1. Overview
The PUS400G ultrasonic oscillator is an apparatus that composes an ultrasonic cleaner together with
an ultrasonic piezoelectric transducer (vibrator). The PUS400G supplies the ultrasonic vibrator with
operating power via a cable.
The ultrasonic vibrator to be combined with the PUS400G is a vibrator mode of lead zirconate-
titanate-based piezoelectric ceramics.
The ultrasonic vibrator is built in the sensor holder of the pH meter.
