Vacuum Degassing Oven, VDO Touch

The vacuum degassing oven (VDO touch) is used to precisely and accurately degas pressure-aged binder samples and is designed for rapid removal of entrapped air bubbles in asphalt specimens to the required 15 ±1.0kPa (25.5Hg). The network-ready 7in (178mm) touch-screen controller features easy menu-driven operation in multiple language options for fast programming of vacuum, temperature values and soak times. The controller display indicates time, temperature, and current process stage, with alerts at the end of each test. When connected to a network with an Ethernet cable, the VDO Touch can be operated remotely via smart phones, tablets, or PC’s. USB Ports allow easy software upgrades.

Soak and degassing times are both programmable up to 4,320 minutes. The rugged stainless steel cabinet, chamber and cover are easy to maintain, and the removable cover features a heat-resistant glass viewing window for monitoring purposes The VDO includes (4) 236ml (8oz) sample tins, and a specimen removal tool for easy loading and unloading of samples.
