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.
Brief introduction 1. Fast processor Cpu is msm7627 aa and the system adopts android 4.0 ics operating system. 2. Strong protection for bad environment It can apply to the bad environment, which can resist multiple dropping impact from 1.2m high; apply to ip65 protection grade with good water-proof and dust-proof effect; durable and long life span. 3. Visible 3.5 inch lcd in the sunlight It is 3.5 inch vertical screen lcd, 480*640 high resolutions; with pressure sensitive touch screen and semi permeable tft lcd readable display. Its particular non glare and reflective technology make the work in the wild sunlight more easy and convenient. 4. The storage capacity is big and extensible Tf card supports no less than 8g cards, which can basically satisfy regular information and data storage. It adopts portable change design. There is no need to open the tester and you can remove the battery with the knob. The battery capacity is as high as 6000 mah. 5. Advanced battery installation design and strong endurance Due to the lithium battery capacity of 6000 mah and low-power design, the duration will be more than 3 days under routine operation. 6. Multi-functional module integration --the built-in fixed network test module can do adsl test, lan test and modem emulation. --5 million pixels camera makes the image data collection convenient. --support bluetooth, which is convenient provide data transmission between any compatible electronic equipment. --built-in gps module can realize the position location. --support 1d/2d red light/ laser bar codes scan. 7. Reliable process design It adopts advanced manufacturing process which is reliable and convenient to assemble. Paper carton package.
