• Operating instructions • Carrying strap 2. System description The Camlab Water CW6230 is a sturdy, water- tight handheld meter designed for daily measurements in the area of field or laboratory analysis. It is used to measure oxygen concentration in surface waters and groundwater as well as for waste water and service water analysis. - Page 5 Camlab CW/6230 2/5/06 3:33 pm Page 5 not just as impact protection but also as a storage compartment for the sensor and as an anti-slip device when the meter is used in an upright position. Microprocessor technology and 4*AA 1,5 V batteries allow unit operation without battery change for 12,000 hours or more.

Page 19: Care And Maintenance
Camlab CW/6230 2/5/06 3:33 pm Page 19 Damaged membrane or air bubbles in the membrane cap cause incorrect results. The membrane cap is listed in the spare parts list. Refill opening: if the sensor is used at excessive tem- peratures or stored outside the storage bottle for lengthy periods of time, this will result in electrolyte evaporation losses. - Page 20 Camlab CW/6230 2/5/06 3:33 pm Page 20 Servicing the sensor: Unscrew the membrane head and wipe off the elec- trolyte solution carefully using a paper cloth. Do not allow the electrolyte to come into contact with your hands. If it does come into contact with your skin, rinse the affected area thoroughly in water.
