Exploiting the power and resources of a microprocessor, the company’s Superecorder series consists of four different models of portable universal circular chart recorders: temperature and relative humidity, dual thermocouple, dual process, and pH and (RTD) temperature units. Their front panels host a keypad for programming and a large, bright dual-backlit display. Users can download data via the instruments’ RS-232 interface. Unique features include double-sided chart paper and a magnetic hub. Of note, the temperature/relative-humidity model (CTXL-TRH) also comes with Windows-based software to log data in real time, download recorded data, or re-scale chart paper. There is also a wireless temperature/relative humidity probe available as an option. Price for the recorders starts at $795 each. OMEGA ENGINEERING INC., Stamford, CT. (800) 872-9436.
