	Calibrators Calibrators or process calibrators are used for basic measuring, testing and regulation techniques for setting and verifying test installations and instrumentation. Calibrators have different magnitudes that should be attributed to normal measurement signals. These measurement signals or regulated magnitudes are denominated as the test signal, which our calibrators can provide. They are defined as 0 to 20mA, 4 to 20mA, 0 to 10V and 0.2 to 1 bar. These magnitudes signify, for example, temperature, output or settings of a test valve (0 to 100% of valve opening). This signifies that for a regulating signal of 50% (eg. 10mA) with an input range of 0 to 20mA in a test valve, the valve opening will be 50%. As these correlations are very important for a good functioning test and the transmission of process signals, all measurement instruments and regulations should have been previously calibrated with our calibrators. Instruments that are already functioning should be verified regularly and, if necessary, recalibrated wth process calibrators, ensuring the level of quality desired. Easy to handle devices or instrumentation, such as infrared thermometers or sound meters, can be and should be verified regularly wth temperature or sound calibrators when a variation is suspected which is greater than that stated in the technical specifications of the device. Our high quality calibrators offers these possibilities to experts, in measurement techniques, testing and regulation or in quality control with an excellent relationship between price and quality, which is not typical of this range of devices. If you don't find the calibrators you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 ( 0 ) 191 377 3398 and our technical staff will advise you regarding our measuring instruments. Technical specifications for calibrators can be found at the following links:
	- PCE-123 series calibrators (indicates nominal value for simulations and measures electrical signals and frequency)
	- PCE-C 456 series calibrators (calibrators for simulations and graphic measurement / pulse generator (easy and cycle ramps)
	- PCE-IC1 series calibrators (calibrators for infrared temperature to accurately test infrared devices up to 350°C)
	- PCE-SC41 series calibrators (Class II sound calibrators for verifying the precision of sound meters)

Calibrators are also denominated as calibration systems and are used for setting, measuring and calibrating voltage, pulses, current, resistance and frequency signals. Not all calibrators have this capability. Depending on the requirements, there can be the need for different devices or models. In case there is the need for some or all of the properties previously mentioned, a multi.function device should be considered. Multi-function calibrators allow for the normal measurement of varous values, generally allowing them to be read simultaneously. High quality devices are ideal measurement of voltage, pulses, current, resistance and frequency signals, such as in simulation and measurement of resistance thermometers and thermal elements. This last point, about measurement and simulation, is also described in the devices as the abreviation "TC". Resistance thermometers are abreviated to RTD. As well as multi-function calibrators, calibrators are available for pressure, sound, processes and blocks. These are the most common types of calibrators.
