Comark C9503 ATEX Intrinsically Safe Pressure Meter - 0 to ±350mBar

This meter has been designed with Ex II 1 G EEx ia IIC T4 Baseefa 03 ATEX 0079 certification. Please check that the environment you’re working with is suitable for this meter.

Fully intrinsically safe pressure measurements are easily obtained using Comark’s C9503, a comprehensive pressure meter designed not to cause an ignition in a potentially combustible environment.

Part of the C9500 range, the C9503 features the ability to calculate pressure from 0 to ±350mBar across selectable pressure units of PSI, mBar, inH20, inHg, mmHg, torr, Kpa and mmH20. Both positive and negative (vacuum) pressure measurements can be carried out.

Comark C9503 ATEX Intrinsically Safe Pressure Meter Key Features

• Certified for use in environments with combustible atmospheres in line with Ex II 1 G EEx ia IIC T4 Baseefa 03 ATEX 0079 certification (certification applicable at atmospheric pressure)
• Impregnated protection: limits electrical discharge and surface discharge to prevent ignition of volatile gases, dust or vapours
• Pressure range: 0 to ±350mbar
• Selectable pressure units: PSI, mBar, inH20, inHg, mmHg, torr, KPa and mmH20
• Twin inputs for gauge or differential pressure measurements 
• Positive and negative ports for positive or negative (vacuum) pressure measurements
• Adjustable zero values
• Max, min and data hold functions
• Average reading function
• Filter mode removes transients readings and takes the average reading over the past four seconds
• Record function 
• Overrange indicators – maximum over/under pressure 15PSI/1000mBar
• Indicates when measurements are in excess of 9999
• Selectable auto switch-off function
• Low battery indicator
• Supplied with a 9V PP3 6F22 battery 
• Long battery life: up to 125 hours of continuous use
• Supplied with 4 x 1/8" BSP nylon washers, 1.4m polyurethane tube and 2x male stud coupling with washer
• Ultra-tough housing: dust and waterproof to IP67
• Functions as a calibrator (requires Comark TK2 pressure test kit)
