3. MMP20 Operating Steps

3.1 Power On and Warm-Up

  1. Press the power button; the instrument self-checks and displays the current humidity value.
  2. It is recommended to warm up for 5–10 minutes to ensure sensor stability.

3.2 Measurement and Reading

  1. Insert the sampling probe into the gas or liquid pipeline to be measured.
  2. Wait for the reading to stabilize, and record the dew point temperature or volume ratio humidity.
  3. If necessary, use the conversion table in the Chinese manual for unit conversion.

3.3 Power Off and Storage

  1. Remove the probe, clean it, and dry it.
  2. Long press the power button to turn it off, and store it in a dry environment.

4. Maintenance and Precautions

  • Regular calibration: It is recommended to send for inspection or use standard gas for calibration every 6–12 months.
  • Avoid condensation: When measuring high-temperature and high-humidity gases, ensure the probe temperature is above the dew point.
  • Clean the probe: Gently wipe with a soft cloth dipped in anhydrous ethanol; do not scrape with hard objects.
  • Battery care: If not used for a long time, charge once every 3 months.

5. Frequently Asked Questions (FAQ)

5.1 What should I do if the MMP20 displayed value fluctuates greatly?

Check whether the probe is contaminated or has condensation; clean and dry it, then warm it up again. If it still fluctuates, refer to the Chinese manual for calibration.
