SONIO高温耦合剂是超声波测厚仪、超声波探伤仪在测量高温物体时必须选择使用的耦合剂，选择高温耦合剂要根据自己现场的具体高温温度段选择合适的耦合剂，SONIO高温耦合剂有Thermasonic、Sono 600、Sonotemp、Pyrogel、Sono 900、Sono 950、Sono 1100、Sono 1200+多个型号，具体参数见如下：

HIGH TEMPERATURE ULTRASONIC COUPLANTS
Sonotech offers a broad range of extended and extreme temperature ultrasonic couplants ranging from -60º to 1200º F. Some of the products in this category have proven themselves for over 25 years. Sonotech couplants do NOT contain perflourocarbons found in many "high temperature" greases, thus "polymer fume fever" is not an operator hazard.Thermasonic、Sono 600、Sonotemp、Pyrogel、Sono 900、Sono 950、Sono 1100、Sono 1200+
SONO 950 High Temperature Couplants
SONO 950 provides coupling for thickness gaging and flaw inspection at high temperatures. SONO 950 will maintain acoustic coupling beyond 15 seconds to give ample time for obtaining good thickness readings. In most cases, the signal strength actually increases with time to the point of thermal decomposition.
Note: For best results, allow a few seconds of "melt time" before taking reading. Signal attenuation may occur if used at lower than recommended temperatures.
SONO 950
- Less smoke than SONO 900
- Provides an extended time window for longer inspections
- Non-toxic, non irritating formula provides inspection safety
- Medium viscosity paste
- No Perfluorocarbons
