturing, exporting and supplying Extensometers in the global market. The Extensometers that we bring forth can be used with specimen of thickness of thickness 3mm to 25 mm and have variable gauge lengths. Buyers can acquire them in tailored specifications, from us.

Specification : It is Demountable Type Extensometer used for measuring strains in Structural Components. it can be used with specimens of Thickness or Diameter 3mm To 25 mm. Gauge Length is also Variable in Steps on 10 mm From 30 mm to 120 mm. it used two Dial Gauge to Measure Strains. Both the Gauge are read simultaneously and there average is taken as the Strain of the Sample Under Test. Gauge Length Bars are three pairs in number the first one is for 30 mm to 60 mm, Second one is for 30 mm To 100 mm, and third is for 30 mm to 120 mm. the lower Knife Edge Point is Spring Loaded while a clamp has been provided for the upper knife edge contacts and can be used if and when required.

Details :

• With two Dial Gauge least count .01mm x 5 mm Range (Mitutotyo Make)
• With two Dial Gauge least count .002mm x 2 mm Range (Backer Make)

Note : Other sizes and gauge length are available on request.

The technologically advanced Water Current Meter (Propeller Type) offered by us is ideal for the measurement of velocity of flow of water in open channels and streams. Fabricated in compliance with IS 3910, our Water Current Meter (Propeller Type) has been termed as the best available in the market. Construction and Working : Consist of six cup assembly mounted on a vertical shaftThis 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 waterThe vertical shaft rests on a pivot point at the lower end, which is adjustableThe 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 counterThe 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 waterThe 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 waterThe meter is suspended in water with the help of a suspension flat in deep water, and by a suspension wading rod in shallow water.

We are proud to offer high tech Siltometer as part of our product range. The technologically advanced Siltometer offered by us is widely used for measuring settling rate of particles in column of liquid (usually water). Our Siltometer uses incremental method, to measure this settling rate and determines the rate of chain of concentration of the suspension at a known vertical distance below the upper surface of the suspension. The optimum performance, easy operations and accurate measurement, makes our Siltometer the best available digital meter available in the market. Variants :

• Optical Lever Siltometer :
• Method used : Incremental method
• Use : determines Indirectly the rate of chain of concentration of the suspension at a known vertical distance below the upper surface of the suspension
• Puri`s Siltometer :
• Method Used : Cumulative method
• Use : To measure the rate of accumulation of the material by measuring the deposited sediment at the bottom of the tube
