Pressure and Temperature Sensors

Plus technology provides advancements in vessel engineering and new pressure and temperature sensors, ensuring complete digestions, reproducible results and safety in the microwave accelerated reaction system (MARS) 5 microwave digestion system. The HP-500 Plus and XP-1500 Plus vessels are designed to work with pressure and temperature sensors to provide control for sample processing. Easy-to-assemble and versatile, they may be converted from fully sealed to self-venting vessels by simply changing their covers.

The HP-500 Plus (high-pressure) vessels deliver throughput and ease-of-use for routine applications with fast, complete, and reproducible digestions ensured every time. The vessel's compact design processes up to 14 high pressure (500 psig) digestions at once and can handle temperatures up to 260°C. Vessel liners are composed of Teflon and are ideal for many types of samples including soils, metals and water.

The XP-1500 Plus (extensive pressure) vessels can process up to 12 samples simultaneously under the highest pressure (1500 psig) or temperature (300°C) conditions. vessel liners are available in either Fluoropolymer or quartz and are ideal for the difficult matrices such as oils, heavy organics, hazardous wastes, refractory materials, ceramics, and ores.

Additionally, sensor technology is available that features flexible, non-metallic, microwave transparent temperature sensors that can read up to 300°C and provide true internal pressure measurements. External sensors are also available that provide a visual display of the termperature in each vessel as it passes over the sensor window in the cavity floor of the unit.
