Tinytag Ultra 2 data loggers are specially designed for indoor temperature and humidity monitoring. They are ideal for monitoring the efficiency of heating, ventilation and air conditioning in offices, workplaces and domestic properties. They are also widely used to help assess the performance of building materials such as insulation, and help evaluate ‘before and after’ conditions in environmental refit projects.
