GENERAL DESCRIPTION
HI 8043 is a portable meter for Dissolved
Oxygen measurements.
It is housed in a lightweight case, with an
easy-to-read LCD.
Dissolved oxygen and temperature measure-
ments can be performed in the field (waste-
water treatment, fish-farming, water analysis,
etc.) as well as in the laboratory without
compromising accuracy.
Dissolved oxygen is indicated in mg/L (ppm)
and the reading is compensated for the tem-
perature effect (ATC).
The dissolved oxygen probe is provided with
a membrane for covering the polarographic
sensors, and features a built-in thermistor for
temperature measurements and compensa-
tion.
