Supco SL500 data loggers are compact, light weight, and easy to use—making them perfect for many applications. Each logger includes software needed for logger set up, data downloading, and analysis. Loggers can be programmed to record over points once the memory is full, or stop recording. Sampling rates can be adjusted from every 1 second to 9 hours, and start/stop may be manually controlled on the logger or a specific run time may be set through the software. The temperature and relative humidity model (18000-53) alternates display of temperature and humidity every two seconds.
