ACR Jnr. Data Logger

The ACR JR. data logger is the easiest to use electronic data logger available. With its precision calibrated internal temperature sensor, all you have to do is place the logger in the field and leave it. Once you have gathered the desired information, simply plug the logger into a PC's serial port and view the logged information. That's it!
