The Oil Quality Display is a simple but powerful device which allows you to read the quality and temperature of the oil from a sensor without a PC. This enables you to set up the display box on site and then be able to see the oil quality and temperature readings as required. Use an Android app to connect your Smartphone with the OQD smart via Bluetooth. With it being IP67 rated (when connected) you do not need to worry about the need to keep it in a dry place. Also with it being made from polycarbonate it is a strong durable product which cannot be damaged easily. The new ‘Rate of Change ‘ feature allows you to easily monitor the degradation of oil over a programmable period of time.
