Cara menggunakan
- Pilih Celsius atau Fahrenheit sebelum memasukkan nilai.
- Masukkan suhu udara, kelembapan relatif, suhu permukaan dan masa yang dirancang untuk kerja itu.
- Semak titik embun, jurang suhu dan keputusan OK / Berhati-hati / Tahan.
- Salin pautan perkongsian apabila anda mahu menghantar input yang sama kepada orang lain.
Formula
- γ = ln(RH / 100) + (a × T) / (b + T)
- Td = (b × γ) / (a - γ)
- Gap = permukaan suhu - titik embun
Catatan
- This checker is a practical field aid, not a substitute for produk data sheets, laman specifications, or supervisor instructions.
- Weather can change quickly. Recheck the permukaan suhu if the sun, wind, or cloud cover changes.
- All calculations stay in the pelayar. No input is sent to the server.
Soalan Lazim
Mengapa is the threshold 3°C / 5°F?
It gives a practical buffer above the titik embun and is mudah to remember on laman.
Mengapa is planned time not part of the calculation?
The decision should be based on measured suhu and kelembapan. Planned time is recorded only as a reminder.
Can I use Fahrenheit?
Yes. Switch the unit system and the alat will keep the same physical temperatures when you change units.
What does Berhati-hati mean?
The permukaan is still above the titik embun, but the margin is too small for a comfortable cat window.
What if kelembapan is 100%?
The titik embun will match the udara suhu, so the permukaan must be clearly warmer to avoid kondensasi risk.
