The Mina dual-mode sensor mixer has four features to meet user needs. The Instant Sensor mode is for regular use; it turns the water on when hands come close to the front sensor and immediately turns it off once hands have been removed. If users need more time to wash, they can activate the Wave Sensor mode. The sensor is on the left. Water is turned on at the wave of a hand. The water will continue to flow until another wave turns it off. The body of the faucet can be easily removed to change the battery and carry out maintenance. Water temperature can be adjusted with a small lever on the right.
