About Nagman & their Services ........

Nagman was established in the year 1972 and has been serving the Indian industry with distinction since then.

Nagman, starting small, manufacturing RTD / TC sensors, moved on (in the late eighties) to pioneer the concept of portable calibrators (simulators) for Temperature / Pressure under technical guidance from Ametek (Jofra), Denmark and have been manufacturing these calibrators, selling over 5000 calibrators so far.

Nagman, using this technical expertise on portables, developed Comprehensive Calibration Work Stations / Test Benches - for Temperature, Pressure, Electrical parameters - in modular design and over the past decade have installed these benches in many reputed industries.

Nagman were also closely associated with M/s. Eurotron – Italy, S.I. Pressure Instruments – U.K., Revue Thommen – Switzerland, Ametek (Europe) - Germany, Tradinco – The Netherlands to market & service their products in India. Nagman, in co-operation with / support from these & other reputed overseas principals, improved on these simple systems to offer highly sophisticated and dedicated Primary and Secondary Standard Calibration Test Benches, including Computer Aided Calibration Systems - comparable in design, performance, features and accuracies to reputed / established International brands like M/s. Scandura - Italy / Beamex - Finland, but at affordable prices.

In the recent past Nagman have developed and introduced several innovative & novel import substitute products including – Hand held Dry Block Calibrators, Portable (Micro) Oil Baths, Black Body Sources, Fluidized and Hot Cold Baths, Multi-hole Very High Temperature Dry Block Calibrators (1200C/1500C) etc. These Calibrators will be offered with CE / UL / CSA (U.S.A) Certifications. In addition Nagman have also developed & introduced a cost-effective range of Dead Weight Testers (Hydraulic & Pneumatic) (0.1%, 0.05% & 0.025% accuracy) and Comparison Testers / Master Gauges.

Nagman have also developed and introduced several utility Instrumentation Software Packages : including Data Management / Calibration Management (integrates several reputed brands – makes of Calibrators and Digital Multimeters) / Asset – Maintenance Management Software Package etc. and have the capability to accept development of custom design assignments in Instrumentation software.

Nagman have built up a sophisticated "Center for Calibration" to fully support – thro’ Traceable calibrations year after year - above systems and calibrators. The facilities include the unique Cross Float DWT Calibration systems, ultra low pressure calibrators, Black Body Sources (for IR Pyrometer calibration), Universal Calibration System (Wavetek's Model 9100) among other routine pressure, temperature and electrical parameter calibration standards. This Center for Calibration offers Site (including overseas customer site!) as well as Lab Calibration & even offers Calibrators (Transfer Standards) on Rental! This Center for Calibration also offers Training Courses & Seminars on Calibration methods & techniques. This Centre for Calibration enjoys the unique distinction of obtaining NABL (equivalent to UKAS) Accreditation for Thermal / Electro-Technical & Mechanical (Pressure / Mass) parameters to be able to offer Traceable Calibration Certificates.
