隔絕管 / Shielding tube

ProboStat

The ProboStat™ can be delivered with an stainless steel enclosing tube welded on a socket. The tube either replaces the standard alumina/quartz enclosing tube, or is mounted on the outside of this tube.

氧氣感測 / Oxygen sensors

The use of controlled atmospheres during measurements at high temperatures is a specialty of the ProboStat. Nevertheless, the establishment of controlled atmospheres is not entirely trivial. This is mainly done before the gas enters the ProboStat, and may require one or more of prefabricated gas mixtures, gas mixing, total pressure control, electrochemical pumping, wetting, and drying and other filtering/gettering.

客製化加熱方案 / Custom heating solutions

• gas line heating,
• membrane heating,
• uniform or non-uniform heat regions,
• heat gradients,
• low voltage heating,
• heat radiation,
• heat conductance,
• heat convection.

維修包 / Repair kit

Feedthrough replacement kit is used for on-site replacement of electrical mini-contact feedthroughs.

液態系統 / Liquid Cell Accessories for ProboStat

The ProboStat™ system can be equipped with a liquid cell accessories to measure the dielectric constant of liquids at elevated temperature.

Typical use:

• Dielectric measurements of liquids at RT - 200°C
• Replaces a standard sample support tube assembly 
• Use in combination with e.g. heating mantle 
• ca. 0.1 – 0.5 ml measured volumes

高溫熔融固體電池 / High-temperature melting solids cell

Typical use:

• Dielectric measurements of solids and liquids up to 1250 °C
• Replaces a standard support tube assembly 
• volume: up to ca. 0.25 ml

高壓系統 / High pressure modification

High temperature resistant stainless steel by special order. Such tubes can be used for above-atmospheric pressures, as standalone outer enclosing tubes, or as a safety container around a ceramic enclosing tube when this is subjected to above-atmospheric pressures or explosive/toxic/corrosive gases that must not escape in case of breakage of the ceramic tube. 

The tube is made of the alloy 253 MA. This alloy has good oxidation resistance to 1100°C in dry air.

內部加熱 / Internal heater

There are two ways of creating a temperature gradient across the length of a standard bar sample. The simple way is to move the sample slightly away from the center of the hot zone in the furnace. Another possibility is to install an internal heater. The first method is the most common way to do it and is a reliable method as long as you wait until the conditions have stabilized before doing the measurements. An internal heater can be bought separately either with or without a power supply.

大尺寸樣品 / Setup for measurements on large samples

The ProboStat™ setup for measurements on large samples has been developed for measurements on disk samples with diameters in the range from 25 up to 60 mm. It can be operated under controlled atmosphere in single atmosphere mode, and temperature range RT-1600 °C.
