General

LEO RECORD is an autonomous battery powered instrument with digital display designed to record pressure and temperature over long periods.

 

LEO RECORD offers 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

- Simple and well structured configuration- and read-out software (Logger 4.x) for PC or PDA

- 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.

LEO RECORD has 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 instrument has the following functions:

ZERO: The ZERO-function allows to set any value as a new Zero reference.

UNITS: 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 plaxe via interface/software.
