Altronic 45PHL

The Altronic 45PHL series pressure switch-gauges offer a new standard for a mechanical pressure gauge with high/low switch contacts. The 45PHL series uses a special helically-wound coil of Inconel, directly connected to the indicating pointer. Fewer parts, fewer problems.

The features of the Altronic 45PHL series pressure switch-gauges make them ideal for gas compressor and other high pulsation/vibration use.

The 4-1/2 inch round, weather-resistant case fits an industry-standard panel cutout allowing easy replacement of OPLFC gauges.

These are a few samples out of an extended variety of products Hatraco has to offer. For more information please contact us.
