GHS-02 Gradient Heat Seal Tester\u2019s PLC control unit and HMI touch screen, ensure good sealing results with our state-of-art design, and it can realize five groups of sealing temperatures simultaneously.<\/p>\n<p>1. Both the upper and lower jaws are made of aluminum and independently heated so that heat loss is maximumly eliminated in sealing and temperature smoothness is ensured.<\/p>\n<p>2. First class P.I.D. (proportional integral derivative) temperature controller for optimal heating management.<\/p>\n<p>3. Achieve accuracy with proximity and pressure sensor, ensuring controlled dwell time and sealing pressure.<\/p>\n<p>4. Unform sealing pressure by the three-way guided sealing bar.<\/p>\n<p>5. User protection designs, such as anti-scald front cover, manual and foot switch, etc.<\/p>\n<p>6. Seal jaw customization available in terms of dimension, shape, and sealing surface\/patterns.<\/p>\n<p>7. More gradient temperatures of upper and\u00a0lower heating can be customized. 8.Seamlessly connect through the RS 232 port and professional software (optional).<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-medium wp-image-549\" src=\"https:\/\/www.materialstests.com\/wp-content\/uploads\/2025\/12\/GHS-02-Gradient-Heat-Seal-Tester-300x188.jpg\" alt=\"M\u00e1y ki\u1ec3m tra h\u00e0n nhi\u1ec7t theo \u0111\u1ed9 d\u1ed1c GHS-02\" width=\"300\" height=\"188\" srcset=\"https:\/\/www.materialstests.com\/wp-content\/uploads\/2025\/12\/GHS-02-Gradient-Heat-Seal-Tester-300x188.jpg 300w, https:\/\/www.materialstests.com\/wp-content\/uploads\/2025\/12\/GHS-02-Gradient-Heat-Seal-Tester-768x480.jpg 768w, https:\/\/www.materialstests.com\/wp-content\/uploads\/2025\/12\/GHS-02-Gradient-Heat-Seal-Tester-600x375.jpg 600w, https:\/\/www.materialstests.com\/wp-content\/uploads\/2025\/12\/GHS-02-Gradient-Heat-Seal-Tester.jpg 800w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<h2><strong>3.Why do you need GHS-02 Gradient Heat Seal Tester<\/strong><\/h2>\n<p>Heat seal test is a time-consuming lab test, especially the adjustment of sealing temperature. Operator needs to wait for temperature to reach the desired level. This makes GHS-02 Gradient Heat Seal Tester an ideal tool in improving efficiency in testing, because of the five-temperature gradation that can be realized at the same time.
