How to solve the problem of shortage of constant temperature and humidity box of flow
If in the constant temperature and humidity box of flow is insufficient, how to solve? At the time of operation and constant temperature and humidity box, always meet the problem of insufficient compressor exhaust, how should solve? Then Tony instrument by us small make up to fight experience to tell you how to solve this problem! First, inlet filter failure: 1) Fouling blocking 2) Reduce displacement 3) The suction is too long (4) Pipe diameter is too small, the increase of the suction resistance affects the volume, to clean the filter regularly. Second, compressor speed reduces reduce displacement: 1) Air compressor use undeserved, because of air compressor exhaust is according to certain altitude, design of suction temperature and humidity of 2) When using it in exceeds the standard on the plateau, inspiratory pressure reducing, displacement will reduce. Three, cylinder, piston, piston ring wear, super bad, make relevant clearance increases, increase leakage, affected the displacement. Fourth, the stuffing box is lax, produce a flat lower the volume. 1) The first reason is the gland itself made unsatisfactory; 2) Second may be due to the installation, is bad for the piston rod and stuffing box center, develop blemishes, strain cause air leakage; 3) Generally in filling grease in the packing, it can play the role of lubrication, sealing and cooling. Five, high low temperature test chamber compressor suction, exhaust valve fault influence on displacement. Six, between valve seat and valve disc fell into pieces of metal or other sundry, lead to closed lax, form a gas leak. Seven, valve spring force of matching with the bad. Eight, the clamping force of pressure valve. Pressure force is small, flat, too tight or not, of course, can make the valve cover deformation and damage. If in the constant temperature and humidity box of flow is insufficient, how to solve? Through the above Tony instrument small make up in detail, the user should have a clear on this issue solution!

GESTER focuses on three key elements—process, people, and technology—the authors found that people of two seemingly opposite cultures are able to work together in a project-based environment to complement each other and reap mutual benefits for a win-win result.
Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
