Feature: 1. It is the real smart UV energy meter with a large LCD to display the temperature and irradiance curve directly. 2. It is equipped with a USB port, and the computer software can read the record data, drawing curves and print out testing reports. 3. It has a high precision fast response temperature sensor and can measure the real temperature in the curing machine dynamically. 4. It has a built-in heat resisting sheet, can resist high temperature and operate at 100ºC for long time. 5. A built-in large memory and can record irradiance data up to 60,000 and temperature data up to 3800. 6. The stored data will not be lost when the the power is off and the last test data will be displayed automatically when power is on; the test data can only be deleted manually. 7. It is with high accuracy, and has passed many tests of authoritative testing organizations and got certificates. 8. It is with a built-in timer, and can record the UV curing time accurately.
