Data Loggers Go Wireless

The RTR-50 series wireless data loggers include temperature, temperature/humidity, and voltage/pulse/event loggers along with a hand-held data collector. Said to be unique, the RTR-57C handheld data collector allows users to download stored or real-time data from the logger via a radio link, eliminating the need to take the logger to a PC. It provides internal storage for 256,000 readings from up to 250 different logging sessions. A USB interface, along with T&D Recorder software for Windows transfers data to a PC and displays it as graphs and tables or exports the data to other programs. The data-logger series includes four models: the RTR-51 with an internal temperature sensor, RTR-52 with an external temperature sensor, RTR-53 with a combined external temperature and relative humidity sensor, and the RVR-52 for measuring voltage, pulse count, or event time. Each model operates in temperatures from -40°C to 80°C and provides up to 16,000 points of data storage. Using an external sensor, the RTR-52 can measure temperatures from -60°C to 155°C. Prices for the RTR data loggers start at less than $200 and for the RTR data collector at less than $500. COMPUTER AIDED SOLUTIONS, Chesterland, OH. (800) 956-4437.
