Wireless logger: log-EZ (RTR-322) for temperature and humidity

Connection and operation are not further complicated: After switching on, the small lightweight (62g) records temperature (0 ... 50°C) and humidity (15 ... 95% RH) every 10 minutes. It can store up to 1440 records internally, which is enough for about 10 days. After that, the oldest data is overwritten cyclically in each case.

Communication with the PC is realized via a proprietary radio link. A radio dongle RTR-300 is connected to the USB port of the computer for this purpose. The range here is initially 50m (unbuilt), but each additional wireless logger also acts as a repeater and extends the range by another 50m each. Up to 16 log-EZ can be inserted into such a radio logger network.

Unbeatable is the price for such a logger kit: For about 160€ you get the basic equipment "RTR-322Kit" with radio logger and dongle. Additional loggers RTR-322 cost about 110€ each.

Included in the price is the display and evaluation software "log-EZ for Windows".
