4. Setup
4.1 Unpacking
Carefully remove the TH-100 Fog Meter and all accessories from its packaging. Verify that all items listed in the 'What's in the Box' section are present:
- HNZXIB Color Spectrum Fog Meter TH-100
- 0% Calibration cover
- Power adapter
- Instruction manual
- Fog meter calibration report
4.2 Power Connection
Connect the provided power adapter to the 'Power Input' port on the instrument and then plug it into a suitable power outlet.
4.3 Initial Calibration (0% Calibration)
Before first use or after relocation, perform a 0% calibration to ensure accuracy. The instrument does not require a warm-up period, providing data within 2 seconds.
- Ensure the test port is clean.
- Place the 0% calibration cover securely over the test port.
- Follow the on-screen prompts to initiate the 0% calibration.
The instrument's unique optical technology is designed to be unaffected by ambient light, minimizing external influences on test values.

5. Operation
5.1 Basic Haze and Transmittance Measurement
The TH-100 measures both haze and transmittance. The 5-inch TFT LCD display provides intuitive test results.
- Power on the instrument using the On/Off button.
- Ensure the instrument has been calibrated (see Section 4.3).
- Place the sample to be measured over the test port. For soft films, use a film clamp to flatten the sample.
- Press the 'Enter' button to initiate the measurement.
- The haze (H) and transmittance (T) values will be displayed on the screen.

5.2 Sample Preparation and Placement
The TH-100 features an open test area, accommodating various sample sizes. The routine test diameter is 21mm, with customizable options for 5mm, 7mm, or 10mm aperture boards.

Figure 5: Open Measurement Area and Customizable Apertures
For soft films, use a film clamp to ensure the film is flat and taut over the test port. For rigid samples like glass or plastic sheets, simply place them directly over the test port.

5.3 Horizontal Measurement for Large Samples or Liquids
The TH-100 can be laid down for horizontal measurement, which is ideal for large samples or liquid samples that cannot be easily placed vertically.
- Carefully lay the instrument on its side.
- For liquids, use a suitable cuvette or container and place it in the designated liquid measurement area.
- Proceed with the measurement as described in Section 5.1.
5.4 Data Output and PC Connection
The TH-100 can store up to 20,000 values and can be connected to a computer for data management and report generation.
- Connect the instrument to a computer using a USB cable.
- Install the provided PC management software (Haze QC).
- Use the software to view, analyze, and print data reports.
