NPL has combined its expertise in temperature and humidity measurement in order to offer clinical thermometer calibrations.
The ISO standard relating to medical electrical equipment (ISO 80601-2-56) specifies specific temperature and humidity environments in which portable thermometers must be proven to operate.
NPL offers a calibration facility to meet this standard, using the combination of a dry-block calibrator facility placed inside an environmental chamber. A series of fixed temperatures over a range of ambient temperatures (from 15 °C to 45 °C) and humidities (from 20 %rh to 80 %rh) can be accommodated. The time response of the device to applied heating and cooling can also be measured, in accordance with the standard.
