Temperature:
When the temperature is below 0℃, it is uploaded in the form of a complement.
FFB5 H (hexadecimal)=-75=>Temperature = -7.5℃
Humidity:
167 H (hexadecimal)=359=>Humidity=35.9% RH
Ammonia:
When the range is 50ppm
0064 (hexadecimal)=100=>Ammonia=10 ppm
When the range is 100ppm or 500ppm
0064 (hexadecimal)=100=>Ammonia=100 ppm
Equation between ppm and mg/m3 (@25℃, 1 bar)
X ppm = (Y mg/m3)(24.45)/(molecular weight) or Y mg/m3 = (X ppm)(molecular weight)/24.45
For NH3 calculation only:1ppm=0.70mg/m3 1mg/m3=1.44ppm
1) Do not apply this device to systems involving personal safety.
2) Do not install the device in a strong convective air environment for use.
3) Equipment should avoid contact with organic solvents (including silicone and other adhesives), coatings, chemicals, oils, and high concentration gases.
4) Equipment cannot be used in environments containing corrosive gases for a long time, as corrosive gases can damage sensors.
5) Do not place the device in high concentration organic gases for a long time, as long-term exposure may cause the zero point of the sensor to drift and slow recovery.
6) Prohibit long-term storage and use in high concentration alkaline gases.
7) Although this product has high reliability, we recommend checking the equipment's response to the target gas before use to ensure on-site use.
