In the context of practicing good hygiene, Portable Touch free Soap-cum-Water Dispensing System by CSIR-CMERI is unique in its own as soap and water are being dispensed at a fixed interval from the same tap.

When a person approaches the sensor (IR)on the portable soap-cum-water dispenser, a predefined amount of soap (a few millilitres) will be dispensed from the tap, momentarily. After rubbing his hand for twenty (20) seconds, clean water is dispensed from the same tap. The arrangement aims to reduce wastage of water as well. Internally, the 220 V AC line is used for soap dispensing as well as generating a 12 V DC line for powering the rest of the electronics circuit. The system is currently installed at the CSIR-CMERI main gate and is operational.
