The HD33[L]MT.4 data logger with 4G/3G/GSM(2G)/GPRS module allows several physical quantities to be monitored remotely in a large variety of application fields. You can monitor, for example, temperature, humidity, atmospheric pressure, solar radiation, rainfall quantity, wind speed and direction, etc.
The data logger is equipped with:

• 4 analog independently configurable inputs (0…50 mV, -50…+50 mV, 0…1 V, 0…10 V, 0…20 mA or 4…20 mA, Pt100, Pt1000, thermocouple, potentiometer, pyrgeometer).
• 2 voltage-free counting contact inputs (e.g. a tipping bucket rain gauge and a cup anemometer can be connected).
• One RS485 port with Modbus-RTU protocol configurable as “Master” or “Slave”. Through an optional module, the data logger can be connected to an ETHERNET network and communicate with MODBUS TCP/IP protocol.
• One SDI-12 “Master” port compatible with version 1.3 of SDI-12 protocol.
• 2 voltage-free contact alarm outputs.

On request, input with M12 connector for relative humidity and temperature with NTC sensor combined probe or, alternatively, for temperature only probe with NTC sensor. If a relative humidity and temperature probe is connected, the dew point temperature is calculated.
