The Mask Visual Field Tester is designed to evaluate whether the field of vision under a mask meets standard requirements. It ensures that respirators, protective masks, and daily-use masks provide adequate visibility for safe and effective use. The instrument is widely used for quality control, R&D, and certification testing of mask products.
Application
The Mask Visual Field Tester is applicable to field-of-vision evaluation across the following industries and products:
(1) Respiratory Protection Industry: self-priming filter gas masks, anti-particulate respirators — evaluation of left, right, and overall field of vision
(2) Medical and Healthcare Industry: surgical masks, medical protective masks — verification of field of vision for safe usage
(3) Occupational Safety Industry: industrial and dust masks — ensuring visual range compliance for workers in high-risk environments
(4) Daily Protective Masks: general consumer masks — assessment of visual comfort and safety
(5) Research and Development: development of new mask models, optimization of visual field design
(6) Quality Control Laboratories: testing and verification of mask products against standard field-of-vision requirements
Standards
The instrument is compliant with the following standards:
(1) GB 2890-2009 – Respiratory protection — Self-priming filter gas mask, Section 6.8: Field of vision
(2) GB 2626-2019 – Respiratory protective products — Self-priming filter anti-particulate respirator, Section 6.10: Field of vision
(3) GB/T 32610-2016 – Technical specifications for daily protective masks, Section 6.12: Field of vision
Features
(1) Hemispherical surface of visual field, including holder, accurately measures left and right vision angles
(2) Standard head mold equipped with electric beads and control switch
(3) Spherical projection of field of vision for precise measurement
(4) Head mold can move left and right to simulate real-life mask usage
(5) Compact and portable design suitable for laboratory or production floor testing
(6) Provides objective verification of visual field compliance for respirators and masks
