System-Photometers S 1000
The digital system photometer S 1000 is an universal precision instrument for the measurement of illuminance E with a 4-digit display and a standard measuring range from 10-4 lx (last digit) to 5 × 105 lx in combination with a system photometer head type SP 30 S0T, 30 mm diameter, V(λ)-corrected Si-photoelement (version B). The sensitivity can be increased to 10-5 lx (last digit) in version C.
As an option, the calibration setting can be switched from lux to footcandle, candela, lumen, or ampere.

The system photometer consists of a system photometer head with built-in photocurrent amplifier and a measuring console within a 19-inch housing which is line-powered. For both the system photometer head and the measuring console, several options are available.
The S 1000 is a high-precision measuring equipment for laboratory applications and, as well, to use in automated measuring systems with computer-control, such as goniophotometers. It meets all requirements for class L-illuminance meters according to DIN 5032 part 7.
