The DR4300 10" circular chart recorder is a one- or two-pen microprocessor-based recorder that can handle a variety of process parameters from devices such as temperature, humidity, pressure and flow transmitters. It uses pre-printed charts and fiber tip pens and is available with and without a digital display. Easy to operate and maintain, it is ideal for most process recording applications that can be handled by low-cost analog recorders. The Basic DR4300 has a typical accuracy of 0.50%, while the DR4300 recorder with display can be field calibrated to improve the typical accuracy to 0.2%. This circular chart recorder also supports PID control and alarming for those processes that require both recording and control in a single device.
