  • Industrial Hygiene
  • Occupacianal Health & Safety
  • Product Quality Control
  • Laboratory Research

  • Data logging ability allows user to log 500 samples.
  • Simple cleaning mechanism for easy maintenance.
  • RS232C port available as standard.
  • Back-lit display.

  • While conventional dust meters "count" particulates, the Piezobalance dust meter "weighs" mass concentration of particulates.
  • Data can be reviewed on-screen, printed or downloaded to a computer.
  • Software included for easy data download and processing.
  • Easy operation requires no special training.

As air sample enters the system, it travels through the impactor, which captures and removes larger particulates away from the sample. Smaller particulates become electrically charged and deposited on the piezo-crystal. The total mass of the deposited particulates affects the piezo-crystal’s frequency. Since the change in frequency is proportional to the mass of the particulates, the actual weight of the particulates is obtained.
