The HM-923 VDO Touch by ATS is an automated tabletop degassing oven with an internal vacuum system, 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 smartphones, tablets, or PCs. USB Ports allow easy software upgrades.
Temperatures in the VDO Touch vacuum chamber are measured by a platinum RTD probe with a range from ambient to 200°C with accuracy to ±5°C. Soak and degauss times are both programmable for 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 chamber holds eight 4oz (118ml) or four 8oz (236ml) sample containers and comes with four 236ml (8oz) sample tins and a specimen removal tool for easy loading and unloading of samples.
