PRELIMINARY EXAMINATION
HI 216
is a combination bench meter that can read conductivity in 4
different ranges, and resistivity.
For conductivity measurements, the calibration is a simple 1 point
procedure through the easy-to-operate front panel knob, and the
supplied probe does not require re-calibration when switching from
one range to another.
The 4-platinum-ring probe has a built-in temperature sensor that
automatically compensates for temperature changes, and the tem-
perature coefficient can be adjusted from 0 to 2.5% through a knob
on the front panel.
For resistivity measurements, the meter is factory calibrated and, if
necessary, calibration can be adjusted by acting on the trimmer
located on the rear panel.
The
HI 3316D
resistivity probe is easy to clean and requires little
maintenance. It also features a built-in temperature sensor to
automatically compensate for temperature variations, with an user-
selectable (from 2 to more than 7%) temperature coefficient.
Both probes use the same DIN plug on the rear panel, and the meter
automatically recognizes which probe is connected.
