is available with a 5, 10, 15 or 30 m (16.40, 32.81, 49.21 or 98.42 ft) cable and is
intended for field use. The probe measures absolute mV values in wastewater, drinking
water and general applications.

Preparation for use
To prepare the probe for initial use:
1. If a rugged probe, remove the shroud and probe storage cap (refer to Remove the
shroud on page 11).
2. If a standard probe, turn the probe soaker bottle cap counter-clockwise to loosen the
cap. Remove the soaker bottle from the probe.
3. If a rugged probe, remove the protective tape from the reference junctions (refer to
Figure 1 on page 2). Dispose of the protective tape.
4. If the probe will be used immediately, prepare the probe for calibration or sample
measurement.
5. If the probe will not be used immediately, store the probe (refer to Storage
on page 11).
To prepare the probe for calibration or sample measurement:
1. If a rugged probe, remove the probe storage cap.
2. If a standard probe, turn the probe soaker bottle cap counter-clockwise to loosen the
cap. Remove the soaker bottle from the probe.
3. Rinse the reference junctions and electrode thoroughly with deionized water to
remove the 3 M KCl solution completely. Blot dry with a lint-free cloth.
4. If a rugged probe, make sure that the shroud is installed before field use (refer to
Install the shroud on page 11).
Note: Damage to the sensing elements can occur if the shroud is not installed during field use.
Damage under these conditions is not covered by the product warranty.
