Temperature & Humidity

Collections containing materials such as paper, metal, and textiles

In high relative humidity (RH) conditions insects and molds thrive and reproduce readily, metals corrode, dyes and textiles fade and deteriorate more quickly, organic materials such as wood and leather swell or change shape, and gelatine emulsions and adhesives become sticky.

Hanwell Pro’s USB and wireless data loggers are well established for monitoring RH for private collections such as these. The ML4106 and ML4114 wireless data loggers provide conservators with accurate tools to wirelessly monitor temperature and RH levels together.

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

Collections containing materials such as paper, photographs, paintings and textiles

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

Our light measurement equipment assists to prevent light damage caused by fading in private and corporate collections.

The ML4000LUX/UV series of USB and wireless data loggers can record both light and/or UV levels within an area, helping collection owners to ensure the correct levels of light are being monitored and maintained. The use of wireless sensors over USB data loggers provide users with immediate alarm notification of unacceptable conditions allowing a preventative action to be taken.

Insect Pests

Organic materials such as paper, textiles, glue, and gum of bookbinding

A common problem within collections comes from irreversible damage to wooden frames, canvas and other textiles mostly caused by insect pests. Termites, silverfish, clothes moth are most commonly found to be responsible for feeding on organic materials within valuable private collections.

The Hanwell Pro AnoxiBug system is a cost-effective anoxia treatment that can be used in-house with ease when an infestation occurs. The infested items are placed in an aluminum packet with an oxygen indicator. When the bag has been sealed the oxygen levels are lowered to such a point that all insects perish. The bag (containing artwork) and environmental indicator can either be stored at this point or reused for other items.
