COS03 temperature and humidity data logger

Our COS03 USB data logger is a cost-effective solution that can record temperature and humidity data almost anywhere. Using the built-in alarm LED, built-in rechargeable battery, fully charged can work continuously for up to half a year. It’s that simple to set the log recording interval and start time through the recorder buttons or PC software. There are no cables, cradles, or dongles to keep track of. In addition, we have a mini temperature data logger with 80000 readings storage capacity for your optional. Its price is lower and the accuracy is slightly lower than COS03.
