Frequency crystal sensor for thin film evaporation

Product Detailed

Related Categories:Sensors

Usage:

Use for crystal monitor system.

The monitor system can catch the evaporation rate by dint of this crystal.

Characteristic:

1. This crystal can take stability frequency and detect the shift of evaporation amount.

2. This crystal has been steady for temperature variation because of using AT cut crystals.

3. You can request for frequency extent.

4. We can make your frequency spec. Please request to us if you need special spec.

*We are using the special equipment for measure frequency, resistance amount and curvature.

Our usual products specification are as follows:
