This is a colorimetric based sensor based on a hybrid organic-inorganic polymer cobalt complex. The sensor strip detects the water activity based on the color of the strip upon equilibration with the sample for 15 min at a given temperature range. The accompanying mobile app computes the water activity from the image of the strip at the 15 min equilibration time. The measurement specifications are as follows:
WaterQ App is designed for the BluQ Kit as a main tool in generating results for Water Activity tests.
*Note: App needs constant internet connection through mobile data or WiFi to generate the test result. In case of no internet connection, the captured images will be placed on queue for sending once data connection is obtained.
