  • Non - Contact Voltage Detector

    Model 273 HP - KUSAM-MECO

    The 273 HP is a Non-contact voltage detector. It has two ranges for selection.The 273 HP consists of an internal pickup sensor, a function selection switch, a visual and a sound annunciator. With the 273 HP, physical contact with electrical conductors is not necessary when testing for live lines. Its sensor senses the radiated field which surrounds live conductors. Radiated field strength increases with voltage and decreases quickly with distance or earth shielding

  • Non-Contact Voltage finder

    PeakTech Prüf- und Messtechnik GmbH

    Easy to use, for non-contact detection of AC voltage from 50 V to 1000 V. Suitable for outlets, lamp sockets or against wire insulation testing. Suitable for conductor tracking of flush-mounted cables and localisation of line interruptions. If AC-voltage is at the measuring point, it is visually indicated by a flashing red LED and the integrated buzzer sounds. The probe lights green when the measuring point is free of voltage.

  • Psyacoustic Test System

    Jumho Electric Corporation

    Psychoacoustics is the science of the relationship between physical quantities of sound and subjective hearing impressions. To examine these relationships, physical parameters, such as loudness, sharpness, roughness, fluctuation strength, are mapped to hearing-related parameters. Unlike the physical quantities, these hearing-related quantities – also referred to as psychoacoustic parameters – provide a linear representation of human hearing perception. The psychoacoustic test system, with interactive interface and user-friendly operations, analyzes psychoacoustic parameters effectively and conforms to the international standard ISO 532 Part B.

  • Water Level Indicators

    Integrated Geo Instruments & Services Private Limited

    Water Level Indicators with counter mechanism is a very handy device to quickly check the level of water in open wells and in bore wells. A sensor attached to the end of a cable, wound on a winch is lowered in to the well over a calibrated wheel attached to the counter mechanism. The moment the sensor touches the water surface, a panel meter on the winch which is on the ground shows full deflection with buzzer sound. The depth to the water level from the ground can be read off in metric scale on the counter.
