Pipeline and plant tests often run for hours in classified areas, and they need more than one reading: line pressure, a second pressure point, ambient, temperature, and sometimes a transmitter signal. The Additel 260Ex records all of it in one handheld, intrinsically safe unit, certified ATEX and IECEx, Ex ia IIC T4 Ga.

Its 8 channels combine a field switchable Additel 158Ex pressure module, a built-in barometer, two external pressure modules with a synthesized DP channel, two RTD channels, and an electrical channel with loop power. Logging runs from 0.1 to 9999 second intervals, stores up to 10 million readings, and shows real-time trends and statistics on the color touchscreen. Bluetooth and the Additel Link app bring the data to a phone or tablet.

Use the 260Ex for hydrostatic tests, leak tests, safety valve tests, and wellhead or pump station checks. Extend pressure with Additel 161 modules, manage results with ACal 9530, and see the Additel 273Ex for intrinsically safe pressure calibration.
