wintact WT8822 Hydrogen Sulfide Detector

INTRODUCTION

Hydrogen sulfide (H,S) detector is novel-looking, compact and port­able, which is designed for detecting hydrogen sulfide concentration. It uses high-quality gas sensor to achieve accurate measurement, stable performance with safety and reliability. It meets stability requ­irement of industrial site safety monitoring on equipment’s high reli­ability, widely used in household, chemical industry, mining industry,
environmental protection, gas transmission and distribution, bioche­mical medicine, agricultural research and so on.

3. Maximum/minimum value made: Short press for maximum value, short press it again for minimum value, short press ii again to exit.

4. Unit switch: Short press to switch units among %VOL, %LEL, PPM, and (m)-

5. Setting: long press to enter setting mode, short press to switch setting items, short press and to switch on/off, long press to exit.

   • “ELE” temperature unit swit’aF
   • “OFF” limed shutdown switch
   •  “bu2” buzzer switch
   •  “HI/LO” alarm value setting
   • “CAL” calibration
     Note:
   1.  Temperature refers to the temperature of the hydrogen sulfide sensor.
   2. Timed shutdown is set as 10 minutes.
   3.  Buzzer switch refers to button pressing sound and alarm sound.
   4.  Alarm value setting: Short press and switch between high and low alarm point, long press – to set alarm point value, short /’£”;s [!] to switch setting digit, short press and to set alarm value, long press to save and exit.
   5.  Calibration: Short press and to switch calibration point. User can calibrates point unde environment (in normal temperature) by long pressing to start calibration. When calibration is finished, “PASS” will be displayed autom­atically; if not, “Err” will be displayed. After calibration.short press or , The”1 00″calibration points are factory calibrated and operate in a sealed environment filled with H,S concentration (uni is PPM). Long press button to start calibration, and wait for the concentration to stabilize (about 4 minutes) for automatic calibration or long press button to start calibration.When calibration is finished,”PASS” will be displayed;if not,”Err” will be displayed After successful calibr­ation, long press [1l_tc,_fine tune calibration value (by short pressing an ) and long press again to save calibration value and exit.
   6. Lock: Long press to lock “100” value of calibration point, and unlock for further calibration. (6) Unlock: Under power off state, short press , and at the same time to enter unlock interface. Short press to switch setting digit. Short press and to set value. User needs lo ask original factory for password, and long press to unlock and restart.

Warnings and Precautions

Improper operation or environment may cause accidents.

1. The instrument is strictly prohibited from collision, falling from high places or violent vibration.
2. If there is gas of high concentration, the instrument may not work properly.
3. Please operate and use strictly in accordance with the instructions, otherwise, it may result in inaccurate test results or damage to the instrument.
4. Do not store the instrument in the following environments:
5.  Places that may have water or heavy dust.
6.  The instrument must not be stored and used in environments that contain corrosive gases (such as salt or sulfur in high concentrat­ion, etc.).
7. Air with other gases or chemicals.
8. Places of high temperature, high humidity or direct sunlight,incl­uding environments of too high and low temperatures, high hum­idity, electromagnetic fields, and strong sunlight.
9. Cleaning of the instrument’s surface:
10.  The window of the sensor must be kept clean. If it is dirty, the measurement will be inaccurate.
11. Please wipe it gently with a clean, soft cloth dampened with water (do not use alcohol, diluent, etc. to clean the case, especially for the LCD window.).
12. In order to ensure accuracy, the instrument should be calibrated regularly, and the period can not exceed one year.
13. If the instrument breaks down, please contact our professional personnel to repair it. Other people shall not change components and wiring.
    Warning : prohibit charging or disassembling batteries in an explosive environment.
