Short facts: • Long-term stability due to the optical measurement principle D S S O 2S 001-002 E N Versi on: 3.0 S tatus: rel eased, subj ect to al terati ons • Measurement range 0 - 20 mg O2 per l / 0 - 200 % saturation • Temperature sensor included • Minimum of maintenance • Exchangeable cap • Ideal for aquaculture applications Minimal maintenance reliable oxygen measurements. Technical Information Dimensions Measurement range Dissolved Oxygen Temperature Accuracy Dissolved Oxygen Temperature Due to optical measurement principle, the sensor does not need to be refilled with consumeables and has no expendable parts, except the sensor cap, which can be easily replaced after years of operation. Response time Power consumption Cable length This makes the SENECT Oxygen Sensor O2S perfectly suitable for many applications, especially for regulation of the oxygen concentration e.g. in aquaculture or for monitoring. with all SENECT Control units Protection class The SENECT Oxygen Sensor O2S measures the concentration of dissolved oxygen in water reliable with a minimum of maintenance. Based on the principle of optical luminescence quenching, the sensor inspires with accruate and long-term stable measurements and does not depend on flow. Made in Germany. SENECT Gmb H & Co.
