Rotronic HL-1D & TL-1D data loggers are cost-effective instruments for remotely monitoring and recording humidity and/or temperature. Both loggers feature an
NTC sensor to measure temperature over a range of -20 to 70˚C with an accuracy of ±0.3°C. The HL-1D also includes a Rotronic HYGROMER IN-1 humidity sensor for
making measurements over a 0 to 100% RH range and ±3.0 %RH accuracy. The internal memory records 16,000 data points which can be logged in customer selected
intervals from 30 seconds to 24 hours.

Rotronic HL-1D & TL-1D data loggers are housed in an IP67 rated enclosure. The two-line LCD display shows real-time or stored values and makes setting up the
instrument a snap. The installed battery can last up to three years at a logging interval of 5 minutes.
