Larson Davis HVM 100


HVM 100Human Vibration Meter £ 32 a day *

Small, battery operated, 3-channel analyser to measure Hand-Arm and Whole Body vibration exposure levels, plus general purpose vibration analysis. The HVM - Human Vibration Meter is supplied in some markets as the IHVM - Industrial Hygiene Vibration Monitor.

  • Features
  • BS ISO 2631, BS EN ISO 5349, BS 6841 and BS EN ISO 8041 standards fulfilled
  • Frequency weightings for hand-arm and whole-body vibration measurements
  • Simultaneous 3-channel measurements: X, Y and Z
  • RMS and Peak levels
  • Additional 4th channel calculates the resultant sum of the X, Y and Z levels
  • Measures and stores up to 200 hours of time histories for each channel
  • Non-volatile memory
  • Serial printer output
  • Serial interface to PC
  • IEC type LR6 [AA] batteries
  • Modes of Operation
  • Hand-arm - Vibration White Finger
  • Whole Body and VDV * *
  • Vibration - general purpose
Typical applications include:-
Worker exposure to high levels of vibration
Risk assessment
Hand-tool performance
Effectiveness of anti-vibration gloves and materials
Measurement ranges with supplied tri-axial accelerometer ≈ 5 m/s2 to 50,000 m/s2   *

Description:-
The HVM 100 is a hand-held instrument for measuring human exposure to vibration, performing the relevant calculations and providing overall results on the LCD display. The results may also be stored in the built-in data logger which can hold up to 100 separate time histories and be down loaded to a PC for further analysis and archiving

Measuring all three axis simultaneously simplifies the test setup, testing time and enhances the repeatability and correlation of the measurements. Both Peak and RMS levels of the 3-axis may be stored together with the important vector sum which the HVM 100 also calculates.

The results, current and recalled from the memory may be downloaded to a PC - order the  HVM SW  utility software, if required. Alternatively HyperTerminal an 'Accessories' program in Windows will download HVM 100 files one at a time.

The analyser provides AC and DC outputs for connecting to FFT analysers like the DI-2200 or DAT recorders for archiving 'the raw data' and post processing.


Manufacturer's Specifications


The HVM 100 is delivered with a SEN 020 triaxial accelerometer complete with a CBL 122 cable, a handle and mounting block, an isolation stud/pad, a box of wax and 4 'fixing' ties, together with a CBL 006 PC serial interface cable, all in a carrying case
