Low cost data loggers measure temperature and humidity
A new family of handheld, battery-powered data loggers has been introduced by Measurement Computing Corporation.
The devices utilise an LCD display to show real time readings, graphs of data and current status.
Simple push-button controls are used to start and stop logging, review logger settings, determine memory used and view max and min readings.
The loggers, which are available in the UK from Adept Scientific, also feature LED and audible high and low alarms.
The single-channel USB-601 can collect temperature measurements between -30 and 80C, while the USB-602 can read relative humidity levels as well.
The dual-channel USB-603 offers K, J and T type thermocouple measurements and includes two type K thermocouples.
With the software supplied with all three models, users can select sampling rate, start time and logging mode, and perform data download and analysis. Over 250,000 readings can be stored, with sampling intervals from two seconds to two hours.
