SpotCheck Plus delivers rapid surface hygiene verification for dairy, beverage, and food processing facilities. This instrument-free colorimetric device detects glucose and lactose residues within 60 seconds, enabling immediate corrective action during sanitation procedures. Ideal for post-cleaning verification and CIP validation, SpotCheck Plus provides semi-quantitative results through intuitive color change: clear indicates pass, green signals residue presence. With sensitivity detecting 2.5 micromoles D-glucose and 5.0 micromoles lactose, sanitation teams can confidently verify cleaning effectiveness without laboratory equipment. The 100% recyclable plastic construction supports sustainability initiatives while the room-temperature stability eliminates cold storage requirements.
