The High Precision TR-74Ui-H Four Parameter Data Logger achieves a temperature measurement accuracy of ±0.3°C (between 10 to 40°C) with an overall range of -30 to 80°C. The humidity measurement accuracy is ±2.5% (at 25°C, 10 to 85% RH) with an overall range of 0 to 99% RH. The unit has a large data capacity which can store up to 8,000 readings times 4 channels for a total of 32,000 readings in one-time or endless recording mode. By connecting to a computer via USB port, the recorded data can be quickly downloaded with the easy-to-use software. The Illuminance UV Recorder can simultaneously measure and record four parameters: illuminance, ultraviolet light (UV), temperature and humidity. In addition to these parameters, the unit is also capable of displaying cumulative illuminance and cumulative amount of ultraviolet light in the LCD display.
