Circular Chart Recorder
– CR6″ No Display
CR2010 series of circular chart recorders are available in 3 different sizes of the charts i.e. 4”, 6” and 11”. If you want better readability in small space, this 6” chart recorder is a perfect fit. These recorders are widely used in low temperature equipment, blood banks, incubators and any more places. It takes direct inputs from RTD Pt-100 / process inputs like 4-20mA. Standard chart speed available are 4Hr/ Rev; 24 Hr/ Rev and 168 Hr / Rev (7Days/ Rev). 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 200 x170 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. Other power supply inputs are also available.
