Temperature/humidity chart recorders and Type K thermocouple remote-sensing chart recorders are optimized for different humidity and temperature ranges. Users are able to interchange 24-hour, 7-day, or 31-day charts as desired, opt to display temperature or humidity, and specify preferred traceable calibration methods. The compact and durable enclosure is smaller than previous models from the company. Large digital displays are viewable from 20'' distances. Other features include audio and visual alarms; large 8" charts; remote probes for tight locations, clean rooms or incubators; dewpoint recording and display; and flip-up pen arm to ease chart and pen changes.
