As an example , consider: A camera precision is + – 2 C to 100 C or + / – 2% of reading. With this value held, say, 250 degrees C, the instrument can now read 245 255 degrees C (+ – 5 degrees C). When it comes to the radiant temperature, this type of accuracy (ie 0.5%) difficult to obtain. The reason is that the emissivity (E) Reflectivity (R) and transmission (T) tend to induce errors equal to or greater than 2% of value shown. For this reason, the primary rules of radiant energy is typically carried out in the laboratory. These rules are intended to greatly reduce errors ERT.
R and T in these rules will be negligible and E is 0.995 and at most, in most cases. These rules are laid down in themselves (usually) + – 1-2% or less of reading or full scale. Importantly, these rules often derive their value from the temperature and control cooling and thermometry built because of this, it can be calibrated to greater tolerance, if necessary. Calibration Certification Certification of calibration is intended to quality and provide a legal instrument for a manufacturer, user or customer to ensure the values of a physical reality. In its simplest form, the certificate is a document intended for traceable, for: repeatable accuracy in the statements, the identity of instrumentation, instrumentation holders and performers of the calibration standard for calibration of infrared cameras / imagers If you send your team to calibrate infrared thermographic camera, is likely to black body is used and the range of costs used, from about $ 500.00 new, up to $ 1,500.00 or more, plus the cost of certificates of traceability.
