Test Instrumentation

A concrete moisture meter is a device used to assess moisture levels in concrete slabs, crucial for preventing damage before applying flooring or coatings. These meters operate using either pin-type or non-destructive pinless technology and provide a relative indication of moisture content in the top layer of the concrete

Soil Tensiometer 75cm for Soil Moisture & Water Tension Measurement in Agriculture

We specialize in supplying a comprehensive collection of soil tensiometer. this device is widely used in the agriculture industry for testing moisture content in the soil for its maintenance. we fabricate this product using optimum quality raw components procured from reliable sources.

FEATURES:

· The Tensiometer can test soil maintenance moisture content

· Tensiometer measures the force with which water is held in the soil by the soil particle

· This force, referred to as soil suction, tension, or potential, indicates how tightly the water is bound in the soil, and how much energy must be exerted by plant roots to remove and use the water

· The basic components of a potentiometer include a porous ceramic cup, a plastic body tube, and a vacuum gauge

· The ceramic cup is placed in good hydraulic contact with the soil and allows transfer of water into and out of the Tensiometer body according to the tension in the soil

 

· The vacuum inside the Tensiometer body equilibrates with the soil water tension, and the dial gauge provides a direct readout of the tension

Caltech Engineering Services offers Barcol Hardness Tester. Barcol Impresser Hardness Tester is used for testing the hardness of aluminum, aluminum alloys, fiber reinforced plastics (FRP), copper, brass and other rigid materials including plastics, fiberglass & FRP having hardness. Barcol Impresser is a portable, handheld, indentation hardness tester can be operated with no prior experience. Simply apply pressure against the instrument to drive the spring-loaded indenter point into the material. Indenter point must be perpendicular to the surface being tested. On very soft materials, the highest reading should be used since cold flow permits the spring loaded indenter point to continue penetration.

Barcol Impresser Hardness Tester can be used in any position and in any space that will allow clear reach for operator's hand. Hardness reading is instantly indicated on the dial, which is divided into one hundred graduations. No waiting, pre-loading or separate measurements.

Propeller Type Water Current Meter is used to measure velocity of water flow directly in m/s. The stainless steel spindle carrying the cup wheel freely rotates in the bearing assembly. The magnet and reed switch assembly produces one pulse per rotation. The rotation of the Water Current Meter is sensed by sensor & gives pulsed output signal.

As per IS: 3910-1966, the Water Current Meter employs a bucket wheel assembly that is mounted upon a shaft and rotates in response to fluid flow, generating a signal that is proportional to the fluid flow velocity. The current bucket wheel assembly is made of plated brass. It employs six hollow conicalcups that are hand formed from sheet metal and individually soldered to a brass, star-shaped frame. The finished unit is then plated. The frame is shaped so that a strut connects the apex of each cup to the outer diameter of the following cup around the frame.

The Propeller Type Water Current Meter can be suspended by means of a Fish Weight while wading a stream, or by a cable and wading rod from an overhead structure. A tail pieceassembly assures proper alignment of the meter to water flow when suspended by a cable. Velocity is determined by counting the number of revolutions of the bucket wheel over a given period of time.Revolutions can be monitored by several means. "LYNX" make Digital Water Velocity Indicator / Logger (sold extra) by configuring the indicator with calibration equation (provided with each meter), it will result the direct current velocity of the stream in Meter per second.

The meter is made from brass and stain less steel and all exposed surfaces are chrome plated forcorrosion-free service. Each Current Meter is provided with a standard rating table to convert bucket revolutions to stream velocity in Metric units (meters per second), spare parts, instrument oil, cleaning cloth, screw driver and a rugged carrying case.
