It is the waterproof version of the Oxybase probe.<\/p>\n
The range is 0 – 100 % O2<\/sub>, with a detection limit of 0.03 % O2<\/sub>. These probes are waterproof and can be submerged completely. Furthermore, their stainless-steel housing has an additional plastic cover which offers protection against environmental impacts. This makes the probes ideally suited for long-term outdoor use in e. g. environmental research applications or aquaculture.<\/p>\n These probes have RS485 as digital interface (OXYBase\u00ae WR-RS485-SW = PreSens proprietary, OXYBase\u00ae WR-RS485M-SW = Modbus RTU) and are connected directly to the control unit. A serial communication protocol is offered for data exchange between the OXYBase\u00ae and a PC or other host unit. The probes are available with various cable lengths, and their sensor is integrated in a removable sensor cap (OEC). The sensor is not autoclavable.<\/p>\n Oxygen probe with RS485 interface<\/p>\n","protected":false},"featured_media":30332,"template":"","meta":{"_crdt_document":""},"product_brand":[],"product_cat":[179,245],"product_tag":[],"class_list":{"0":"post-30328","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-measurement","7":"product_cat-oxygen","9":"first","10":"instock","11":"taxable","12":"shipping-taxable","13":"product-type-simple"},"yoast_head":"\nSpecifications<\/h2>\n
