Cum se folosește
- Choose Celsius or Fahrenheit before entering values.
- Enter air temperature, relative humidity, surface temperature, and the planned time for the job.
- Check the dew point, the temperature gap, and the OK / Atenție / Oprire decision.
- Copy the share link when you want to pass the same inputs to someone else.
Formulas
- γ = ln(RH / 100) + (a × T) / (b + T)
- Td = (b × γ) / (a - γ)
- Gap = surface temperature - dew point
Note
- This checker is a practical field aid, not a substitute for product data sheets, site specifications, or supervisor instructions.
- Weather can change quickly. Recheck the surface temperature if the sun, wind, or cloud cover changes.
- All calculations stay in the browser. No input is sent to the server.
Întrebări frecvente
Why is the threshold 3°C / 5°F?
It gives a practical buffer above the dew point and is easy to remember on site.
Why is planned time not part of the calculation?
The decision should be based on measured temperature and humidity. Timp planificat is recorded only as a reminder.
Can I use Fahrenheit?
Yes. Switch the unit system and the tool will keep the same physical temperatures when you change units.
What does Atenție mean?
Suprafața este încă peste punctul de rouă, dar marja este prea mică pentru o fereastră confortabilă de vopsire.
What if humidity is 100%?
Punctul de rouă va coincide cu temperatura aerului, astfel încât suprafața trebuie să fie clar mai caldă pentru a evita riscul de condens.
