Museums & Exhibitions

Whilst swings in temperature and humidity in normal environments may not be significant, in a museum they can be catastrophic. Exposure to extremes of heat, cold, dryness or humidity can cause textiles, canvas, wood and other materials to quickly deteriorate. Factor in a display case and there may be multiple environments in just one room. Maintaining those same environmental conditions is also essential during the transportation and storage of exhibits and artefacts. 


Remote Monitoring

Remotely monitor your environments, protect your exhibits and stored collections and get early warning of potentially damaging conditions with instant alarm notifications using our WiFi connected 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 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.

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.

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. 

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.

Lascar Products in the Field

Don't take our word for it. Read how some of our customers have been using Lascar data loggers in the field to track temperature and humidity in public galleries, individual display cases and archive storage areas. From the Asia Society's use of our WiFi loggers in protecting their collection of public and archived Asian artefacts, to the Bury Art Gallery's use of loggers in tracking individual display cases, the monitoring of the largest postcard collection in the world and the monitoring of Roman artefacts at the Fishbourne Roman Palace in Chichester, England.

What Do The Experts Say?

"An unstable level of humidity can lead to hygroscopic materials to swell (in high humidity) and contract (in low humidity). This swelling and contraction of the material causes stress on the connecting fibres, gradually weakening them causing embrittlement, flaking oil paintings are a good example of expansion and then subsequent contraction. Some materials may show some efflorescence of salts as they crystallise after being dissolved. Fluctuations shouldn’t be more than ±3% relative humidity within a 24 hour period.

The ideal temperature for preservation of archival documents is between 16°C to 19°C. Increases in temperature can also have an adverse effect on collections. It is estimated that for every 10°C increase in temperature, chemical reactions in paper double. Heat also causes expansion and contraction which, regardless of relative humidity level, can lead to damage to collections."
