Temperature & Humidity Data Logger

temperature-and-humidity-data-loggerThe humidity data logger is often a combined instrument along with a temperature data logger. It measures the amount of water vapour in the air and maintains a record of the same for later analysis. The reading is measured in Relative humidity as a percentage. Certain instruments can also measure absolute humidity in terms of grams per cubic meter. Just as temperature variations can affect the quality and safety of manufacturing processes, uncontrolled humidity levels too can create numerous problems and issues. This is why most customers buying a temperature data logger prefer a device that can simultaneously function as a humidity data logger as well. The long term recording of humidity and temperature conditions is significant in the pharmaceutical business, creation forms, stockpiling, test offices and numerous different territories. Once logged, the temperature and humidity data can be assessed measurably. This gives significant data on conditions that can have an effect on individuals and item quality.
There are different types of humidity data logger devices available in the market. Some of them include:

Temperature & humidity recorders by application

  1. Standalone Temperature & Humidity Data Loggers & recorders

    This data logger device is a portable standalone device with its own internal power source. The customer can simply place this data logger in a room for continuous recording. These are the most common types of humidity recorders. Most common applications include recording the temperature and humidity of medicines, vaccines, fruits, vegetables, frozen food, processed food, chocolates etc.temperature-humidity-data-logger-vackerglobal

  2. Panel-Mounted Humidity Data Logger

    This device can be used to set up a comprehensive safety control unit that indicates a wide of internal data related to numerous parameters like temperature and humidity at a single glance. Such humidity data logger devices come with different types of sensors with varying sensitivity parameters. You just need to choose the device that suits your requirements best.

  3. Multi-Functional Humidity Data Recorders

    Measuring multiple parameters like temperature, humidity, CO2 levels, particulate matter levels etc. is possible in a single device. It can simplify the process of monitoring important data within a clean room environment or within a manufacturing plant where production must be done under controlled conditions.

    With the world moving towards the Internet of Things, which refers to an automatic transmission of data between machines, the humidity data logger in a room or manufacturing plant may automatically transmit data to the internal climate control mechanism. This means the humidity data logger will automatically provide data for adjustment of temperature and humidity controls in the room for a comfortable and functional internal environment at all times.
    A rugged humidity data logger designed to operate in harsh and unforgiving conditions can help scientists collect useful and reliable data about the climate of a city or region for more accurate calculations and conclusions.
