Easily and quickly get control of how high the CO2 and the relative humidity are in your home. The PTH-5 and PTH-8 Wi-Fi both display CO2, relative humidity and temperature. All 3 pieces of information are displayed clearly and distinctly on the large screen in a stylish Scandinavian design.

CO2 is displayed in PPM and is illustrated with a happy smiley/green light if the air is fresh and contains little CO2 (400-700ppm), a satisfied smiley/yellow light at a CO2 level that is between (700-1500ppm) and a sour smiley/red light at a CO2 level (+1500 ppm) that can cause headaches etc.

The relative humidity is displayed in the range 0-80 percent with an accuracy of plus / minus 5 percent. Notice that they may be calibrated slightly differently, so when you place them next to each other, they may show slightly different, but all go up and down together with the humidity.

We have two models of the CO2/humidity meter. The difference between PTH-5 & PTH-8 Wi-Fi is that PTH-8 has Wi-Fi. Via Wi-Fi, the information can be stored in the Tuya Smart app, where you can also use the information to make your home more intelligent or simply access your historical data.

The CO2 measurements can help you ventilate or turn up the ventilation before you get a headache and help children and others not feel bad due to bad indoor air. You can also find patterns in when CO2 becomes high and perhaps see if your headache might be due to an elevated CO2 level.

It is important to control the relative humidity indoors, as mold grows in and on organic material already when the humidity is above 70%. You can quickly check the humidity with this simple humidity meter.
You can use it to see when the humidity is so high that you need to ventilate and which method provides the best ventilation. It is also suitable for adjusting mechanical ventilation.

The moisture meter is easy to operate, there are only 2 buttons to keep track of, and is designed so that it can be placed on a table, a shelf or anything else 3.

Our hygrometer pays for itself many times over, by ensuring that you know the humidity, know how to keep it down and help prevent problems with e.g. mould.

It is charged with the associated USB cable. There is a built-in lithium battery of 2400 mAh.

It comes in dark gray as in the first picture. The display is identical.
