Peroxides are the primary products of oil oxidation. Their identi-
fication gives useful informations about oil conservation and
rancidity. HI 83730
HI 83730 HI 83730 HI 83730 HI 83730 allows fast and simple analyses of perox-
ides in oil in accordance with the EC 2568/91 method.

Indicates that the instrument is in a
ready state and waiting for the next
command (Timer or Zero).
These prompts indicate the type of power
supply: “Line” (if the external power

The HI 83730 is an auto-diagnostic portable microprocessor
meter that benefits from Hanna’s years of experience as a
manufacturer of analytical instruments. It has an advanced
optical system based on a special tungsten lamp and a narrow
band interference filter that allows most accurate and repeatable
readings. All instruments are factory calibrated.
The auto-diagnostic feature of this meter ensures always optimal
measurement conditions to ensure most precise readings. The
light level is automatically adjusted each time a zero-measurement
is made, and the temperature of the lamp is controlled to avoid
overheating.
