We have two sample experiments available that describe the use of an older model Colorimeter (needing a DIN-BTA adapter) with a LabQuest. One experiment is a Beer’s Law lab and the other experiment is a kinetics lab (absorbance vs. time). These two write-ups will give you the necessary procedural steps for setting up and calibrating the older model of Colorimeter with the LabQuest App.
