Page 8: Operation
Dissolved Oxygen Measurement In order to obtain reliable measurements, the Turtle Tough sensor must be placed in a position where the natural approach flow amounts to a minimum of 30 cm/s. If there is no natural approach flow, it will be necessary to create an artificial flow. This can be done as follows: •... -
Page 9: Calibration
Calibration Calibration Verification Check Every instrument leaves our manufacturing facility in a calibrated condition after going through a test programme of several hours. The user should nevertheless re-check the calibration since a change may have occurred due to long transport or storage periods. For a fast routine check it is sufficient to have the sensor in atmospheric air. -
Page 10: Sensor Maintenance
Sensor Maintenance The M4S TOUGH Dissolved Oxygen Sensors are extremely corrosion, vibration, and knock resistant, due to their design and construction. • The sensor body (6) and most other sensor components are made of plastic material suitable for recycling. • The visible cathode (3) consists of fine silver in the case of the “active”... -
Page 11: Storage Of The Sensor
Storage of the Sensor When a sensor is not being used for a longer period of time, it is recommended to store it in water, where it should be immersed up to the beginning of the cable. This prevents evaporation of the electrolyte and guards against loss of membrane elasticity. -
Page 12: Replacement Of The Cathode Membrane
Replacement of the Cathode Membrane The cathode membrane has to be replaced immediately in cases where over- pressure during refilling of the electrolyte has led to a shift in the position of the membrane, or where the sensor has not been stored in water over a longer period resulting in a loss of membrane elasticity. -
Page 13: Sensor Refurbishment
Sensor Refurbishment Refurbishment is recommended every six months and also whenever the membrane has been damaged. The refurbishment procedure involves both electrolyte replacement and membrane replacement. This ensures that no foreign substances can get into the electrolyte in the case of a damaged membrane. Steps for replacing the electrolyte and the cathode-membrane: 1. -
Page 14: Pressure Compensation Membrane Replacement
Using the Membrane Positioner Use the Membrane Positioner TT-TOUGH-DO-MP to easily replace the cathode membrane without any wrinkles. Follow these steps for replacing the membrane using a Turtle Tough Membrane Positioner: 1. Pull off the frame. 2. Put the Positioner on a table. -

Page 16: Warranty
Shelf Life Warranty The standard shelf life for a Turtle Tough sensor is one year from the date of shipment. Sensors stored longer than this period may still be functional but are no longer under warranty. Sensors should be stored in a cool, dry location with the sensor tip (where the pH/ORP element is located) oriented toward the ground. -
Page 17: Return Goods
IMPORTANT: Ground loops, poor earthing and faulty electrical installations are a common cause of sensor damage. If you are experiencing unusual or erratic readings, please refer to our support document on ground loops. Damage to Cables and Connectors Please note that integral sensor cables, connectors and plugs must NOT be cut, removed or modified in any way. Sensors contain sensitive internal electronics and our cables and connectors are designed to protect the integrity of these components.
