web data logger | HD 50...

general information:

The data loggers of the HD50 series allow indoor monitoring of various physical quantities. The data loggers are available for the monitoring of the following parameters: temperature, humidity, atmospheric pressure, carbon dioxide, illuminance.

Furthermore the models that measure relative humidity and temperature calculate absolute humidity, dew point, wet bulb temperature, mixing ratio, partial vapour pressure.

Models with 4 input channels with terminal header connections are available for the connection of standard analog sensors:

transducers with 0 to 20 or 4 to 20 mA current output and 0 to 50 mV, 0 to 1 V or 0 to 10 V voltage output
Pt100 / Pt1000 temperature sensors and type K, J, T, N, E thermocouples
sensors with potentiometric output

This allows the extension of the monitoring capability to countless other quantities, in addition to those listed above.

All the models can be supplied with or without LCD. The versions with LCD can be equipped with a custom LCD (option L: a quantity is displayed in the main row and the temperature, if available, is displayed in the secondary row) or with a graphic LCD (option G, a quantity is displayed in the main row and three quantities are displayed in the secondary rows).

Three LEDs on the front panel indicate the status of power supply, LAN/WLAN local network connection and alarm.
