  • Page 4: Introduction

    1 INTRODUCTION HD32MT.3 data logger is able to acquire and store measured data from a series of environ- mental sensors connected to its inputs. The data logger has an SDI-12 port, to which you can connect up to four sensors, and an RS485 port with Modbus-RTU protocol for connecting Delta OHM sensors, such as: HD52.3D…...
  • Page 5 The connection to a PC through the USB port of the data logger does not require the installation of any USB driver: when connecting the instrument to a PC, the Windows® operating system auto- matically recognizes the instrument as an HID device (Human Interface Device) and uses the driv- ers already present in the operating system. HD32MT.3 V1.2...
  • Page 6 The data loggers equipped with the optional GSM/UMTS module can automatically send, at regular intervals, the data to the Delta OHM portal “www.deltaohm.cloud”. This allows you to view the data from anywhere in the world, even by using mobile devices (tablet, smartphone, notebook), simply having an Internet connection and using a web browser.
