•Ethernet & WiFi Temperature Data Loggers

edl 8 channel ethernet and wifi data logger for temperature, humidity and carbon dioxide (CO2)

EDL-8 WiFi - New Wireless and Network enabled 8 Channel Data Logger.

The most accurate multi-sensor graphical data logger on the market. The EDL-8 WiFi has eight channels with three types of NIST traceable interchangeable sensors. Each sensor is calibrated for both temperature and humidity by the sensor manufacturer.

  • Temperature Sensor: RTD -200°C to +380°C, accuracy ±0.2°C at center.
  • Relative Humidity Sensor: Capacitive humidity readings 0% RH to 100% RH.
  • CO2 Sensor: Designed to measure percentage of carbon dioxide up to 30%. It is useful for biological or scientific applications where high levels of CO2 must be maintained in an enclosed apparatus.
  • Vibration: COMING SOON.

Ethernet and WiFi capability

EDL-8 WiFi can be monitored remotely via Ethernet connectivity or via a WiFi network. The device also connects directly to the computer via a USB port.

Statistics and mathematical functions

In addition to temperature, humidity, pH and CO2 levels, the compact state-of-the-art device calculates minimum- maximum-time over alarm conditions and much more. Simply push the mode button and the channel selection.

Alarms and battery backup

Alarm settings can be set up quickly in the MaxiThermal WiFi software based on temperature, RH, and level of CO2. Alarms are both visual flashing display and red flashing LED. Likewise, alarm settings can be set up to trigger email notifications. In the event of a power outage, the internal lithium ion battery (when fully charged and when the backlight is not on) will continue to record data for approximately 24 hours.

Large, easy-to-read display

Now view data remotely for all your locations from your desk. The EDL-8 WiFi is the ideal instrument for documenting, controlling, and managing critical environmental conditions graphically, statistically and in real time. Up to sixteen different display set-ups can be stored and recalled at the touch of a singe button. You can easily modify this to get exactly what you want. View high/ low data and all alarm conditions in real time from the Dashboard for all your remote locations.
