Inkless Recorder – CR4″
Inkless chart recorders from G-Tek is available in 4” and 6” chart size formats.
Part of G-Tek’s most popular series CR2010, they offer utmost reliability and versatility at an affordable price. Since the marking on the chart is through the pressurized needle, there is no need to worry about ink being exhausted or replacing the pen. Pressure sensitive papers are used instead of thermal papers to ensure that the marking is retained for longer period of time.
These 4” recorders are widely used in low-temperature equipment, blood banks, incubators and many more places. They come for RTD Pt-100 inputs, 4-20mA/ 0-1v process inputs. Standard chart speeds are 4Hr / 24Hr and 168Hr (7Day) per revolution.
These recorders are microcontroller based. Crystal controlled chart drive ensures the good chart speed accuracy. Stepper motors for both pen and chart drive ensures no lag and no backlash.
With a cutout of 138X138 mm and smallest depth, makes it very convenient to use. Transparent polycarbonate door makes the chart visible from distance. They come with a universal power supply as a standard feature. Other power supply inputs are also available.
