Aqua TROLL 500 & Aqua TROLL 600 pH/ORP Sensor
Part Number 0063470

Description

The pH/ORP sensor is a combination, single-junction electrode
that contains a platinum ORP sensor, a glass pH sensing bulb, a
replaceable junction, and refillable reference electrolyte
solution. The sensor is designed and manufactured for long-
lasting, accurate results in a variety of environmental waters.

Installation

1. Remove the restrictor or cal cup from the front end of the
instrument. This allows access to the sensor block.
2. Remove the black storage cap from the sensor and save it
for future sensor storage.
Salt crystals may form on pH/ORP sensors during
storage. These crystals are normal and do not
impact sensor performance.
3. Rinse the sensor with clean water.
4. Remove any moisture or dirt from the instrument and
remove the port plug or other sensor from the sensor port.
Retain the plug for future storage.
5. Remove the dust cap from the sensor connector. Check
lubrication of the O-rings. If the O-rings appear dry, apply a
small amount of silicone lubricant, provided in the sensor
box, before installation.
6. Insert the sensor into the sonde and push until it is fully
installed and flush.
Notice the blue sensor interlock grooves on the
wiper motor. You must install the sensors so that
they slide into the grooves.

7. Use the Allen wrench to tighten the screw at the base of
the sensor. Do not overtighten the screws.

Calibration

The pH/ORP sensor requires separate calibrations for pH and
ORP.
ORP
A 1-point calibration in a solution with known potential at a
given temperature is sufficient to calibrate ORP. Use Quick
Cal or ZoBell's solution for a 1-point calibration that calculates
the sensor offset, or use default coefficients in the software to
reset the factory defaults.
pH
Although pH may be calibrated with Quick Cal (1 point at pH
7), In-Situ recommends a 2- or 3-point calibration. Use
calibration solutions closest to the pH range you expect to
measure. The Default Coefficients option resets factory
defaults to the sensor. No solutions are required.

Sensor Calibration Procedure

For proper calibration procedures for all sensors, please
consult the instrument manual.
