Calibration
body temperature measurement system calibration source
thermometers/pyrometers and thermal imagers, designed to provide accurate, traceable and portable calibration on-site. The need for fast, accurate determination of
A
human body temperature has led to the development of a high accuracy blackbody source for 38°C calibration of infrared thermometers/ pyrometers and thermal imagers. The blackbody source is supplied with UKAS
certified (ISO17025) for an effective wavelength of 8 to 14um over temperature 36°C to 40°C which enables optimal online calibration checks of on-site infrared thermometers/pyrometers and thermal imaging systems that measure human body temperatures (typically the face at a distance), to provide highly accurate temperature measurement results. This source is simple and easy to set
up and operate, and can assist in the calibration of infrared thermometers/ pyrometers and thermal imagers used to monitor and detect significant rises in skin surface temperature, which is typically associated with a person running a high fever.

Sound calibratorS with eaSy handling and preciSe calibrationS
G
efell has introduced two high- end sound calibrators - the 4010 and 4011.
The 4010 sound calibraTor
The 4010 is a sound calibrator conforming to IEC 60942 class 1 and ANSI S1.40 for the calibration and the verification of microphones and sound level meters. The combination of two sound
pressure levels and two frequencies allow both level linearity and frequency linearity to be verified. Each sound calibrator is supplied with an
individual calibration certificate. The reference microphone and control circuit together maintain a constant sound
46
pressure level inside the calibration coupler and automatically adjust for changes in load volume, temperature, atmospheric pressure and relative humidity. In addition the sound calibrator
measures the environmental conditions temperature, atmospheric pressure and relative humidity.
The 4011 sound calibraTor
The 4011 generates a sound pressure level of 114 dB at a frequency of 1,000Hz for the verification of the calibration of sound level meters. The sound calibrator can be used for
1/2“ and 1/4“ microphones.
