For Go Direct ISEs (order codes begin with GDX-), simply enable the sensor’s mV channel in the app.<\/p>\n
For most LabQuest ISEs (order codes end in -BTA), there is an experiment file within Probes & Sensors–>ISE folder in Logger Pro<\/i> (version 3.4 or newer) that converts the output to mV. (Note: There is not an experiment file for the Potassium ISE. See the equation option below.)<\/p>\n
If you are using software other than Logger Pro<\/em>, the mV output of the electrode can be calculated\u00a0using the following equations:<\/p>\n For the Nitrate ISE, the equation that converts mg\/L to mV is: For the Chloride ISE, the equation that converts mg\/L to mV is: For the Calcium ISE, the equation that converts mg\/L to mV is: For the Ammonium ISE, the equation that converts mg\/L to mV is: For the Potassium ISE, the equation that converts mg\/L to mV is: These equations provide the mV output of the electrode, before amplification. If you want post-amplification Volts, the equation is:<\/p>\n V = 0.00727*mV + 1.223<\/p>","protected":false},"excerpt":{"rendered":" For Go Direct ISEs (order codes begin with GDX-), simply enable the sensor’s mV channel in the app. For most LabQuest ISEs (order codes end…<\/p>\n","protected":false},"author":11015,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[],"tags":[1565,1564,1566,940],"class_list":["post-1296","post","type-post","status-publish","format-standard","hentry","tag-calcium-nitrate-ammonium-chloride","tag-ise-ion-selective-electrode","tag-mv-amplify-amplification","tag-voltage"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/1296","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/users\/11015"}],"replies":[{"embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/comments?post=1296"}],"version-history":[{"count":0,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/posts\/1296\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/media?parent=1296"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/categories?post=1296"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.vernier.com\/til\/wp-json\/wp\/v2\/tags?post=1296"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
