Portable Chart Recorder Comes In Three Versions

The CTXL SUPERECORDER series of portable, microprocessor-based universal circular chart recorders consists of three models: temperature and relative humidity; dual-thermocouple input; and dual-process input. Available in white or charcoal gray, the instruments specify temperature and relative-humidity ranges of -17°C to +49°C and 2% to 98%, respectively. They derive operating power from either four D cells or a universal ac adaptor. Features include a 203-mm chart for 1-, 7-, or 32-day recording, a backlit display that monitors minimum, maximum, and average values, front-panel keypad programming, and chart re-scaling via an RS-232 interface. Bench top and wall mountable, the units include built-in chart lights, high and low audible and visual alarms and two relay contacts. In addition, each comes standard with a remote temperature and humidity probe. Base price is $795. OMEGA ENGINEERING INC., Stamford, CT. (203) 359-1660.
