PROBE DEPLOYMENT
Guidelines for Installation & Sampling Site Maintenance
• Select a water-sampling site that will allow collection of representative water samples.
• Position the probe so the sensor surfaces face toward the flow, this will minimize air bubble or fluid
cavitation. Limit flow rate to moderate.
• Mount the probe at a 0 to 45° angle. This will prevent the pH (pH/ORP) sensor from becoming
electrically discontinuous due to internal electrolytes flowing away from their internal cells.
• Ensure sampling sites have easy access.
• Regularly visit water sampling sites to check for damage to sensors, the installation mountings,
and the meter battery power.
• Remove aquatic weed growth that may be interfering with water sample collection.
• Position suspended probes behind a support and anchor the cable/probe to a pipe to protect against
debris.
• Have access to spare sensors and calibration standards or buffers.
• Strictly follow the established standard operating procedures (SOPs).
• Avoid trapped air and maintain constant flow rate if installed in a flow cell.
