【Descriptions】
The data loggers are ideal for monitoring temperature(or humidity).
User installs USB driver and DGraph software that run under Windows XP, Vista, 7, 8 or 10(32 bit and 64 bit Versions). and use the software to setup sample rate, high/low alarm limit and start/stop method , and download data to PC, etc. And then view, analyse and print the data, or export other file formats(txt, xsl, csv, bmp, jpg).
Especially, in professional applications, user can set access password, name each channel, enable/disable specified channel, input calibration data for each channel, disable LED indication for saving power, and select sample mode(Instant, Average, Maximum and Minimum), etc.
