Digital manometer Model LR- Cal HMG 1 for small pressures, negative pressures and differential pressures

The digital manometer of the LR- Cal HMG 1 offer

  • Cost-effective hand-held instrument
  • Measuring pressure and vacuum pressure differential (positive and negative indicator of overpressure)
  • Optional 0... 1 VDC analog output
  • Ranges from 1 mbar to 10 bar absolute pressure

The digital manometer LR- Cal HMG 1 is suitable for the measurement of non-corrosive and non-ionic Flüssiigkeiten and gases, such as air, dry gases, and hydraulic fluids. Enter next differential and positive and negative pressure, and optionally flow. These process variables are displayed on a 3 1/2-digit LCD display with 12.7 mm digit height, and optionally fed to a 0..1 V analog output.

By using piezoresistive measuring elements have a high reliability and accuracy. Power is supplied by a 9V battery (6F22). Falls below the minimum permissible operating voltage is indicated on the LCD display "low battery". Each unit is supplied with a test certificate.

 

Typical applications:

  • Monitoring air filters and ventilators
  • Level monitoring of liquids
  • Monitoring of air flows
  • Pressure monitoring in clean rooms
  • Medical

Available versions:

  • Type LR- Cal HMG 1: without analog output
  • Type LR- Cal HMG 1-1: with analog output 0...1 V
