This new, high-precision wireless 4 channel light logger achieves a temperature measurement accuracy of ±0.3°C (between 10 to 40°C) with an overall range of -30 to 80°C while the humidity measurement accuracy is ±2.5% (at 25°C, 10 to 85% RH) with an overall range of 0 to 99% RH.
Other features include a TR-574-H illuminance UV recorder that 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 and the UV range covers 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 8000 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.
