The EH series recorders are supplied with either continuous pen-writing or multi-point dot-printing systems. This versatile series of electronic self-balancing strip chart recorders features a 180mm chart. Models are available to record various industrial variables such as temperature, mV or DC voltage at 1, 2, 3, 4, 6, 12, or 24 points. The measuring systems of mV, thermocouple, resistance thermometer or thermistor are available.
