An amperometric measurement of EC\/TDS is based on Ohm&#8217;s Law, I = V\/R where R depends on the distance between two pins and their surface. Oxidation changes both the distance and surface which will affect accuracy. The DiSTs non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results.<\/li>\n<li>When calibration is necessary, simply submerge the electrode tip into calibration solution (5.00 mS\/cm or 12.88 mS\/cm) and adjust the trimmer on the side of the tester.<\/li>\n<\/ul>\n<ul>\n<li><b>EC\/TDS Temperature Compensation :<\/b>Automatic, 0 to 50\u00b0C (32 to 122\u00b0F)<\/li>\n<li><b>EC Calibration : <\/b>Manual, one point<\/li>\n<li><b>Environment : <\/b>0 to 50\u00b0C (32 to 122\u00b0F); RH max 95%<\/li>\n<li><b>Ordering Information :<\/b> HI98304P (DiST4) is supplied with protective cap, screwdriver, batteries and instructions<\/li>\n<li><b>Weight : <\/b>95 g (3.4 oz.)<\/li>\n<li><b>EC\/TDS Probe : <\/b>Amperometric graphite electrode<\/li>\n<li><b>Dimensions : <\/b>175 x 41 x 23 mm (6.9 x 1.6 x 0.9&#8243;)<\/li>\n<li><b>EC Range : <\/b>0.00 to 19.99 mS\/cm<\/li>\n<li><b>EC Accuracy : <\/b>2% F.S.<\/li>\n<li><b>Battery Type\/Life : <\/b>4 x 1.5V alkaline \/ approximately 200 hours of continuous use<\/li>\n<li><b>Cell Type : <\/b>Amperometric graphite<\/li>\n<li><b>EC Resolution : <\/b>0.01mS<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<div>\n<p>HI98304P is rugged and reliable pocket-sized testers that offer quick and accurate reading of Conductivity.
