Reflectance/Transmittance Test Set
RT-500
An Integrating Sphere is a hollow sphere which has its interior coated with a paint that is nearly perfectly diffuse or Lambertian and which has extremely high reflectance. Light energy introduced in an integrating sphere is reflected from the wall and distributed uniformly around the interior. A detector which is placed at a hole or 'Port' in the sphere wall sees an output which is completely independent of the angularproperties of the input light. The independence of the output of a sphere from the angular properties of the input and the uniform internal distribution of light make integrating spheres ideal for many uses.

Reflex Reflector Measurement Systems
Photometric Solutions International Pty Ltd
The measurement setup involves using a projector to illuminate the test item, and then measuring the luminous intensity of the light reflected from the test item. The ratio of the luminous intensity emitted by the reflector (in candelas) to the illuminance on the reflector (in lux) is the coefficient of luminous intensity or CIL (cd/lx).

Relay / Magnetic Field Testers
PeakTech Prüf- und Messtechnik GmbH
Ideally suited for checking magnetic fields and the correct function of coils, e.g. Relays and solenoid valves. The magnetic field detector works without contact, so that opening the housing is not necessary in most cases. When a magnetic field is detected, the probe tip lights up permanently blue, with clocked relays in the same cycle as they are controlled. The function of the magnetic field detector can be checked before each measurement with the enclosed test permanent magnet.
