Facilities Management

To determine the efficiency of heating, ventilation and air conditioning systems, data loggers can be used to monitor temperature, humidity, pressure and carbon monoxide, ensuring systems are working correctly and identifying any possible system issues. Monitoring environments also play an important part in ensuring optimum levels of comfort, air quality, and health and safety in a variety of applications. Lascar's comprehensive range of data loggers provide cost-effective, professional and simple solutions from standalone USB devices to WiFi-based data loggers monitoring and displaying data via any internet-enabled device.



Remote Monitoring

Remotely monitor your environments and get early warning of poor conditions with instant alarm notifications using our temperature WiFi and temperature & humidity WiFi devices. Lascar's WiFi sensors are easy to set-up using a smartphone App. Simply log on to your EasyLog Cloud account from any internet enabled device to access secure real-time and historical data, remotely change individual sensor settings and create individual locations for one or multiple devices.

Stand Alone Data Logging

Lascar’s EL-USB range includes discrete, battery powered temperature and temperature & humidity data loggers that measure and store temperature and humidity readings on-board until data is downloaded via USB. Simple to set-up, just plug any of these devices into the computer USB port and, using Lascar’s FREE software, name the device, choose a sampling rate, select high and low alarms if required and a logging start time. Loggers stores up to 32,000 readings, includes displays showing max, min and last logged values as well as flashing alarm and low battery LEDs.

Our next-generation EL-SIE range measure ambient temperature, humidity and pressure and can store over 1 million readings. They feature a number of powerful, user-configurable alarms and include a display and LEDs to indicate device status at a glance. Advanced onboard software means there is nothing to install on your PC or Mac – simply connect the logger with a USB cable and use your web browser to configure the device and view, analyse and download your data. 

The EL-GFX family boasts over 250,000 readings per parameter, an on-screen display showing max, min and last logged values as well as an on-board graph of the data collected. Buttons allow the user to start, stop and restart the logger in the field and alarm breaches can be registered with both LED and audible alarms. 

Pre-Calibrated Probes

Need to re-calibrate your sensors annually? Leave your EL-MOTE-TH sensor in the field and simply purchase a new pre-calibrated probe. No loaner stock. No disruption. Simply replace the probe and keep logging.
