DataChart 1250 Paperless Recorder



The Data Chart 1250 Paperless Recorder is a feature rich digital recording system offering 2 universally configurable isolated inputs for measuring DC Voltage, DC Current, thermocouples, RTD's as well as pulse inputs. 4 Internal Alarm setpoints, 2 Alarm Relay outputs and 1 digital control input are all standard. Combining small package size with extreme flexibility make the DataChart 1250 a powerful, yet economical, digital data recording system.

A maximum sample storage rate of 100 samples per second can be set for both channels allowing for capture of short duration process signals anomalies. CompactFlash cards up to 2 Gigabytes in size can be used allowing many data points to be stored over long periods of time.

With intuitive operation, flexible input configuration and large memory capability, the DataChart 1250 is a powerful compact digital recorder.
