3. System Overview

The ECOLOG-PRO xG autonomous Mobile-IoT sensors with replaceable battery, communicate via public telecom network. The data logger family described in this document are used for stationary temperature and humidity monitoring. The measured values are transmitted via the cellular network to a monitoring software (elproCLOUD) which stores and analyzes the data, provides alerts if alarm limits are violated, and generates reports. The system provides superior visibility and transparency in meeting GxP requirements. The sensor-based monitoring software is easily accessible via a web browser and is also used to configure the devices.

Following pages cover key functionality of the wireless data logger (ECOLOG-PRO 1TGi / 1THGi / 1TGe). For more detailed software instructions, please visit our online knowledge base:

4. Functionality and Modes

Unless otherwise noted the following information applies equally to all three ECOLOG-PRO xG models. After configuration of the data logger measured values for temperature and relative humidity (ECOLOG-PRO 1THGi only) are recorded, stored and evaluated with regard to the defined alarm criteria. The display shows the current mode.

4.3.1 Shelflife

When delivered, the device is not powered, but with insulation strips on the battery contacts.

• After removing the isolation strip / inserting the batteries, the instrument asks if the batteries are new (NEW.BAT: Y/N). Confirm by pressing the Info/Menu button for more than 2 seconds.

• Then, the instrument goes directly to CONFIG state. Through the RADIO.OFF menu the device can enter SHELFLIFE state.

4.3.2 Configuration & Start

• By pressing the pairing button (>2 seconds) the device is pulling a configuration of the cloud, and the Run icon on the display indicates a successful start.

4.3.3 Pause (Alarming off)

Via the elproCLOUD software, the alarming of the device can be turned off and on again in order to pause alarming for a specific timeframe.

4.4 Menu

The ECOLOG-PRO xG family feature a menu to operate the device:

• To enter the menu, press the Info/Menu button for at least two seconds

• To switch between the menu options, press briefly the Info/Menu button

• To select a menu item, press the Info/Menu button for at least two seconds. To confirm, a selected menu item blinks once.

• To leave the menu

  • wait for 5 seconds

  • or press the left button

  • or select the last menu item EXIT

All menu items and their availability are described in the table below (no menu available in SHELFLIFE mode)

6. Accessories

6.1 Bracket

ELPRO offers an optional bracket (BRA_LIBERO Gx, part number 802375) for mounting of ECOLOG-PRO xG data loggers if required, i.e. to containers for cryogenic applications. The bracket is made of solid ABS plastic to protect the data logger but not influence the communication. It consists of an upper and a lower part. The ECOLOG-PRO xG is inserted into the lower holder from above.

6.2 External Pt100 Probes for ECOLOG-PRO 1TGe

ECOLOG-PRO 1TGe can be used for different applications, depending on the sensor element. ELPRO offers standard probes for three main applications:

• Cryogenic storage

• Dry ice storage

• Freezer (-25 °C ... -15 °C, typical) / fridge (+2 °C ... +8 °C) / ambient (+15 °C … +25 °C) storage

6.2.1 Cryogenic storage

For cryogenic applications the ECOLOG-PRO 1TGe is usually mounted directly to the container or the container lid, using the optionally available bracket with the sensor leading into the tank. ELPRO offers an easy, turnkey service for mounting the assembly and calibration.

ELPRO offers three Pt100 standard probes for cryogenic applications with M8 connector in different lengths:
