## [Archive centres: climatic monitoring](/en-GB/solutions/archive-centres-climatic-monitoring) ![measure archive centre](/sites/default/files/entityone_paragraphs/images/SOLUTION_Intro_1000x1000_468_3.png) ## Optimum storage conditions Controlling the climatic conditions in archive rooms is essential for document preservation. Paper is sensitive to variations in temperature and humidity, so rigorous control of these parameters is an absolute must. With its various ranges of instruments, Sauermann offers measurement solutions to suit all requirements: from spot measurements using portable devices, to continuous monitoring, with measurement transfer and/or autonomous recording for data archiving. ## Parameters to be monitored - **Air flow** - **Hygrometry** - **Temperature** Storage conditions ## Storage conditions Document preservation requires the control of several parameters: temperature (from 16°C to 23°C), relative humidity (from 40% to 55%), and water weight (from 4.6 g/Kg to 9.7g/Kg). These conditions can only be maintained by effective air treatment. Temperature and hygrometry transmitters ensure continuous monitoring of these parameters, and can communicate with any type of monitoring system through analog or digital signals, or fully programmable electrical contacts.

Maintaining good air quality depends on air renewal, air diffusion and effective filtration. Sauermann offers a wide range of portable devices and accessories for use on all types of ventilation systems. Measurements of all air parameters (pressure, air velocity and flow rate, temperature, etc.) are easily carried out on grilles, diffusers or in ducts.

Sauermann solutions are able to provide alarms in the event of malfunctioning control mechanisms, and record the slightest variations. To ensure temperature and humidity stability in the building, Tracklog and Kistock solutions can track, alert and create a history of these measurement data with great reliability and precision. This data can be exported in the form of comprehensive reports to facilitate maintenance.
