Humidity, Temperature and Dew Point Data Logger with LCD

This standalone data logger measures and stores up to 16,379 relative humidity and 16,379 temperature readings over 0 to 100%RH and -35 to +80°C (-31 to +176°F) measurement ranges. The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the supplied software. Relative humidity, temperature and dew point (the temperature at which water vapour present in the air begins to condense) data can then be graphed, printed and exported to other applications.

The high contrast LCD can show a variety of temperature and humidity information. At the touch of a button, the user can cycle between the current temperature and humidity, along with the maximum and minimum stored values for temperature and humidity. The data logger is supplied complete with a long-life lithium battery, which can typically allow logging for up to 1 year. The data logger is protected against moisture to IP67 when the protective cap is correctly fitted.

Display and Status Functions

The EL-USB-2-LCD+ features a high contrast LCD and two bi-colour LEDs. The LCD shows logged temperature and humidity values using seven segment numbers, along with annunicators. The LCD can also show information regarding the logging status.

The LCD shows six different recorded readings, which can be cycled through using the built-in push button. The most recent logged value, maximum logged value and minimum logged value can be displayed seperately for humidity and temperature. In addition, logging and alarm status is shown using two high intensity LEDs.

LED Flashing Modes

EL-USB-2-LCD+ features 2 bi-colour LEDs; one LEd reprents temperature measurement, the other represents RH. Each is clearly marked on the logger. To save power, the status indication alternates between the two channels every 10 seconds. First you will see the status of the temperature logging and 10 seconds later you will see the status of the RH logging and so on.

* This specifies the overall error in the logged readings, for relative humidity measurements between 20 and 80%RH.
** This specified the overall error in the calculated dew point, for relative humidity measurements between 40 and 100%RH at 25°C.
*** Depending on sample rate, ambient temperature and use of alarms LEDs.

EasyLog Software

The core of Lascar's data logging solution is the free software supplied with each data logger. Using a wizard format to guide the user through setup of the data logger and subsequent download of collected data, the software puts the 'easy' into EasyLog.

Features

• Collects and stores data from at least 500 data loggers
• View downloaded data with general trend and summary screens
• Allows full or quick set-up of compatible EasyLog USB data loggers
• Touch screen interface for navigation of menus
• 2.8” TFT display
• Stored data can be transferred to a PC/Mac via micro USB cable
• Use Lascar’s EasyLog USB software on a PC to graph data and export to Excel
• Integral rechargeable lithium battery provides up to 8 hours use (nominal)

The EL-DataPad allows users of Lascar’s EL-USB data loggers to configure their units and download data and view logging results on-thespot rather than removing the logger from the environment being measured and taking it to their PC. This allows continual logging with shorter breaks in data collection, less travel for the user, on-site data collection in graph, legend and summary format and the ability for users to reconfigure loggers in ‘the field’.

The logger is connected to the EL-DataPad via a standard USB port at the top of the viewer. Once connected, the user is guided through a simple touchscreen menu with options to Set-Up Logger, Stop Logger & Download and View Data. On-screen instructions follow the same structure as Lascar’s EL-USB-WIN software for PC currently provided with each data logger.

Data from up to 100 loggers can be viewed on the EL-DataPad, with data from a further 400 units stored on the unit at any one time. Data can be transferred to a PC or Mac using a micro USB cable supplied with the unit. Once uploaded, data is saved in comma separated variable (csv) format, making it suitable for import into spreadsheet packages such as Microsoft Excel or graphed on a PC using Lascar’s EL-WIN-USB software .

The EL-DataPad is compatible with the following EL-USB data loggers: EL-USB-1, EL-USB-1-LCD, EL-USB-1-PRO, EL-USB-2, EL-USB-2+, EL-USB-2-LCD, EL-USB-2-LCD+, EL-USB-TC, EL-USB-TC-LCD, EL-USB-LITE.
