These 100mm recorders range from the simple analogue recorder to a self contained data acquisition system.

4101: The 4101 is available as a 1 to 4 continuous pen instrument with a 4Hz sample rate (4101C) or as a multipoint instrument with up to 6 inputs plotted (4101M). Access to pen zero and span, alarm thresholds, chart speed, time and date is from the font of the recorder. The use of pre-configured inputs allows direct connection of a variety of transducers. Text annotation can print the time, chart speed and channel scales onto the chart.

4102: The 4102 has all the features of the 4101, but has a digital display in place of the analogue scales. The three-colour screen offers large four-digit indication of the measured parameters, channel identification and alarm status. Input types, alarm set point and instrument calibration can all be adjusted using the operator keypad on the display.

4103: The 4103 is available as a 1 to 4 continuous pen instrument with 8Hz sample rate (4103C) or as a multipoint instrument with up to 6 inputs plotted (4103M). The instrument has the option of a PC card to configuration storage, transfer of process data to computer database or spreadsheet packages. Extensive mathematics capabilities include totalisers, timers, and counters. The 4103’s annotation allows scale and message printing and time lagged numerical values.
