Product Description

The HT-1201 Split Type Vibration Meter is a portable digital vibrometer designed for routine vibration measurement of mechanical equipment. It uses a piezoelectric ceramic accelerometer to measure vibration acceleration, velocity and displacement, while also providing ambient temperature measurement.

Product Overview

The HT-1201 Split Type Vibration Meter is a compact vibration monitoring instrument for evaluating mechanical equipment vibration. Its split-type construction separates the measuring probe from the main display unit, making it convenient for measurements at different machine locations.

The meter uses a piezoceramic accelerometer (shearing type) and provides measurements in acceleration, velocity and displacement modes. It also supports temperature measurement and provides a clear digital display for viewing readings.

It is suitable for routine condition monitoring, maintenance inspection and troubleshooting of rotating and vibrating machinery.

Key Features & Benefits

  • Three vibration measurement parameters – acceleration, velocity and displacement.
  • Piezoelectric ceramic acceleration sensor for vibration acquisition.
  • Split-type probe design for convenient measurement access.
  • Wide acceleration measurement range up to 199.9 m/s².
  • Velocity measurement up to 199.9 mm/s.
  • Displacement measurement up to 1.999 mm.
  • Separate frequency characteristics for acceleration measurements.
  • Ambient temperature measurement from 0°C to 60°C.
  • Max Hold function for capturing peak vibration values.
  • Digital LCD display for easy reading.
  • Portable battery-operated design.
  • Automatic power-off helps conserve battery life.
