Intrinsically Safe Digital Precision Gauge
LEX1-Ei
The high precision of the LEX1-Ei digital manometers makes them ideally suited to calibration and test applications. The minimum or maximum value since the last reset can be displayed at the same time as the current pressure value in a wide variety of units of pressure. Power is supplied by a conventional CR2430 coin cell battery (provided). Intrinsically safe – suitable for use in explosive atmospheres.
