V- TECH 477 LED Stroboscope allows the motions to appear incredibly quick and sluggish. This allows you to control and inspect machines and systems during operation and to measure speeds of up to 300,000 rpm. The naked eye can not say if a knitting machine’s thread guide works correctly. This is also therefore not possible to say that there are anomalies in equipment or structures vibration or rotational processes. But the V- TECH 477 LED stroboscope is another matter. The stroboscope creates a series of flashes that look to you like a ‘frozen picture. The LED V-TECH 477 will even calculate the spinning speed of very small objects. And as reflex marks are not required, the devices must not stop and production processes must not be interrupted either.

Description:

Holiday Detector is an instrument used to detect holes in anti-corrosive coating (electrically insulated) on metallic pipes/ surfaces. This test is carried before the pipes are laid underground. The pipe is connected to earth (nominal) and an electrode, charged to high tension, is moved over the coating. At the place of a hole, arcing takes placce and the instrument gives alarm. The Instrument consists of an electronic oscillator to convert small DC voltage (12V) to AC. A high voltage rectifier to give high tension DC output. Holiday Detector is a fully solid state device and has no moving part except the indicator pointer (Digital readout on special demand can be supplied). This has made the device maintanance- free. Portable and light- weight. 

The Preamature corrosion of a substrate is often due to failure of its coating. It is therefore essential to test the non conductive coating for pin holes. Wet sponge technique is most suitable to do the job. The Instrument generates 90 V DC. Negative end of this supply is connected to substrate. Positive is connected to the moistened sponge brush. When the sponge is moved over a pin hole, solution penetrates the flow and feeble electric current flows to the substrates and completes the electrical circuit. This generates Audible and Visual Alarm. Test voltage 90 volts is generated using Inverter circuit. The circuit operates on rechargeable stock of cells.

A Reflectance Meter is a precise instrument used to measure the reflectivity of surfaces by quantifying the amount of light or radiation that is reflected off a material. This device is essential in a variety of industries, such as coatings, paints, textiles, and environmental monitoring, to assess the quality, texture, and appearance of materials based on how much light they reflect.

Key Features:

• Accurate Measurement: Provides precise measurements of reflectance, typically expressed as a percentage of light reflected from the surface.
• Wide Range of Applications: Suitable for a variety of surfaces, including matte, glossy, and textured materials, in industries such as manufacturing, automotive, textiles, and architecture.
• Digital Display: Equipped with a clear, easy-to-read digital display that shows reflectance values in real-time, ensuring quick interpretation of results.
• Portable and Lightweight: Designed for easy handling, making it suitable for both laboratory and field use, especially for on-site testing.
• Simple Operation: Offers intuitive controls that allow users to quickly measure reflectance with minimal training.

Product DescriptionFree Fatty Acid (FFA) Meter is a microprocessor based portableinstrument measures the acid value of Oil samples. The fay acids in Oil get detached from the triglycerides during manufacturing or improper storage. The Free fay acids contributes to Oil rancidity and causes deterioraon and oavour of the Oil. The lower the FFA, the beer is the oil quality and its preservation status.
In measurement, the sample Oil is treated with reagents to form a colored dye. The instrument measures the absorbance of the colored dye and relates it to the free fay acids as % of Oleic acid. The instrument is previously calibrated using FFA standard Oleic acid of known concentraon. 
Features
• Portable with rechargeable Baery
• Comprehensive procedure for sample preparaon
• Drasc reducon in reagents and sample in comparison to
• Quick Analysis of sample in <5 minutes
• No use of hazardous chemicals
