Koganei Digital Pressure Switches GS6 Series

Manufacturer: KOGANEI CORPORATION

Features

This small pressure switch delivers high reliability and fast response for both vacuum and positive pressure. At the same time, it maintains stable performance even when operating conditions change. To improve usability, the two-screen display shows values clearly during operation. As a result, users can confirm settings quickly and with confidence. In addition, the three-color indication system simplifies monitoring. Therefore, operators can control the device easily and accurately in daily use.
