- Page 2 DESCRIPTION The Eutech Probe The probe is a galvanic measuring element, which produces a millivolt output Note that the probe proportional to the oxygen present in the medium it is placed in. It consists of an is available in two upper part with cathode, anode and cable, and a cap with membrane and different versions.

Page 3: Installation
INSTALLATION The Eutech probe is easy to install. It should be placed where there is some movement in the water-1 cm/sec is enough at 7 mg/1 and 13 C. Ensure that the probe does not strike against the tank wall, and do not mount it directly above diffusers etc. -
Page 4: Maintenance
Maintenance The probe’s membrane must be kept free from deposits. All surfaces in a biologically active system will be covered by a film composed mostly of bacteria. This bacteria film acts as a diffusion barrier for the oxygen that must diffuse through the membrane. -
Page 5: Service Procedure
SERVICE PROCEDURE DO Probe membrane replacement and probe renovation All probe types need membrane replacement if the membrane is damaged. Probes used in aquaculture (type 1) may need renovation if, after some years use, it is not possible to calibrate up to the correct value. Other probes should NOT Tighten the cap need renovation unless subject to extreme conditions. - Page 6 A new membrane can easily be fitted to the cap – see the drawing overleaf. The membrane must be flat – if it wrinkles remove it and try again with a new one. It is important that all parts are clean and dry. Neither O-ring nor membrane can be used more than once.
