As mentioned, this article will focus one of the most popular temperature logger from Lascar: The EL-USB-1 datalogger. Lascar is based in the UK and is specialised in USB dataloggers for a number of uses, such as datalogging of temperatures, humidity, air quality, voltage etc.

The comparison will focus on relevant criteria. These are: Calibration, alarm functions, setup, support, data transfer, measuring range and settings. As this article will show, there are similarities but also a number of of key areas where there are major differences.

·       It is possible to monitor data easily from an app or web browser with Eupry.

·       Eupry provides free annual calibration by providing an instant device replacement.

·       Eupry’s subscription plans provide an ongoing support.

·       Eupry’s wireless data logger automatically sends data to the cloud.

·       With Eupry, a single click can change the settings on all your data loggers at once.

·       If you have a small setup and it is not important that temperatures are sometimes exceeded, you should go for a USB data logger.



Calibration of data loggers

Calibration is about ensuring that measurements are performed correctly so you can rely on them. With a well-executed calibration, it is ensured that your data loggers measure the same values ​​as all other data loggers. Read more about the importance of calibration here.

The majority of data loggers on the market do not include a calibration service. This means that customers have to use their supplier or a third party to ensure that their devices are calibrated each year. In cases where users forget or simply miss the annual calibration deadline, there is a risk of reduction in accuracy and reliability. For companies working within food or pharmaceutical industries this could potentially lead to non-compliances with GDP (Good Distribution Practices).

A standard calibration of a USB datalogger will typically cost € 70-90 per unit. The process can take up to 4-8 days during which customers have to arrange alternative solutions. E.g. by having spare data loggers in place.

Eupry relies on a subscription-based concept where Eupry once a year replace data loggers with new, calibrated loggers and take the previous loggers back to the calibration. This annual service is included in the premium subscription fee. In the standard subscription, this service is limited to three data loggers per year. 

The data loggers are calibrated calibration laboratory using systematic and validated procedures. The laboratory is accredited according to the internationally recognised ISO / IEC 17025 standard for calibration laboratories. This accreditation is recognised by almost all European countries. Regular inspections performed by the approved accreditation body, DANAK guarantees that Eupry offers highly accurate calibrations. Read more about how Eupry calibrate here.

Temperature monitoring doesn’t need to be costly or time consuming!

Alarm functions

The Lascar EL-USB-1 data logger does not come with any remote alarm functions or any other types of alarms.

Eupry’s WiFi data loggers send an alarm via SMS and/or email when temperatures are outside the allowed limits. Users can thereby react in real time instead of discovering too late that the goods have been ruined.


Install a Program on a Computer vs Access a Web App from anywhere

The Lascar EL-USB-1 data logger comes with a program that must be installed on a computer to be able to change configuration and access data. With Eupry, you open a browser and sign into an account when you want to monitor data. For some organisations, especially large ones, it is a time-consuming task to get new software approved. Opening an internet browser and a homepage is always fast and always a possibility wherever you are. More importantly it won’t require permission from the IT department.


Measuring range

Both systems guarantees a +/- 0.5°C accuracy and both will often be even more accurate. The standard measuring range of the Lascar EL-USB-1 data logger is between -35°C to +80°C.

The standard range of Eupry’s WiFi data loggers are -50 to +50 and -90°C to +150°C with probes installed. You will therefore be able to accurately handle everything from ultra-low temperature freezers, to high temperature incubators with Eupry’s WiFi data loggers.


Self-service and Manuals vs Support Staff

The Lascar EL-USB-1 data logger comes with a manual to assist with setting up the system. Eupry has a dedicated online support centre as well as fully trained staff available to call or email whenever you need help. If allowed by the user, Eupry’s staff can access your system and assist with setting up and configuring the data loggers as well.


USB Data Transfer vs WiFi Connection

The memory of the Lascar EL-USB-1 data logger needs to be emptied approximately every two weeks. Otherwise data will not be recorded and consequently lost.

Eupry’s wireless data logger automatically sends all data to our servers. Therefore you don’t need to worry about losing any data. Furthermore you don’t have to spend time on emptying the memory every few weeks. If the WiFi datalogger is offline, the datalogger has internal memory that works for up to 30 days. When the connection is reestablished, data will be synced.


Manual Setup vs Automatic Settings

If you are using several dataloggers from Lascar, you need to set aside some time to perform custom configurations every time data needs to be exported – especially during deployment. With Eupry however, a single click can change the settings on all data loggers at once. This is possible because the settings are changed directly from Eupry’s web interface.


Bottom Line

Both Lascar’s EL-USB-1 data logger and Eupry’s WiFi data loggers are very good at their main tasks: Measuring temperatures.

Eupry offers a combined service that focus on making temperature monitoring as easy as possible for the customers. Initially, the Lascar’s EL-USB-1 data logger may seem like the cheapest option but the cost for annual calibration, man-hours etc. can add up and actually make it the most costly option.


We aim to be as objective as we can in this article to give a fair comparison between Lascar EL-USB-1 Data Logger and Eupry Premium.
