measuring the intensity of the sun's radiation It is one of the most reliable of pyrheliometers and, if carefully handled, retains the calibration value over periods of years One of the principal uses the Angstrom pyrheliometer is as a primary working standard for the calibration of secondary pyrheliometers and pyranometers This new Eppley model is a special development introduced in collaboration with Dr Anders Angstrom The principal improvements over the earlier European models are as follows: (a) Tube length is increased to a maximum commensurate with obtaining the smallest practical aperture angles (effective aperture 5.0°) and minimizing the effect of air currents within the system; (b) Element is of permanent soldered construction and leads to readout instrumentation are continuous; (c) Conical shield behind the manganin strip receivers minimizes reflection and emission effects; (d) Strips and shield are coated with Parsons' optical black lacquer; o PYRHELIOMETER (e) Built-in, heavy-duty microswitch facilitates instrument operation If employed with the associated Eppley control unit, repeatability of ±0.1 per cent, w i t h s t e a d y s k y c o n d i t i o n s , is readily obtained in the pyrheliometer indications This control unit comprises a 4-range precision milliammeter with a fixed 4-point current checking potentiometer (accuracy about 0.01 per cent), an electronic null detector and associated circuitry to permit near simultaneous operation of two pyrheliometers These instruments are calibrated by comparison directly against the Eppley group of primary pyrheliometric standards The latter are periodically compared, on an international basis, to ensure the most accurate reproduction and maintenance of the International Pyrheliometric Scale Individual pyrheliometer calibration (absolute accuracy is better than ±0.5 per cent.)
