Additel's 260Ex is an intrinsically safe handheld multichannel reference recorder with 8 different channel configurations.  Armed with Additel’s most versatile and capable handheld, technicians are now able to measure and collect data for pressure, temperature (RTD probes available), barometric pressure and electrical measurement all in one highly portable device. The powerful logging capability and high-level of intrinsic safety make the ADT260Ex the perfect companion for use in the pipeline industry by supporting hydrostatic pressure testing, air leak testing, inlet and outlet pressure testing at pump stations, safety valve and ex-proof membrane testing, wellhead pressure testing, pipeline filter testing, differential pressure transmitter/flow computing testing, as well as routine calibration of pressure devices.

Intrinsically Safe:
The ADT260EX has passed the most stringent ATEX, IECEX, intrinsic safety certifications. Each unit complies with a certification level of Ex ia IIC T4 Ga. This highly qualified reference recorder can be widely used in potentially explosive gas environments, such as oil and gas platforms, refineries, chemical and petrochemical plants, pharmaceutical industry, energy and gas processing industry.

Datalogging Capabilities:

The Additel 260EX includes a sizable built-in automatic recording capability which supports multi parameter logging, trend curve display, local curve observation and statistical feedback. The logged results are stored onboard and can be viewed locally. The data storage capacity is up to 10 million readings (single channel) with a logging interval that is configurable from 0.1s ~ 9999s

8 Channel Combinations: 

Channel 1: Built-in digital pressure module, field switchable
Channel 2: Built-in barometer, which can be calibrated by the user
Channels 3 and 4: External digital pressure module inputs
Channel 5: Simulated differential pressure channel synthesized using channels 3 and 4
Channels 6 and 7: Temperature measurement channels supporting resistance sensors with 2, 3 or 4 wires
Channel 8: Measures current, voltage, frequency, pulse or switch testing. Built-in loop power included.
