Maintenance and Storage
Turbidity and Total Algae Sensors
Turbidity and Total Algae Sensor Maintenance
Clean the sensing window with a non-abrasive, lint-free cloth ( Figure 64 ).
NOTICE: Clean the window carefully to prevent scratches. If
necessary, use mild soapy water.
Turbidity and Total Algae Sensor Short-Term Storage (Less
Than 4 Weeks)
When in regular field use, the turbidity and total algae sensors can remain
installed on the bulkhead in an environment of water-saturated air
(
Figure 65 ).
NOTE: The turbidity and total algae sensors can be stored dry if
stored separate from other sensors.
Place approximately 0.5 in (1 cm) of any water (tap or environmental) in
calibration cup.
Install the calibration cup on the bulkhead and firmly tighten to prevent
evaporation.
Turbidity and Total Algae Sensor Long-Term Storage
Store the turbidity and total algae sensors in dry air. The sensors can be
left on the bulkhead or removed for storage.
If removed from the bulkhead, install the shipping cap on the sensor to
prevent scratches or damage to the optical sensing window.
NOTICE: Install a port plug into the empty port on the bulkhead.
