Digital Test Pressure Gauge LDM 70 battery operated, accuracy 0.25% or 0.5% f.s.
LDM 70
Digital Reference Test Pressure Gauge LDM 70 LDM 70-E25: Accuracy ±0.25% f.s. / LDM 70-K50: Accuracy ± 0.5% f.s.
• Battery powered, rugged, rotatable housing (DS 70 mm)
• 4.5-digit LC display (digit height 11 mm)
• 6-digit additional display to show the selected pressure unit (height 7.5 mm)
• Pressure unit switchable (PSI-bar-mbar-mWs-inHg-cmHg-mmHg-kPa-MPa)
• Easy configuration via three push buttons
• Ingress protection IP 65
• Ranges from 0/1.45 psi to 0/8700 psi ( 0/100 mbar to 0/600 bar)
• MIN and MAX value storage
The display is continuously rotatable so that a clear readability is guaranteed even in unusual installation positions. The LDM 70 can be operated menu-driven via three pushbuttons. Besides showing information about the nominal pressure range as well as minimal and maximal pressure of the process, several pressure units (PSI, bar, mbar, mWC, inHg, cmHg, mmHg, kPa, MPa) and the position of the decimal point can be set. The instruments zero and span can be recalibrated, the LDM 70 can be set to factory default values via menu.
