Description

LR-Cal Serie 3000 description

The LR-Cal Series 3000 handheld digital pressure gauges measure with a piezoresistive sensor and are suitable for measuring clean and dry gases, e.g. air, nitrogen and many more.

The LR-Cal Series 3000 instruments are used, for example, in laboratories, in quality assurance, by plant engineers, in the heating and ventilation industry, and in municipal and power plants - and more generally in industry for commissioning, maintenance and troubleshooting in pneumatic systems.

Features:

Easy handling, robust, very good performance
Measurement of pressure, vacuum (negative pressure) and differential pressure
(display of positive and negative overpressure)
Measuring ranges from 0...25 mbar to 0...8 bar
Zeroing at the touch of a button
Display in switchable pressure units,
additionally Auto-Range function (display of the measured value in the highest possible display resolution).
Minimum and maximum value memory
HOLD function ("freezing" of the displayed measured value)
Switchable display backlight
Protective cover with magnet included
