PRELIMINARY EXAMINATION
DiST ® 7 and DiST ® 8 are portable EC/TDS and temperature
meters specially designed for analytical field applications.
These meters provide fast, accurate, on-the-spot measure-
ments, with a unique stability indicator right on the LCD.
All EC/TDS readings are automatically temperature compen-
sated (ATC), and temperature values can be displayed in °C
or °F units.
The EC/TDS conversion factor (CONV) is selectable by the user,
as well as the temperature compensation coefficient b (BETA).
The meters can be easily calibrated at one point.
A low battery symbol warns the user when the batteries are
to be replaced. In addition, the Battery Error Prevention
System (BEPS) automatically turns the meter off for avoiding
erroneous readings caused by low voltage level.
The built-in temperature and conductivity sensors are pro-
tected inside the cell cup.
