Thermal Sensor Options

The MH-T675 is offered with two thermal detector options.

384 × 288 Sensor

The 384 × 288 configuration may provide a more cost-effective option for general thermal observation and monitoring.

640 × 512 Sensor

The 640 × 512 configuration provides a higher native pixel count, which may support:

• Greater visible detail

• Improved subject separation

• Better image quality during digital zoom

• Clearer viewing of smaller heat sources

• More detailed long-distance observation

Each sensor version should have a separate SKU and price.

12 μm Pixel Pitch

The thermal detector is listed with a 12 μm pixel pitch.

A smaller pixel pitch can support compact lens systems and higher apparent magnification, although overall image quality also depends on:

• Sensor resolution

• Thermal sensitivity

• Lens quality

• Image processing

• Display resolution

• Environmental conditions

Lens Options

The MH-T675 may be configured with:

• 35 mm F1.0 lens

• 50 mm F1.0 lens

• 75 mm F1.0 lens

35 mm Lens

A 35 mm lens generally provides a wider field of view and may be suitable for closer-range scanning and broader-area observation.

50 mm Lens

A 50 mm lens provides a balance between field of view and observation distance.

75 mm Lens

A 75 mm lens generally provides a narrower field of view and increased apparent subject size for longer-distance observation.

Exact field-of-view and detection-distance specifications should be assigned to each lens separately.

Field of View

The listed field of view is approximately 5.9° × 4.79°.

This value likely applies to only one sensor and lens combination. Confirm the correct field of view for:

• 384 × 288 with 35 mm lens

• 384 × 288 with 50 mm lens

• 384 × 288 with 75 mm lens

• 640 × 512 with 35 mm lens

• 640 × 512 with 50 mm lens

• 640 × 512 with 75 mm lens

OLED Display

The internal OLED display provides a listed resolution of 1024 × 768 pixels.

Potential benefits include:

• High contrast

• Clear menu visibility

• Detailed thermal-image presentation

• Smooth viewing in low-light conditions

• Improved performance in cold environments

Confirm display brightness levels, diopter range, eye relief, and refresh rate before publishing.

Electronic Zoom

The device supports:

• 1x electronic zoom

• 2x electronic zoom

• 4x electronic zoom

Digital zoom enlarges the displayed image but does not increase the detector’s native resolution. Image clarity may decrease at higher zoom settings.

Optional Laser Rangefinder

An optional laser rangefinder provides a listed measuring distance of up to approximately 1,300 m.

Before publishing, confirm:

• Minimum ranging distance

• Maximum ranging distance

• Measurement accuracy

• Laser classification

• Measurement units

• Continuous ranging mode

• Angle measurement

• Weather limitations

• Whether the rangefinder is included or optional

The rangefinder version should be listed as a separate product variant.

Thermal Colour Palettes

The listed thermal display modes include:

• White Hot

• Black Hot

• Red Hot

• False Colour

• Outline or Stroke Mode

Different palettes can help users interpret thermal scenes under different conditions.

The exact names and number of available palettes should be verified from the final firmware.

Wi-Fi Image Transmission
