Transmitter Measures Four Parameters
TandD has released the high-precision TR-74Ui-H four-parameter data logger, which can achieve a temperature measurement accuracy of ±0.3 degrees Celsius (between 10 to 40 degrees Celsius) with an overall range of 30 below zero to 80 degrees Celsius. The humidity measurement accuracy is ±2.5% (at 25 degrees Celsius, 10 to 85% RH) with an overall range of 0 to 99% RH.
The TR-74Ui-H Illuminance UV Recorder can simultaneously measure and record four parameters: Illuminance, Ultraviolet Light (UV), Temperature and Humidity. In addition to those parameters, the TR-74Ui-H can also display cumulative illuminance and cumulative amount of ultraviolet light on its LCD. The wide luminosity range covers 0 to 130k lx and low-light resolution to 0.01 lx.
The TR-74Ui-H has a large data capacity which can store up to 8,000 readings times four channels for a total of 32,000 readings in One-Time or Endless recording mode. Simply by connecting to a computer via a USB port, the recorded data can be quickly downloaded with the easy-to-use software.
