Rotronic HL-20D Data Logger
This data logger offers very high precision (0.8% RH and 0.2 °C) at a good price. A stand alone data logger can be used in a variety of locations to reveal environmental fluctuations in storage and display areas. The unit can be deployed not only to monitor general conditions, but can also be placed in more confined, temporary locations for example, inside storage systems. The high accuracy of this unit can be used to assist the conservator and curator to determine the efficiency of heating, ventilation and air conditioning systems in maintaining desired values.
Downloadable loggers can complement wireless systems, which are often placed in fixed locations to provide long term data. They can also be used in remote stores and historic buildings with minimal set up time. The internal memory can store up to 32,000 data points and battery life is up to 3 years. HW4-Lite programming and analysis software and data cable included.
