Luminescent Dissolved Oxygen Probe: Model LDO10101,
LDO10103, LDO10105, LDO10110, LDO10115 or LDO10130
Safety Information
Read all labels and tags attached to the instrument. Personal injury or damage to the
instrument could occur if not observed.
Overview
Figure 1 on page 2 shows the LDO101 series probe, a luminescent dissolved oxygen (LDO
®
)
probe. The LDO10105, LDO10110, LDO10115 or LDO10130 rugged probe is available with a
5, 10, 15, or 30 meter cable. The LDO10101 or LDO10103 standard probe is available with a
1 or 3 meter cable. The probe provides measurement of the dissolved oxygen concentration in
wastewater, drinking water and general applications. For BOD applications, use the
LBOD10101 probe equipped with LDO technology and an incorporated stirrer.
