Additel 260Ex multichannel reference recorder features 8 channels and can measure and collect data for pressure, temperature, barometric pressure, and electrical measurement all in one highly portable device. The data logging capability and the Intrinsic Safety rating combine to make the 260Ex ideal 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.

The 260Ex's built-in automatic recording capability supports multi parameter logging, trend curve display, local curve observation, and statistical feedback. Store up to 10 million readings (single channel) with a logging interval that is configurable from 0.1s to around 9999s. The logged results are stored onboard and can be viewed locally. 

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.
