UL-TECH Sonicheck-15 is a portable ultrasonic sound pressure meter designed for evaluating ultrasonic activity in liquids.

The instrument uses a dedicated immersion probe placed inside a liquid-filled ultrasonic tank. The probe detects ultrasonic signals and transmits them to the handheld instrument for measurement and display.

By conducting periodic measurements at comparable positions and operating conditions, users can monitor changes in ultrasonic activity and identify potential deterioration in system performance.

The Sonicheck-15 supports a measurable frequency range of 20 kHz to 15 MHz, a signal measurement range of 0–500 mV and a resolution of 0.1 mV.

The instrument features an LCD display and is powered by two 1.5 V AA batteries.

The HP-215 immersion probe has a 320 mm probe length, a 1.5-meter cable and a maximum liquid temperature rating of 70°C.
