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. |
