DULCOTEST® Dissolved Oxygen Sensors
Our product family DULCOTEST® Sensors for Dissolved Oxygen offers two sensor series in various designs and measuring ranges for the solution of your measuring task.
Sensor types
- Type DO1: bar-shaped sensor for simple installation in standard dip pipes in various applications e.g.
fish farming, waterworks and environmental control. Measuring range 0-20 mg/l - Type DO2: Self-cleaning swimming bowl, especially for the control of oxygen input in the activated sludge tanks of purification plants. Measuring range 0-10 mg/l
Advantages
- Efficient process guidance through precise amperometric realtime measurement
- No disturbance through clouding or coloration thanks to amperometric measuring principle
- Pollution insensitive PTFE diaphragm
- Stable zero point thanks to diaphragm-covered extensive electrodes
- No disturbance through temperature-influence thanks to integrated temperature compensation (Pt 1000)
- Reduced dependence on flow and cross sensitivities through diaphragm-covered electrodes
- Automatic diaphragm rupture signaling
- Direct connection to programmable logic controller (PLC) through electrically isolated, calibrated and temperature-compensated 4-20 mA signal
- Fast commissioning through short startig time
- Long lifetime thanks to diaphragm-separated electrodes from process surroundings as well as defined electrochemical conditions through electrolyte
- Easy and cost-efficient regeneration of sensor through replacement of sensor element via bayonet catch (every 2 to 3 years)
- Short delivery times enable near-term replacement
