Wintact WT8812 Compound Gas Monitor Detection Alarm, WT8812

1. Gas measurement: The sensor heats up when the countdown starts. The refresh rate is 1Hz. Do not charge when measuring combustible gas, otherwise it may explode.
2. High/Low Alarm: 4 default high/low alarms, 4 types of alarms, and the alarm sound can be turned off.
3. Data recording: 1000 pieces of data can be recorded. The default interval of data recording is 5 seconds, which can be set in INL of the setting mode. When the interval is set to 0 seconds, the data recording function fails. The clear operation will erase all the recorded data.
4. Temperature display: Set the unit to Celsius or Fahrenheit, the default unit is Celsius
5. Auto shutdown: Automatically shutdown without operation within 30 minutes. This function is enabled by default.
6. Battery capacity: It is forbidden to start the unit to avoid measurement errors or explosion. If the battery is low, it may automatically shut down. Charging time: about 4 hours. Discharging time: about 8 hours.
7. Zero-point calibration: It is recommended to calibrate the device at zero point or zero offset every month to ensure the high accuracy of measurement (make sure the battery power is more than 2bar) calibration and place it in the air for a period of time after power on. Make sure the body temperature of the device is slightly higher than the room temperature.
8. Temperature compensation: The measured data is compensated in the range of -20 to 50 degrees Celsius
9. Software error: The machine crashes/shuts down indicates that an error has occurred during operation. If the software is forced to shut down, press the ON/OFF button to activate the device
10. Adopt high quality gas sensor, safe and reliable, accurate measurement and stable performance.
11. It has excellent sensitivity and repeatability, is easy to operate and maintain, and meets the requirements for high equipment reliability in industrial field safety monitoring.
