Sentinel electronic chart recorder (1, 2, or 3 pens) is a low-maintenance instrument built for rugged conditions and designed for flexibility, with programmable channels, which can be installed and calibrated quickly, maximizing your productivity.

Chart recorders are used to document measurements of various physical parameters, such as temperature, pressure, humidity, flow rate, and voltage over time. They operate by using a pen or stylus to mark measurements on a moving paper chart. This paper chart moves at a consistent rate, providing a continuous record of the data, which can later be analyzed.
