Digital Test Pressure Gauge LDM 70

Digital Test Pressure Gauge LDM 70 battery powered LDM 70-E25: Accuracy ± 0.25% f.s. LDM 70-K50: Accuracy ±0.5 f.s. Datasheet Operating Manual

• Battery powered
• Rugged, rotatable housing (DS 70 mm)
• 4 1/2-digit LC display (digit height 11 mm)
• 6-digit additional display to thow the selected pressure unit (height 7.5 mm)
• Pressure unit switchable (depending from instrument's range: PSI-bar-mbar-mWC-inHg-cmHg-mmHg-kPa-MPa)
• Easy configuration via three push buttons
• Ranges from 0/1.45 psi to 0/8700 psi
  (0/100 mbar to 0/600 bar)
• MIN and MAX value storage

The digital test pressure gauge LDM 70 are available as complete pressure calibration kit (case, with calibration hand pump LPP 30). The calibration hand pump LPP 30 generates pressure up to 500 psi (35 bar), switchable to vacuum generation -28 inHg.
