The ammonium/ammonia sensor (007255) is gray. Refer to Figure 1.
There is a replaceable sensor cartridge installed in the sensor. Refer to Specifications on page 5 for
the deployment life of the sensor cartridge.
For best results, use the sensor in waters that are pH 4 to 10. Refer to Specifications on page 5 for
measurement interferences.
The sensor cartridge has a depth limit of 15 meters (49 feet). Remove the sensor cartridge and install
the sensor cap before the sonde is deployed deeper than 15 m (49 ft) to prevent damage to the
sensor cartridge. Refer to the illustrated steps in Figure 2.
To extend the life of the sensor cartridge, remove the sensor cartridge and install the sensor cap
when the sensor is not in use. Refer to the illustrated steps in Figure 2.
Note: At pH levels of 6 or less, water contains ammonium (NH4+) and no ammonia. At pH 12 and higher, water
contains ammonia (NH3) and no ammonium. Between pH 6 and pH 12, water contains a mix of ammonium and
ammonia.

2.3 Calibration
CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
CAUTION
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and
national regulations.
Calibrate the sensors before initial use. At regular intervals, do a calibration check to make sure that
measurements stay within the tolerance range. Calibrate the sensors if measurements are out of the
tolerance range. The deionized (DI) water steps must be done for an accurate calibration.
Refer to the Hydrolab Operating Software Manual for instructions on how to do the tasks that follow:
• Start a sensor calibration.
• Start a sensor calibration check.
• Set the calibration mode.
• Select the measurement units shown during calibration and calibration checks.
• Look at the calibration history.
To look at the Hydrolab Operating Software Manual, start the Hydrolab Operating Software, click
Help and select Hydrolab Operating Software Help.
When a calibration or a calibration check is started, the step-by-step instructions for the sensor show
on the display.
2.4 Sensor guidelines
Keep deposits off the sensor for best measurements. Examine the sensor to make sure that there
are no contaminants. Keep the substances shown in Table 1 away from the sensor.
Table 1 Contaminants
Substance Damage
Oil, sediment or biofilms Contaminates the sensor. If the sensor is contaminated, clean the sensor.

2.5 Maintenance
2.5.1 Clean the sensor
N O T I C E
To prevent damage to the sensor, do not use organic solvent solutions (e.g., acetone or methanol) to clean the
sensor. Organic solvents cause damage to the plastic housing and sensor membrane.
N O T I C E
To prevent damage to the sensor membrane, do not use cleaning chemicals to clean the sensor membrane.
Clean the sensor after each deployment to remove unwanted material (e.g., oil, biological growth and
dirt). In addition, clean the sensor before and after calibration.
Adjust the sonde deployment time in accordance with how quickly sensor fouling occurs in the
deployment waters.
1. Clean the sensor with:
• Mild detergent
• Warm water
• Clean, soft toothbrush
Note: Do not use dishwashing liquid to clean the sensor. Dishwashing liquid and household cleaners with skin
moisturizer can put a film on the sensor.
2. Rinse the sensor with clean water.
3. Soak the sensor in clean water for a minimum of 30 minutes.
4. Examine the sensor cartridge membrane. If unwanted material is seen on the sensor cartridge
membrane, use only a soft brush to carefully sweep the sensor cartridge membrane or damage
can occur.
5. Rinse the sensor with clean water.
6. If the substance cannot be removed, contact technical support.
2.5.2 Replace the sensor cartridge
Replace the sensor cartridge when it can no longer be calibrated or if the sensor cartridge is
damaged. Refer to the illustrated steps that follow.

3.2 Product overview
N O T I C E
Do not put the sensor in red pH 4 buffer. Red pH 4 buffer can cause permanent damage to the sensor lenses. As
an alternative, use pH 4 buffer with no color.
The blue-green algae freshwater sensor is an optical fluorometer that determines the concentration
of blue-green algae in freshwater. Refer to Figure 3.
This sensor is sensitive to light. For the best results, point the end of the sensor away from light
sources.

3.3 Theory of operation
The sensor irradiates the freshwater with orange light (590 nm). The blue-green algae in the water
absorbs the orange light energy and gives red light (650 nm). The sensor directly measures the
quantity of red light in the water to determine the concentration of blue-green algae. The reading is
0 to 40,000 ppb (or 0 to 5 V).
3.4 Calibration
CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
CAUTION
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and
national regulations.
Calibrate the sensors before initial use, at regular intervals and after sensor maintenance or
modifications. Periodically, do a calibration check to make sure that measurements are still within
tolerance range.
Refer to the Hydrolab Operating Software Manual for instructions on how to do the tasks that follow:
• Start a sensor calibration.
• Start a sensor calibration check.
• Set the calibration mode.
• Select the measurement units shown during calibration and calibration checks.
• Look at the calibration history.
To look at the Hydrolab Operating Software Manual, start the Hydrolab Operating Software, click
Help and select Hydrolab Operating Software Help.
When a calibration or a calibration check is started, the step-by-step instructions for the sensor show
on the display.
3.4.1 Use a solid secondary standard
Use a solid secondary standard to verify the calibration of the sensor when a calibration check is
done. Refer to Accessories for ordering information.
Use a solid secondary standard only to verify the calibration of the sensor on which the value is set.
Set the value of the solid secondary standard as follows:
1. Make sure that the optical surface of the sensor is clean and dry.
2. Put the sensor into a sample with a known concentration or a Rhodamine Calibration Dye
Solution.
3. Record the sensor output voltage (0 to 5 V).
4. Clean and dry the sensor.
5. Put the solid secondary standard on the optical end of the sensor.
6. Turn the solid secondary standard until it is aligned with the indexing mark on the sensor. A
clicking sound is heard when the solid secondary standard is correctly aligned.
7. Use the supplied screwdriver to turn the screw located on the side of the solid secondary
standard. Turn the screw until the sensor output voltage is the same as the value recorded.
Note: Turn the screw clockwise to increase the voltage. Turn the screw counter-clockwise to decrease the
voltage.
