With Data Clean’s 2-channel digital temperature sensor you can attach the screen (channel 1) to the front of your server cabinet while the corded channel 2 can be mounted anywhere temperature information is needed. You may require an input and an output reading, upper/lower input reading, or an input and inside the cabinet reading. If you have glass door cabinets, knowing the inside temperature could be critical to the operation and performance of your servers inside those cabinets so mounting channel 1 on the outside and channel 2 inside will keep you up to date on what is going on inside that cabinet. Where ever you decide to mount each channel the temperature monitoring unit will provide the temperature information you need to help you maintain your critical equipment.  Only $12.00 per unit and if you order 20 or more units, installation is included.
