Cost-Effective Safety: Prevent expensive repairs or tube replacements with this affordable and essential safety measure.
User-Friendly: Simple to install and maintain, making it perfect for both professionals and hobbyists.
The HT-30 uses a water flow switch mechanism to monitor cooling water flow through your laser tube. If the flow stops or drops below a safe level, the sensor triggers the laser power supply to shut down, preventing the laser from operating without proper cooling. This automatic protection keeps your laser tube safe and functional.
Install the sensor in the correct direction, ensuring water flows from the inlet to the outlet.
Use appropriate tubing and fittings for a secure connection to your water cooling system.
Double-check all connections to prevent leaks and ensure proper operation.
