• The dataloggers F412 and F812 have been designed for monitoring physical values where energy consumption and battery life is critical.
• Accurate monitoring of flow meters and water flow/consumption during short time intervals.
• Multiple point temperature monitoring.
• Small low cost monitoring stations for environmental parameters, meteorological data, water level, water flow and other parameters.
• Areas where vandalism or theft prevents using solar panels.
• Acquisition situations requiring flexibility and control of external devices or sensors by the datalogger.
• Applications requiring recurrent remote download by modem or radio-modem.
• The datalogger can be employed outdoor and indoor.
• The 12-bit resolution guarantees a resolution 16 times higher than 8-bit products commercialised by competition, making the use of Geosignal dataloggers ideal for detailed acquisition.

• USB / RS232 cables for PC connection.
• Water Flow Meter
• Unit Meteo 4 for micro clima monitoring.
• External connection board for easy wiring.
• Temperature probes (-30 +80 °C)
• Relative Humidity Probes (0 100%)
• Position sensor
• Custom
