Omega Engineering's Strip-Chart Recorders



RD-87 series of six economical strip-chart recorders monitor thermocouple readings, temperature, temperature/humidity, voltage, current or 4-20 mA inputs. All have an LCD and record on a 4-in. chart using one pen, except for the two-pen temperature/humidity model. The full-function alarm can sound when measurements exceed set limits. To prevent nuisance alarms, activation can be delayed by a specified time
