Adobe Acrobat Reader(Ver.6 or a later version)is required to open PDF files.

Leak tests on items subject to internal pressure such as compressors and gas piping have conventionally been performed by methods such as the water immersion method or halogen test. However with the product quality improvements and production rationalization of recent years, users are demanding leak inspection equipment that provides more reliability and uses smaller and simpler system devices. HELIOT model 102 is a specialized sniffer leak tester that offers high-precision testing in a compact/space-saving, low-cost design.

•Use of helium gas for electrical measurement enables leak tests with high precision, stability and reproducibility.

•Compact/lightweight design fits in palm of hand, and touch-panel display is easy to operate and read.

•Dry pump type is available (comes with built-in membrane pump).

•Highest level of response. Easy-to-operate suction probe is provided standard.

•Tester is driven by DC power supply, for outstanding portability and easy startup in field service applications.

•Quantitative tests replacing methods such as water immersion method : Automotive industry, air-conditioning/refrigeration industries, etc.

•High-precision tests replacing air leak tests : Air-conditioning/refrigeration industries, electric appliance/electronics/semiconductor industries, etc.
