With the EDL-4S you can obtain Temperature, RH, CO2 and Vibration profiles in a compact low-cost 4-channel LCD data logger! Use either as a stand-alone device, or as a Wireless Data logger when connected to our separate WiFi Reader Station (coming soon). This device is perfect for mapping your warehouse, refrigerators or monitoring industrial machinery during shipment or stationary applications.

  • Temperature Sensor: RTD -200° C to +380° C, Accuracy ±0.3° C
  • Relative Humidity Sensor: Capacitive humidity readings 0% to 100% RH.
  • CO2 Sensor: Infrared 0 to 30,000 PPM accuracy ± 30 PPM ±5 %
  • Vibration sensor: 3-D Accelerometer with a sampling rate of 1 to 400 Hz.

Centralized Monitoring: The EDL-4S connects directly to the computer via a USB port for setup and downloading data. The device can also be remotely monitored via WiFi when attached to the separate WiFi Reader Station (coming soon). The Reader Station may be battery powered or AC powered, your choice.
Statistics and mathematical functions: In addition to temperature and humidity, this compact 4 channel LCD data logger calculates min/max. over alarm conditions and much more.

Alarms and battery backup: Alarm settings can be set up quickly in the MaxiThermal-X software based on temperature and RH. Likewise, alarm settings can be set up to trigger email notifications (coming soon). This device contains one AA lithium battery for ample power. The WiFi reader is powered by two rechargeable CR18650 batteries or with an AC adapter, which can power the logger and also charge the batteries in the reader..

Large, easy-to-read display: The EDL-4S is the ideal instrument for documenting, controlling, and managing critical environmental conditions graphically, statistically and in real time. View high/low data and all alarm conditions in real time on the LCD display.

MaxiThermal-X Software

MaxiThermal-X Software allows you to view up to 8 multiple traces at one time, enables you to transfer the recorded information in your loggers to your computer, and to view, print and generate a report of the measurement data. The graphic representations are a simple X – Y plot of time versus temperature with unlimited zoom, view temperature data points on the graph, view total elapsed time, or the exact time when it was recorded. The graph and all data points (date, time and temperature) can be printed, as well as the ability to add a user note to the file for including information pertinent to that particular plot.
Users have the ability to view numeric data in a screen window and Data can be Exported as a CSV file for use in other software. A Summary Information report showing the specific logger information, the Start and Stop Time, Duration of Recording, Measurement Interval, Highest, Lowest, Median and Average Temperatures as well as the High and Low Alarm information.

The data from the logger is easily downloaded to your PC via a standard USB 1.1 interface. MaxiThermal-X software is compatible with Windows XP, Vista, 7, 8 and 10.
