       Black body calibration sources from Nagman permits the calibration of infrared temperature sensors with low uncertainty. This editorial elaborates on what makes the most excellent black body calibration source for a specified function and what you should judge when selecting one.    A black body calibration source is a tool for examining the calibration of an infrared temperature sensor. It consists of a heated or cooled target object whose temperature is accurately known and is the foundation for accurate calibration of infrared pyrometers.      The black body calibrators are a perfect radiator i.e. it emits thermal energy whose power at a given wavelength and temperature follows Planck’s Law of radiation. It absorbs and emits all radiation and has an emissivity rate of 1.    Since there no matter exists that could make a true perfect black body, in practice, a black body calibration source for all time has a slight...

  Nagman offers a series of transportable Dry Block Calibrators for temperature calibrations. A steady temperature profile is formed using the inhibited heating device, fitted with the sensors/probes that require calibration. Our range of Dry Block Calibrators comprises of the main cabinet with easy access to all controls, connection options, power inlet, etc. The Dry Blocks are outfitted with a solid handle for suitable and secure handling – a protective carrying case for carrying is also an option. The numerous diverse inserts were intended to go deep into the temperature calibrator in order to guarantee stable readings for a variety of sensors and probes. The high steadiness throughout the complete calibration zone is achieved by means of a superior and instinctive menu-driven controller with active dual-zone heating technology, in which every heating zone is separately controlled to recompense for possible heat loss. Temperature Calibrators   Temperature is the m...

  Measuring pressure cannot prove to be an accurate job. No matter how many times the readings are taken, mistakes are bound to happen. In order to avoid mistakes and provide accuracy in measurement in Nagman’s Comparison Testers . Comparators at Nagman Instruments and Electronics Private Limited are manufactured with the best of care and a watchful gaze so that the devices will not create any issues for the user. These Comparison testers are divided into Hydraulic and Pneumatic out of which Hydraulic Comparators are used to measure medium and high pressure whereas Pneumatic settles to measure low pressure. The comparators by Nagman are best suited for companies who work on a budget as it requires very low maintenance cost and is extremely compact. The device can be carried without feeling heaviness or difficulty to labs and fields. They also come with a adjustable foot. The hydraulic and pneumatic comparison testers differ in terms of pressure medium where Hydraulic pref...
