Digital Manometer with Record Function- Leo Record & Leo Record Ei

LEO Record is an autonomous battery-powered instrument with digital display designed to record pressure and temperature over long periods. LEO Record Ei is approved per IECEx for use in hazardous areas. Both the piezoresistive LEO Record as well as the capacitive.

LEO Record (ideal for low pressure ranges) offer the following advantages:
  • High measuring accuracy, resolution and robustness
  • High data security due to the use of a non-volatile memory
  • Display of the actual pressure and the record status
  • Recording of the pressure and temperature
  • Software Logger 5 (included in delivery) for  instrument configuration and analysis of measured data
  • Combination of event-controlled recording and interval recording prevents unnecessary data being recorded (i.e. only measuring the pressure changes…)
  • Installation data (and comments) of the measuring station can be stored in the instrument
  • Pressure connection with G1/4” thread (other threads on demand)
The pressure is measured and displayed once per second (shortest interval). The top display indicates the actual pressure, the bottom display shows the record status. All LEO Record versions have two operating keys. The left key is to turn the instrument on, to select the functions and the pressure units. The right key executes the selected function or unit.
The instruments have the following functions:
The ZERO-function allows to set any value as a new Zero reference.
All standard instruments are calibrated in bar. The pressure can be indicated in the following units: bar, mbar/hPa, kPa, MPa, PSI, kp/cm2, (m)H2O RECORD
The record can be started or ended with the operating keys. The configuration of the record takes place via interface/software.
