The Testo Lux Probe is a precision instrument designed to measure illuminance levels in various environments, ensuring compliance with workplace lighting standards. It assesses illuminance according to the V-lambda curve, which corresponds to the sensitivity of the human eye in daylight, making it suitable for all common light sources, including white or warm light LEDs (K< 5,000).
This lux probe is ideal for determining the illuminance in workplaces such as offices, production areas, hospitals, museums, or schools. Its non-slip probe contact surface ensures convenient positioning at the measuring location, and the 1.4-meter cable length allows for measurements without interference from the user's shadow. The clearly structured measurement menu enables intuitive operation, and the intelligent calibration concept ensures exceptional accuracy by requiring only the probe tip to be sent for calibration, keeping the measuring instrument in continuous use.
