Our BARTON chart recorders are renowned for the accurate, reliable measurement and recording of pressure, differential pressure (DP), and temperature. Their fully mechanical operation is independent of external utilities that facilitates a low installation cost or portability.

Our Model 202E differential pressure chart recorder is a 12" chart recorder thatis available in one- to four-pen configurations (DP plus three additional temperature or pressure pens) The DP pen is actuated by a BARTON 199 DPU, with features such as over-range protection and pulsation dampening for stable cailbrations even under extreme variations in line pressure and ambient temperature. Optional NACE material selections are offered. Model 242E The BARTON 242E is a 12" chart temperature and pressure recorder offered in one- to four-pen configurations. The BARTON J8 is a 8" chart temperature and pressure recorder offered in one- or two-pen configurations.

The standard temperature system in all Barton Chart Recorders comprises of a factory sealed sensing system that uses a non-toxic fill fluid that converts temperature to mechanical motion. Each temperature recording pen includes a built-in correction for ambient temperature influences. The sensing system is offered in various lengths to support remote mounting of the recorder.
