Product information "Sauter SP 200K LED light meter, up to 200,000 lx, rotatable sensor unit"
The Sauter SP 200K measures the illuminance of workstations and, according to Kern, can also handle LED lighting, as the photo sensor (silicon diode) is filtered. The handheld unit has the sensor unit mounted on the housing, which can be rotated by +90° and -180° to align the sensor with the light source. Four measuring ranges extend up to 200,000 lx, with a readability of 0.1 lx to 100 lx. The display switches between lx and fc at the touch of a button.
Filtered sensor and cosine correction
The photo sensor is a filtered silicon diode; Kern specifically states that the device is also suitable for LED lighting. Cosine correction compensates for obliquely incident light. The sensor unit can be rotated by +90° and -180° and thus aligned with the light source.
Accuracy according to Kern
Up to 20,000 lx, the measurement accuracy is ± 4 % of the result plus 10 digits, from 20,000 lx ± 5 % of the result plus 10 digits. Kern specifies the repeatability as ± 2 % of Max and the temperature error as ± 0.1 % of Max per °C. The sampling rate is 2 Hz. The addition "+ 10 digits" means that ten steps of the smallest display increment are added to the percentage deviation.
Data hold, track and tripod
With the data hold function, pressing a button freezes the current measured value until the button is pressed again. The track function continuously records changing conditions. There is a ¼-inch thread on the back for a tripod, so you have both hands free during longer measurements. The LCD has 16 mm high digits; according to Kern, the 9 V block battery lasts up to 200 h. A sturdy protective cover protects the sensor.
Measuring ranges
The device measures in four ranges. The readability becomes coarser with the range.
| Measuring range (Max) | Readability (d) |
|---|---|
| 200 lx | 0.1 lx |
| 2,000 lx | 1 lx |
| 20,000 lx | 10 lx |
| 200,000 lx | 100 lx |
Typical applications
- Building services: measuring illuminance in offices and corridors
- Industry and manufacturing: checking the illumination of production workstations
- Agriculture and plant breeding: measuring light conditions in greenhouses
- Road construction and traffic engineering: checking street lighting
- Lighting technology and luminaire manufacturers: compare LED luminaires and systems
Those who need a device with a remote sensor will find it in the SO 200K. The SV 100 covers up to 400,000 lx and transmits data via Bluetooth.
