Smoke Visibility Tester: Smoke Detection The test device is comprised of a plywood chamber with an inner side painted with heat-resistant paint and a hole in the ceiling that allows a light metre cell to be held while being tested. The chamber's bottom has a hole that lines up with the hole in the ceiling. The bottom hole has a clear glass bulb installed in it. A hole is present on the chamber's left side, and an exhaust fan has been mounted there. A hole on the right side allows air to circulate when smoke is being expelled into the chamber. A hinged door with a transparent glass pane is on the front of the chamber. The right-side and left-side holes of the chamber each have shutters. An electronics regulator installed in the instrument panel is used to control the LUX of the bulb. The black drape covered the front glass window and the hole in the ceiling. On the section stand, the chamber was mounted. The device comes with a LUX metre for measuring the LUX of the light. The device also comes with a stainless steel plate and an aluminium silicate plate. A stainless steel specimen frame with provisions to hold the specimen and slide the specimen frame is slanted at a 20�° angle to the vertical. On the chamber's bottom, a burner is fixed at a 45-degree angle. For the purpose of adjusting the gas supply, a flow metre, pressure gauge, and pressure regulator are installed on the section frame. For long-lasting corrosion resistance, all the pieces have been coated or polished. No gas will be included with the instrument from our end.
ASTM D2863 Oxygen Index Oxygen Index: Measuring the Minimum Oxygen Concentration to Support Candle-Like Combustion of PlasticsThe purpose of ASTM D2863 is to establish the lowest oxygen concentration in an oxygen/nitrogen combination necessary to sustain a flame burn on a plastic specimen. Real end use circumstances are not correlated. The test sample is placed vertically in a glass chimney, and a flow of oxygen and nitrogen is created there by starting at the bottom of the chimney. The test sample's top edge is lighted, and when the oxygen concentration in the flow falls, the flame eventually goes out. Specimen dimensions: Depending on the kind of material being tested, there are six requirements for the test specimen.

SPD-V010 Handheld Roll Gap Checker Overview The handheld roll gap checker is specially used to measure the length between spherical surface, arc surface and plane (or spherical surface). It is specially suitable for the opening adjustment of the roll gap of the metallurgical continuous casters in various specifications, because the roll gap checker has the advantages of high resolution, accurate measurement, stable data and easy to use. Because the opening accuracy of the roll gap checker will directly affect the quality of the casting block, this roll gap checker is an indispensable testing equipment in the continuous casting equipment, which can fully meet the needs of on-site installation testing and use process verification. When the hand-held roll gap meter smoothly passes through the gap between the guide rolls of the continuous casting machine, the upper measuring contact of the hand-held roll gap checker contacts the inner arc roll and the lower measuring contact touches the outer arc roll. The handheld roll gap checker is used in perpendicular to the roll diameter direction, during the pushing process, when the hand-held roll gap meter is in the tangent plane of the upper and lower rolls, the measured value is the smallest at this time, and this value is the roll gap measurement value. The design of the hand-held roll gap gauge ensures that the upper and lower contacts of the roll gap checker can smoothly pass the measured roll along a straight line during measurement. During the measurement process, the roll gap measuring instrument automatically compares the measured values, and displays the minimum measured value on the instrument display interface, which is the current measured roll gap value. The technical parameters 1. Measuring range of instrument type handheld roll gap checker: 180mm - 400mm (the range can be customized) 2. Measuring range of digital hand-held roll gap checker: 120mm - 400mm (the range can be customized) 3. Measuring range of hand-held thin slab roll checker : 60mm - 150mm (the range can be customized) 4. Measurement accuracy: 0.01mm 5. Working temperature: 25 85 6. Battery capacity: 5000mAh 7. Charger specification: 12V
