Used for visual field testing of masks, face masks, respirators, etc.
GB/T 32610-2016 、GB 2626-2006
1. The overall equipment consists of a testing spherical screen, recording device, seat frame, testing head mold, etc.
2. Test spherical screen: radius 300-305mm, with a scale line extending to 120 ° every 10 °. The testing of the spherical screen directly has relevant marking lines, without the need for customers to perform complex and tedious marking. The field of view test can be directly projected onto the spherical screen, allowing for a visual inspection of whether the field of view is qualified.
3. Recording device: The recording needle is connected to the visual object through components such as a shaft and wheel, and records the orientation and angle of the visual object correspondingly on the field of view drawing.
4. Seat frame: used to support the semi-circular arch and fix the recording device.
5. Test head mold: A standard head mold with small light bulbs installed in the two eye holes of the head mold. The position of the light bulbs and the placement of the head mold shall comply with the requirements of standard GB2890. The installation position of the test head mold on the workbench should be such that the left and right eyes are placed at the center of the test spherical curtain, and the "0" point should be directly viewed.
Used for testing the visual effects of daily protective masks, face masks, gas masks, and other equipment. Applicable to labor safety protection inspection centers, medical device and drug inspection centers, disease prevention and control centers, textile testing centers, mask and mask production enterprises, etc.

1. The instrument hemisphere is made of acrylic plate, which has excellent weather resistance and good transparency.
2. The standard headform conforms to the average field of view for adults.
3. The base frame support is made of aluminum profiles, which are beautiful and durable.
Used to determine whether the field of view below the mask meets the requirements.

1. Using light induction sensor technology, accurately detect and calculate the test results based on experimental principles.
2. Direct computer operation, 3D real-time display of field of view.
3. The testing speed is fast, and each sample produces results in 2 to 10 minutes (determined by the set speed).
4. The head mold can switch between automatic movement of left and right eyes, and can also rotate left and right 15 ° automatically.
