Our objective is to assist curators in the ongoing battle for museum conservation and preservation of artifacts using environmental monitoring solutions which are already installed in many museums such as The Louvre & The Smithsonian.

Relative Humidity

Works of art including materials such as metal, dyes, and textiles 

Temperature and relative humidity (RH) are closely interrelated. Some independent effects of high RH include increased biological activity and acceleration of chemical deterioration processes. The Hanwell Pro USB and wireless data loggers are well established as the go-to instruments for museum conservation. The ML4106 and ML4114 wireless data loggers provide conservators with accurate tools to wirelessly monitor temperature and RH levels together. This recorded data can be used not only for alarms and historical data analysis but also to control humidifier or dehumidifier units as and when levels drift outside predetermined parameters, providing a complete solution to, temperature and RH management.

No bigger than a mobile phone, the HumBug smart logger is ideal for situations where logging may be temporary or for enclosing with a valuable shipment.

Light & UV

Works of art, furniture, photographs, textiles, books on display, in storage & in transit

In order to reduce and eliminate fading damage to the above materials the first step would be to monitor the light levels in areas where damage must be kept to a minimum.

Hanwell provides a range of instruments specifically designed for museums that enable curators and conservators to measure the levels of LUX and UV content of light to assist in identifying extreme exposure to artifacts on display or in storage.

Our ML4000LUX/UV series USB and wireless data loggers can record both light and/or UV levels within an area, assisting with museum conservation by recording correct levels of light.

Insect Pests

Furnishings, wooden materials, textiles

Most commonly seen insect pests found to be devastating to museum conservation of artifacts include: Anobium Puncatum, generally known as the common furniture beetle or ‘woodworm’, has been perceived to be the main cause of damage to timber in the UK over the last 100 years. Carpet Beetle Larvae chew holes in textiles.

In the past museums have relied on expensive toxic fumigation to control insect pests in and around artifacts. These methods kill insect pests but leave harmful gases or residues on the artifacts.

Following extensive research and development, our insect pest control system (AnoxiBug) uses a 100% reliable anoxia treatment (low oxygen method) that is cost-effective and can be used by museum staff.

Air Flow & Wind

Movement of air within museums and external weather conditions

Perhaps surprisingly, air can be drawn through a building at damaging rates, bringing with it pollutants that can affect the condition of monitored environments surrounding priceless artifacts.

Similarly, the external corrosion on buildings caused by the wind force (speed and direction) of rain, pollutants, and debris can have not only detrimental effects on the condition of the external building walls, but also potentially lead to internal damp. The RL2000, a wind speed and direction sensor can be used for museum conservation surrounding these issues which measure wind, speed, precipitation, barometric pressure, temperature, and humidity.

Monitoring parameters within critical areas like these can prevent further damage and assist with preservation processes.

Our Wireless products are British designed, tested and manufactured in England.
