TDS METER MODEL AD-410 .

AD410 Is Portable microprocessor-based instruments for measuring TDS, and temperature.

The autoranging feature of the TDS readings automatically sets the
instrument to the scale with the highest resolution.
Measurements are compensated for temperature effect automatically
(ATC) or manually (MTC). The temperature compensation feature can also be
disabled to measure actual TDS.

The temperature coefficient is user selectable. The instuments also
feature a measurement stability indicator.

Supplied complete with A76309 conductivity probe with built-in
temperature sensor and 1 m cable, batteries (4 x 1.5V AA alkaline)
and instruction manual.
