Description

Decade Resistance Box consists of decade switches with resistors. Each decade switch has 1-10 positions in addition to zero position. Specially designed switch with self cleaning and silver plated contacts ensure very low contact resistance and long life.

Resistances of 10 k ohms & lower are made of non-inductively wound selected manganin. Coils are heat treated and aged for long term stability.

100k and 1M ohm decades have selected & precision metal film resistors of very low temperature co-efficient. All the decades are housed in metallic/wooden rugged casing and are provided with knobs having ribs for comfortable operation. Decade Resistance Boxes are available with 4, 6, 7 & 8 decades and offer a wide choice of resistances to meet with almost every requirement in industry & laboratories.

Toshniwal Industries Pvt Ltd. (TIPL), an ISO 9001:2008 certified company is a Private Limited company incorporated in 1959 at Mumbai. The company was set-up under the aegis of Toshniwal Brothers Pvt. Ltd. (Estb. 1948) under the guidance of its founding Chairman & Managing Director, (Late) Dr. G.R. Toshniwal, D. Sc. And thereafter his son Mr M.G. Toshniwal, B. Sc (Engg.). In a short span of time, TIPL was recognised as a leading instrumentation company in India as a manufacturer of quality instruments and excellent services to customers.
Manufacturing commenced in a spacious factory setup at Ajmer in 1963 in technical collaboration with world leading instrumentation companies like Hartmann & Braun, Germany; British Electric Co. Ltd., UK; W.G. Pye & Co., UK. After completion of the term of these collaboration agreements, TIPL continues to manufacture instruments as per the technical know-how received. Many of the instruments, as per the collaborator’s designs, have been up-dated with the efforts of their in-house R&D. Since 1984, TIPL has taken up the marketing of various related product lines from renowned manufacturers from Japan, USA, UK & Germany and provide complete application engineering, installation & commissioning and after sales service support to customers.
Mrs. Manju Toshniwal, Chairman and Mr. Rajeev Toshniwal, Managing Director of TIPL have a long experience of managing medium size engineering industry and are supported by a team of professionals. TIPL owes its technological leadership to its engineers and business managers backed by a dedicated work force.
