Digital Pressure Gauge LEO-Record

製品詳細

Product Description

The high-accuracy LEO-Record digital manometers can record pressure and temperature autonomously for long periods thanks to their memory function. The data logger can be connected to a computer via the RS485 interface for configuration and for reading out the recorded data. The current pressure value can be displayed in a wide variety of units of pressure. Power is supplied by a high-quality 3,6 V lithium battery.
