1.9 CF ECO Vacuum Oven | 5 Shelves, Four-Wall Heating, 120V 800W

What Comes With a 1.9 CF ECO Vacuum Oven The chamber is polished stainless at 14.25 by 16.5 by 13.75 inches inside. Outside it measures 28 by 22 by 18 inches and weighs 205 lb, so it is a two-person lift. Five removable shelves come as standard, and the chamber accepts up to eleven. Each shelf gives 129 square inches, which is about 645 square inches as supplied. Heating is on all four walls, through an LED PID controller. Range is room temperature plus 18 Fahrenheit up to 212 Fahrenheit, held to plus or minus 1.8 degrees. An over-temperature alarm and an automatic overshoot shutdown are both fitted. The door carries a half-inch tempered glass window at 11.75 by 11 inches, with integrated LEDs. The gasket is silicone and replaceable, which matters more than anything else on a vacuum door. Electrical is 120 volts at 60 hertz drawing 800 watts, on a USA plug. What an External Vacuum Pump Has to Do Here An external vacuum pump is required, and that is the single most important line to read. The oven gives you a sealed, heated chamber and a port, and nothing that moves air. The port is a quarter-inch JIC fitting, and a five-foot HVAC hose comes in the box. A USA power cord and an operation manual come with it as well. Now the vacuum numbers. The chamber holds a deep vacuum below 0.1 torr. The fitted gauge reads from minus one to minus thirty inches of mercury. Reading that depth takes a micron gauge rather than the fitted inHg gauge. Maximum vacuum is minus 29.9 inches of mercury, or 75.4 centimetres of mercury. Leak rate is under one inch of mercury lost over twenty-four hours. That is the figure worth testing on arrival, because it is the one that ages. Key Features Chamber 14.25 x 16.5 x 13.75 in: Polished stainless steel, behind a half-inch tempered glass door.
