Overview

The A753 GSM / GPRS Telemetry datalogger is a comprehensive datalogger with in-built power provision for attached sensors. is a complete overhaul of its successful predecessor the A733 GPRS and can be used for a huge variety of applications.

Water quality sondes such as the Manta2 have digital SDI-12 interfaces to increase compatibiliy and accuracy. A753 allows the operation of up to 40 SDI-12 or modbus (requires additional low cost option adapter), 12 0-2,5V inputs with 16-bit resolution for accurate analog sensors along with 4 digital pulse inputs and 4 digital outputs for switching processes on/off such as valves or pumps.

The A753 telemetry datalogger is without doubt the most cost-effective and comprehensive datalogger of its kind. Whether you wish to connect to water meters, turbidity sensors, water quality sondes, weather stations, groundwater sensors, 30 level sensors, turn pumps on/off, the A753 telemetry datalogger is without doubt the only instrument that can do the job.
