• Stringent leak test (2 x 10-8 Pam3/sec)
100% leak test is conducted before shipping, using a helium leak detector.
• Use of a precision needle
The incorporated non-rotary type needle provides precise, smooth control of minute flows.
• Compatible with both gases and liquids
• Superior temperature characteristic
Flows are scarcely affected by ambient temperature fluctuations, remaining within an insignificant range of flow variations.
This superior temperature characteristic is applicable to gases only, and not to liquids, because the viscosity of a liquid may greatly vary depending upon the temperature conditions.
