Sense and Dispense was developed to meet an urgent need to help stop the spread of germs during the coronavirus pandemic. It includes an alcohol-based 16 oz. hand sanitizer that kills 99.9% of the most common germs to help promote well-being throughout homes, offices, and facilities. To use, simply extend your hand under the device and a sensor activates the dispensing of a refreshing, blue gel in the correct dosage needed for optimum hand hygiene. Refill bottles are easy to attach and provide over 400 dispenses. The automatic dispenser is powered by 4 AA batteries.
