Envco – Environmental Equipment

Designed with the latest innovations in recording technology, enclosures and functionality, the digital circular chart recorders are slim, trim and simple. Finding a place to install this digital circular chart recorder is easy, with its compact panel depth and short protrusion from the front panel. The digital circular chart recorder's mode switch, located next to the large red LED display, provides two functions.

When in the PROG/CAL/TEST position, the digital circular chart recorder provides access to program parameters, calibration facilities and test functions. Digital circular chart recorder options are matrix selectable and are shipped with default settings.

The versatile MRC 5000 digital circular chart recorder accepts 4-20mA or 20-4mA inputs as well as mVDC, VDC, thermocouple and RTD inputs. Changes in input type are easily programmed in the digital circular chart recorder in the field. With the digital circular chart recorder's universal power supply (90–264VAC line voltage at 50–60Hz), the MRC 5000 can be installed just about anywhere.

Each MRC 5000 digital circular chart recorder ships with a box of 100, 0-100/24 hour,10” charts. Choose from the digital circular chart recorder models and features listed below including: controller version, NEMA 4 case, RS485 communications port and different chart ranges.
