FEATURES
Applications for industrial vibration monitoring : All industrial machinery vibrates. The level of vibration is a useful guide to machine condition. Poor balance, misalignment & looseness of the structure will cause the vibration level increase, it is a sure sign that the maintenance is needed.
Pen type digital vibration meter, vibration sensor is built in, all in one.
Acceleration, Velocity measurement, RMS measurement value.
Metric & Imperial display unit.
Frequency range 10 Hz - 1 kHz, sensitivity relative meet ISO 2954.
Microcomputer circuit, intelligent function, high accuracy.
LCD display, easy read out.
Complete set with the Test pin and the Magnetic base are the standard accessories.
Built-in low battery indicator.
Heavy duty & compact housing case.
IP65 protection.
Compact size, light weight.
Soft carrying case is the optional accessory
