Description

Absolute pressure gauges and ultrasonic leak detectors are useful for improving quality and productivity in the vacuum applications for composites

GDH111-Set absolute pressure gauge (precision pressure gauge for low pressures)

Absolute pressure gauges use the absolute zero of pressure as their reference datum and measure pressure independently of altitude and weather conditions. In composites manufacturing applications, absolute pressure gauges can be used to:

  • Provide faster and more precise leak test (drop test) results
  • Diagnose water and solvent vapour problems causing porosity
  • Identify incomplete or inconsistent laminate evacuation causing dry areas
  • Check vacuum pump performance.

G1111 specification

  • Auto power off
Case
  • Padded carry case included

VPE ultrasonic leak detector

Ultrasonic leak detectors enable small vacuum leaks inaudible to the human ear to be detected and physically located.  Using a leak detector will considerably speed up the location and repair of vacuum bag leaks.

Audio output
  • 0 to 4 kHz (via headset, with volume control)
Display
  • 10 element bar graph
Power supply
  • 9 V DC battery (included)
  • Auto power off
Case
  • Padded carry case included
