Circular Chart Recorder
– CR5” No Display
CR2010 series of circular chart recorders are available in 4 different chart sizes i.e. 4”, 5”, 6” and 11”. For enhanced readability in confined space, the 5” chart recorder is an ideal Choice. This chart recorder is specially tailored to work on both Universal Power supply and Battery as well as only Battery-operated options. These recorders are widely used in low temperature equipment, blood banks, incubators and any more places. It takes direct inputs from RTD Pt-100 sensor. Standard chart speed available are 1 day/ 7 days/ 31 days per revolution. These recorders are microcontroller based. Crystal controlled chart drive ensures accurate chart speed. Stepper motors for both pen and chart drive, ensures no lag and no backlash. With a cutout of 138 x 138 mm and smallest depth, makes it very convenient to use. Transparent polycarbonate door makes the chart visible from distance. They come with universal power supply as a standard feature. The recorder comes with a built-in battery back up to ensure the proper working in case of power failure.
