The logger collects measurements of dissolved oxygen with an accuracy of +/- 5% and temperature to +/- 0.1 degrees C. Temperature range is 0 to 35 degrees C with an accuracy of +/- 0.1 degrees C. Oxygen range is 0 to 150% saturation.</p><p style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px; margin-bottom:1.5rem; margin-top:0px;'><strong>Maintenance:&nbsp;</strong>Probe maintenance and download occur monthly.</p><p style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px; margin-bottom:1.5rem; margin-top:0px;'><strong>Point of Contact:</strong>&nbsp;<a style='color:rgb(0, 97, 155); font-family:inherit; text-decoration-line:none;' href='mailto:waterinfo@daera-ni.gov.uk' target='_blank' rel='nofollow ugc noopener noreferrer'>waterinfo@daera-ni.gov.uk</a></p><p style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px; margin-bottom:1.5rem; margin-top:0px;'><strong>Please Note:</strong>&nbsp;Date format in the download is month, day and year.</p></div>
