CAution/notiCe:
This product is designed for application in an ordinary environment (normal room temperature, humidity and atmospheric
pressure). Do not use this sensor under the following conditions as these factors can deteriorate the product characteris-
tics and cause failures and burn-out.
• Corrosive gas or deoxidizing gas - (chlorine gas, hydrogen sulde gas, ammonia gas, sulfuric acid gas, nitric
oxides gas, etc.).
• Volatile or ammable gas.
• Dusty conditions.
• Under low or high pressure.
• Wet or excessively humid locations.
• Places with salt water, oils, chemical liquids, or organic solvents.
• Where there are excessively strong vibrations.
• Other places where similar hazardous conditions exist.
Use this product within the specied temperature range. Higher temperature may cause deterioration of the characteris-
tics or the material quality of this product.
* Hardware can not withstand negative voltage. Please take care when connecting a power device.
** At temperatures above 100ºC, it is possible for the board circuitry to lose programmed memory.
*** If application exceeds 1 mA the sensor will return a maximum reading of 1 mA.
If current applied to measurement port exceeds 2 mA, circuit protection and conditioning is required.
