Palintest Kemio Sensors for Chlorine Dioxide/Chlorite
Kemio sensors are quick and intuitive, delivering repeatable and reliable results each time.
Each box of Kemio sensors includes a QR code which is scanned to input the batch information. Each sensor packet then has a barcode which validates the test type, range and expiry date.
This barcode also matches the Kemio sensor to its calibration information; when scanned Kemio will confirm on screen and allow the test to proceed if the calibrations match. This ensures the correct Kemio sensor is used for each test.

Available in pack sizes of 100 & 500
