HD206.../HD226... and HD207.../HD227... series Temperature Relative Humidity data loggers are low-cost, rugged instruments, for a long-term reliable monitoring of temperature and temperature,
relative humidity measurements. 
They are available in different versions: with or without LCD display, with temperature sensor either inside or outside the instrument housing, or with cable connection

Excellent protection against atmospheric agents.
Temperature and relative humidity high accuracy all over the range.

Resolution: 0.1°C, 0.1% RH.

Sampling freely selectable by the user.
Manual control of acquisition start and stop either through a pushbutton or a clock.

Fast download of stored data.
240.000 data capacity on a single channel and 80.000 data capacity on three simultaneous channels.

The analysis of acquired data is made using DeltaLog2 software for Windows. 
The datalogger functions of Start, Stop, Configuration, Data Download and Setting of storage interval are selectable either from keyboard or from a computer. Through a computer, you can define a password to enable the access to configuration data.
