DULCOTEST® Dissolved Oxygen Sensors

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
