This new model 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 TR-574-H Illuminance UV Recorder can simultaneously measure and record four parameters: illuminance, ultraviolet light (UV), temperature and humidity. In addition to these parameters, the TR-574-H is also capable of displaying cumulative illuminance and cumulative amount of ultraviolet light in the LCD display.
The wide Luminosity range covers 0 to 130k lx and Low Light Resolution to 0.01 lx, with a UV range covering 0 to 30 mw/cm2. Internal accumulation of exposure is for both Light and UV. This compact, lightweight unit is approximately 2" X 3" and operates on one AA battery.
The TR-74Ui-H 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. This unit is compatible with any RTR-500 Series Wireless Data Collector and can be used for automatic downloading of logged data, real time monitoring and warning notifications by email or text to cell phones.
