Profile: Absolute Calibration Ltd. is a calibration service provider. We are accredited to BS EN ISO 9001:2008 quality standard. Our calibration service spectrum encompasses areas like DC voltage & current, resistance, capacitance, inductance, temperature, humidity, pressure, microwave, and RF applications. Our resistance calibration and measurement capability is for 4-terminal resistors suitable for oil immersion process. We also calibrate passive and active devices up to 18 GHz. We demonstrate temperature calibration services with a variety of fluid baths, a fluidized alumina bath, and a high temperature furnace, all of which provide very stable isothermal environments for the temperature calibration of platinum resistance thermometers, and thermocouples using comparative techniques.
