Series RD-87 consists of six models for monitoring Type J thermocouple readings, temperature, temperature/humidity, voltage, current, or 4 to 20 mA input. All have an LCD display and record on a 4"-wide strip chart using a single pen, except for the two-pen temperature/humidity model. The full-function alarm can be set to sound when measurements exceed set limits. To prevent nuisance alarms caused by brief variations, alarm activation can be delayed by a specified amount of time.
