Introducing the RS PRO RS-91 Mini Data Logger. This compact device has been designed with a high accuracy temperature and humidity sensor that is ideal for monitoring and collecting data from environmental temperatures and humidity. This RS PRO data logger records temperature, humidity, dew point and more, and can be used to record and detect changes in the ambient temperature and humidity in real time. This high-quality data logger unit is suitable for use in a wide variety of applications for easy and convenient data recording and collection.

• This RS PRO data logger has been designed for high accuracy measurement and fast response, that measures and displays changes in the ambient temperature and humidity rapidly
• As well as measuring ambient temperature and relative humidity, this unit also measures dry bulb temperature, wet bulb temperature and dew point temperature
• The data collected can easily be transferred via the Bluetooth feature that can be connected to the user’s smartphone or other Bluetooth enabled device
• The large, high-resolution LCD screen is ideal for showing the logging and measurement information more easily and uses touch screen operation with an easy zoom in/zoom out function

• The data logger also features an alarm display if user-defined maximum or minimum values are exceeded, with a user-selectable option for °C/ °F temperature display
• The unit contains a 9V battery and an auto power off function to extend battery life when left idle, as well as a low battery warning when the battery drops below a certain voltage

A data logger is a key piece of equipment for collecting data. It is often used instead of using valuable resources or man-power to manually log and record data and they can be placed in environments that are not always suitable for humans over long periods of time, for example when monitoring refrigeration or chilling units. Data loggers are incredibly useful devices that can offer use in a wide range of applications like:
• Environmental and weather monitoring
• Agricultural and livestock
• Food and drink production
• Building and site monitoring
• HVAC
• Health care
• Accommodation
• Offices
