TEK J17 Photometer
Features
The Tektronix J17 and J18 are handheld digital Photometers/Radiometers/Colorimeters
for the laboratory, field or production area. A J17/J18 System consists
of a J17/J18 handheld meter and one of seven interchangeable heads. At
the heart of the J17/J18 is a microprocessor capable of performing several
functions: Metric-to-US conversion, auto-range, auto zero, hold and conversion
between color coordinate systems. The J17/J18 can be used with a PC for
automated testing and data recording. The J17/J18 are powered by a 9-volt
battery.
Plug-in Heads Provide Measurement Flexibility
Pre-calibrated plug-in heads measure illuminance, luminance and color
using CIE coordinates (u' v' or xy). All heads use spectrally corrected
silicon photodiodes with multi-element glass filters for long-term stability
and accuracy. Connection of a head to the J17/J18 automatically selects
the correct measurement units. The backlit liquid crystal display can
be read easily in dark locations.
