Littlemore Scientific

At Littlemore Scientific (ELSEC), we specialize in designing and manufacturing environmental monitoring equipment trusted by museums, galleries, archives, and conservation professionals around the world. For more than 70 years, our mission has been to combine engineering innovation with scientific precision, delivering tools that protect the integrity of priceless collections and cultural treasures.

Our story began in the 1950s in Dorset, England, when we first created scientific instruments for research at Oxford University. Since then, ELSEC has evolved into a leader in museum preservation technology. Over the decades, we have designed and produced a wide variety of instruments and machines, from screen-printing equipment and magnetic observatory components to medical aids and archaeological dating devices. That spirit of versatility and problem-solving continues to define our company today.

Now, our focus is clear: producing the most reliable conservation monitoring tools for institutions safeguarding art, artifacts, manuscripts, and historic objects. Our product range includes:

• UV monitors for detecting harmful ultraviolet exposure
• Lux meters and light monitors to measure visible light intensity
• Humidity meters and temperature sensors for climate control
• Environmental dataloggers for continuous recording and reporting
• Multi-function handheld devices for on-the-go monitoring

One of our earliest breakthroughs was the Type 762 monitor, developed in the 1970s to help conservators control light and humidity. That innovation paved the way for newer generations of monitoring systems—the 763, 764, and now the 765 Environmental Monitor—each advancing in accuracy, durability, and ease of use.

Our flagship product, the Model 765 Handheld Environment Monitor, demonstrates ELSEC’s commitment to practical, conservation-focused technology. This portable device measures visible light, UV light, relative humidity, and temperature with outstanding precision. Its rugged metal design, rechargeable batteries, and OLED display with automatic brightness adjustment make it a dependable tool for curators and conservators who need reliable readings in real time.

All ELSEC instruments are designed, engineered, and assembled at our facilities in Gutchpool Farm, Gillingham, Dorset. By keeping production in-house, we maintain strict control over quality, calibration, and performance. Each device undergoes rigorous testing to ensure it meets the demands of environments where the stakes are high: national museums, historic libraries, cultural heritage archives, and private collections.

As a medium-sized company with a global reputation, ELSEC combines the flexibility of a hands-on manufacturer with the reach of an international supplier. Our network of distributors and representatives allows us to serve clients worldwide, offering not only instruments but also expert guidance, servicing, and calibration support. We pride ourselves on delivering personalized solutions tailored to the challenges faced by preservation professionals.

Clients choose ELSEC not only for the proven reliability of our equipment but also for the trust we build through ongoing support. Whether recommending the right monitoring system, providing detailed technical advice, or developing custom solutions, we act as partners in the mission of safeguarding cultural heritage.

Looking to the future, ELSEC is committed to advancing the field of environmental monitoring for museums and galleries. We are investing in new technologies that deliver greater accuracy, sustainability, and ease of use. Our goal is to continue equipping conservators with tools that protect collections from the damaging effects of light, UV radiation, temperature fluctuations, and humidity.

From our origins in scientific research to our role today as a trusted supplier of museum conservation equipment, ELSEC remains driven by a single purpose: helping institutions around the world preserve history for generations to come.
