The OXYBase\u00ae WR-RS485-AO combines an optical sensor type PSt3 and electro-optical module in one probe. The sensor has a maximum measurement range of 0 – 100 % O2, and a detection limit of 0.03 % O2 \/ 20 ppb. As it is waterproof, this probe is ideally suited for e. g. measurements in aquaculture or environmental research projects. OXYBase\u00ae is connected directly to the control unit, uses RS485 as digital interface (PreSens proprietary) and has 4 – 20 mA analog output. A serial communication protocol is offered for data exchange between the OXYBase\u00ae and a PC or other host unit. For initial operation and adjustment of the 4 – 20 mA output the PreSens EOM-STS software can be used. The probe is available with various cable lengths, and its sensor is integrated in a removable sensor cap (OEC), which can easily be exchanged. These exchange caps are offered in different versions for certain demands (fast response time, safe for food applications, for aggressive environments, USP Class VI compatible). The sensor is not autoclavable.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
