EH Recorder

                                              EH Recorder 

Overview

EH Recorder is a highly reliable recorder produced by using information accumulated for many years and introducing Z new electronic technology and precision machinery.

According to various combinations, there are more than 900 models for selection. The recording methods include single pen, double pen and three pen writing, and line punctuation from 6 to 12 o'clock and 24 o'clock; Adjustment modes include 2-position, 3-position and PID; The alarm modes include upper limit type, lower limit type and upper and lower limit type. With these combinations, we can provide the high-quality recorders we are looking forward to. It is used for all temperature, pressure, flow, meteorological observation, measurement and control.
