Product Description

Product Description

Comprehensive Product Introduction: Fluker 718Ex-300G Intrinsically Safe Pressure Calibrator
1. Product Overview
The Fluker 718Ex-300G is a professional-grade, intrinsically safe pressure calibrator engineered for hazardous environments where explosive gases or dust may be present. Certified for ATEX II 1G EEx ia IIC T4 compliance, it ensures safety in oil and gas, chemical processing, mining, and other high-risk industries. This portable calibrator integrates a precision pressure sensor (-830 mbar to 20 bar) with a 24V loop-powered mA measurement tool, enabling simultaneous testing of pressure transmitters, gauges, and switches. Its compact design (216 × 94 × 66 mm) and rugged holster make it ideal for field use, while the 0.05% pressure accuracy and 0.02% mA resolution deliver laboratory-grade reliability .
