Vaiseshika Multivalue Calibrator, Type: 9409 CAL is an accurate and reliable calibration instrument suitable for calibration of Kelvin Bridges, Ductor Testers and MicroOhmmeter. It employees various of high current standard resistors that ensure precision and reliable calibrations.

The instrument consists to two potential terminals and two current terminals.High quality Gold / Silver plated terminals are used to achieve very low contact resistance and thermal EMF. The instrument employees high stability manganin resistance wire and strips to provide precision calibration &

stability to the instrument.The whole instrument is housed in a portable cabinet for safe working and

onsite calibrations.

"Vaiseshika" High Precision Decade Resistance Box Type7400 has been designed and fabricated to meet the standard calibration requirements. This Decade Resistance Box can serve the purpose of Precision Resistance Simulation and substitution in electrical circuits, Sensors calibrations in Test & Calibration Laboratories.

Vaiseshika has designed a Fixed Value Insulation Tester Calibration System which can be suitably used for the purpose of calibration & testing of Insulation testers and megohm meters with impressed test voltages upto 5000 volt. This instrument provides single point fixed high resistance values anywhere between 100 kohm to 10 Tera ohm. The fixed point values can be selected by the customer. Custom built instrument can also be designed and manufactured, by Vaiseshika, for the calibration laboratory. The instrument is constructed in metallic / rugged high strength polymer case, for field calibration.

"Vaiseshika" Decade Megohm Box has been designed and fabricated for the First Time in India to provide Calibration Standard for High Resistance Substitution. This instrument employs silver alloy silver plated and silver alloy gold plated switches mounted on high insulation ceramic wafers / phenolic material.

Vaiseshika High Voltage Probe is designed to measure the voltage of an AC/DC voltmeter from 100 volts to 15000 Volts (15 kV). As per the Principle of High Voltage Probe, Input of Probe is connected to the High Voltages Sources (Range 1000Volts), where Multimeters cannot measure the voltage beyond 1000 Volts & output is connected to the Voltmeter.

description:

• vaiseshika thumb wheel resistance box, type: 7400a is a resistance standard substitution instrument.it can be used as a source of resistance of a known accuracy of the order of 1%. It is used for selected test applications in r&d or pt100 simulation, in the process industries.

applications: for the calibration of;

rtd/ temperature sensors, simulation and calibration.

load cell and strain gauge calibration.

"Vaiseshika" DC STANDARD RESISTOR 9409 has been designed and fabricated to meet the standard calibration requirements. These Standard Resistors can be used for calibration.

To ensure stringent accuracy, high degree of stability and utmost reliability, the Manganin wire and strips have been used to construct Standard resistors. These Standards incorporates the manganin coils which have been subjected to prolonged ageing and heat treatment, to improve stability and to reduce temperature coefficient. Joints are silver soldered with copper being used for connection to terminals. Resistance elements are sealed in aluminium container having moisture free oil. Use of oil improves cooling effect which in turn imparts greater stability to resistance.
