It uses a gold cathode, silver anode, FEP Teflon membrane and half-saturated KCl electrolyte. The temperature range is -5 to 45°C, with ±0.2°C thermistor accuracy and 0.8V nominal polarising voltage. Nominal probe current is 19µA in air and 0.15µA or less in nitrogen at 30°C. Typical DO response is 90% in 15 seconds at 25°C, or 45 seconds at low DO; temperature response is 95% in 45 seconds at 50°C. Tested above 65°C within ±5% of nominal. Includes wetting cap, sodium sulphite and service kit; cable is not included.\u003c\/p\u003e","brand":"TPS","offers":[{"title":"Default Title","offer_id":51325486432292,"sku":"EDSEN-123204","price":1575.1,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/3507\/2548\/files\/tps-dissolved-oxygen-sensor-wp-aqua-smartchem-1.png?v=1788163958","url":"https:\/\/globallabsupplies.com\/products\/tps-dissolved-oxygen-sensor-wp-aqua-smartchem","provider":"Global Lab Supplies","version":"1.0","type":"link"}
