EL-SIE-2+
High Accuracy Temperature and Humidity
USB Data Logger, EasyLog Cloud Compable
Monitor the environment you live and work in with the EasyLog EL-SIE-2+. Conguraon is simple, with no soware to install
on your PC or Mac – just connect the logger with a USB cable, and use your standard web browser to congure the device for
logging. You don’t even need internet access to set up and use the EL-SIE-2+, it really couldn’t be easier.
The logging interval can be set between 10 seconds and 24 hours, with immediate, delayed, triggered or push-to-start logging.
Alarms are fully user congurable, with funconality including cumulave alarms, pre-alarms, a delay before alarm triggering,
and an alarm hold opon, which connues showing the alarm condion even if the reading returns to an acceptable level.
The display shows current, maximum and minimum readings, and three coloured LEDs indicate device status at a glance.
Once logging is complete, re-connect to your computer and use your browser to view, analyse and save your data. You can also
choose to upload your data to an Easy Log Cloud account, making the data accessible online for powerful graphing, analysis and
report generaon.
Typical baery life is over 1 year using standard AAA alkaline baeries, and a wall mounng bracket is supplied with the device.

EL-SIE-2+
High Accuracy Temperature and Humidity
USB Data Logger, EasyLog Cloud Compable
NO SOFTWARE TO INSTALL
All the soware needed to congure your EL-SIE-2+, and view and analyse the data it logs, is contained within the product itself. Just
connect the logger to your PC or Mac with a USB cable, open any web browser and in the address bar type “hp://EasyLog.local”. No
internet connecon is needed, and you can save this address in your bookmarks or favourites as normal.
The interface is easy to use and allows the following parameters to be congured:
• Logger and channel names
• Measurement units
• Logging rate and start mode
• Up to 16 separate alarms (high/low/pre-alarm/cumulave)
with thresholds, delay and hold
• Display and LED indicator modes
Once the logger is running, you can plug it back
into your computer and see the latest data, device
status and the event log. You can also chose to
stop the logger and change the conguraon, or
just let it connue logging.
EASYLOG CLOUD DATA STORAGE
Store your data securely, and make it available from
any internet-connected PC or mobile device, with
EasyLog Cloud. The EL-SIE-2+ can upload logged data
to the Cloud from your PC or Mac, making sharing
and analysis easier than ever. For more informaon

SENSOR ACCURACY AND INFORMATION
Typical and maximal tolerance for the temperature sensor in °C:
Operang Condions
The performance of the humidity sensor can be aected by long-term exposure to operang condions at the extents of the logger’s
range. The sensor shows best performance when operated within the recommended normal temperature and humidity range of 5 to 55°C
and 20 to 80%RH, respecvely. Long-term exposure to condions outside the normal range, especially at high humidity, may temporarily
oset the RH signal (e.g. +3%RH aer 60h kept at >80%RH). Aer returning into the normal temperature and humidity range the sensor
will slowly come back within the calibraon state by itself. Prolonged exposure to extreme condions may also accelerate ageing.
Typical tolerance of RH over Temperature:

High Accuracy Temperature and Humidity
USB Data Logger, EasyLog Cloud Compable
When tracking changes in ambient condions, the response me of the humidity sensor in your data logger is approximately 20 minutes
to reach 90% of the reading. However, if you are measuring step changes in humidity (for example if calibrang the product) it is advised
that you leave the unit for up to four hours to ensure that it has enough me to sele at the new level.
It is worth remembering that the value of relave humidity is of course sensive to temperature variaon. As an example, at a relave
humidity of ~90%RH at ambient temperature, a variaon in temperature of 1°C will result in a change of up to -5%RH. Therefore when
comparing mulple devices or calibrang them, any temperature variaons must be considered.
The humidity measuring element in the humidity data loggers can be contaminated through exposure to a variety of compounds. These
products should not be kept in proximity to volale chemicals such as solvents and other organic compounds. Generally speaking, if a
material or compound emits a strong odour you should not keep your humidity data logger in close proximity to it. If you would like more
informaon, please contact your local Lascar Electronics oce.
High levels of pollutants may cause permanent damage to the internal sensor.
BATTERY INFORMATION
We recommend that you replace the baeries annually, or prior to logging crical data. Use only AAA 1.5V alkaline baeries. Before
replacing the baeries, disconnect the logger from your computer.
The logger does not lose its stored data readings when the baeries are discharged or replaced. However, the logging process will stop
and will not resume unl the baeries are replaced and the logger is connected to your computer and the logger is started.
Note that while the logger is plugged into a computer it draws power from the USB port instead of the baeries, which can raise the
temperature of the logger slightly. It will return to normal shortly aer disconnecon.
