APPLICATION
These data loggers are mainly used in monitor and verify temperature/humidity-sensitive goods, equipment or areas. 
Example: 
Cold Chain        Refrigeration       Transportations      HVAC       Food & Pharmaceutical Warehouse Laboratories     Aircraft cabins     Agriculture and Livestock       Environmental monitor
 
DESCRIPTION
These data loggers can measure and store up to 32,000 temperature and humidity readings. Logger status, alarm indication and low battery indication are via flashing red/green LED and yellow LED. The button on housing can be used to start logging, or confirm and clear LED alarm.
User can plug data logger straight into PC’s USB port without any cables. Before getting started, user needs to install USB driver and DGraph software, provided on a CD which is included in product packing box. All the software can run under Windows XP, Vista, 7, 8 or 10 (32 bit and 64 bit Versions). User can easily use DGraph software to setup sample rate (from 2 s to 24 hours), high/low alarm limit and start/stop method, and download data to PC, etc. And then user can view, analyze and print the data, or export other file formats (txt, XSL, CSV, bmp, jpg).
Especially, 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.
