  • CO2 is present in ambient air at a background concentration of around 400 ppm (0.04%). In any enclosed environment the concentration will increase in excess of 1000ppm (0.1%) if the room is poorly ventilated well.Carbon dioxide (CO2) is not harmful to human body when it is low, but when the concentration reaches 1500-2000ppm, people will feel wheezing, headache, and dizziness.And higher levels are serious harmful to health.
    • 🔔 Fast Response and High Sensitivity The CO2 detector uses high-precision NDIR sensor to accurately monitor carbon dioxide concentration, and provide you the CO2 risk warning effectively.
    • 🔔 Large Digital Display and Easy Read 2.8 inch TFT full colour screen clearly displays the real-time CO2 concentration, temperature, and humidity from the surrounding air, respond to the CO2 meter threshold, and ensure your safety and health.

    Storm Glass Weather Predictor Weather Station

    Original price was: £21.96.Current price is: £19.96.

    Storm glass or weather forecast bottles are a device invented by navigators in the 17th century to predict weather changes to predict storms. Although this is a great invention, the inventors were not known to the general public at the time.

    Later, the equipment became popular in 1860 under the propaganda of the then British Navy Admiral general: Robert FitzRoy (Director of the British Meteorological Agency).

    A sealed glass container is filled with a transparent solution of several chemicals. According to changes in external temperature and weather, different types of crystals will appear in the bottle3 Sizes available
