Seitron M4 Be Cool Digital Manifold with Four-Way Valve Block
The Seitron M4 is an intelligent digital four-way valve manifold gauge with pressure and temperature measurement, leak test, vacuum measurement, and data logging. The Seitron M4 features an intuitive, large, easy-to-read 5” touchscreen color display, a rechargeable battery, and the ability to select from more than 80 refrigerants. The Seitron M4 digital manifold can be operated from the manifold or remotely controlled with the Seitron be cool Mobile App. The Seitron B4 Be Cool digital manifold is ideal for commissioning, servicing, and maintaining refrigeration and air conditioning systems and heat pumps.

Overview
The Seitron M4 digital manifold makes the installation and maintenance of refrigeration, A/C, and heat pump systems easier. Superheating and subcooling are important measurements to determine the performance and efficiency of the HVAC system, and the Seitron M4 has already preconfigured these parameters to assist in diagnosing potential issues. In addition, with the 4-way valve and automatic heat pump mode, you do not have to switch to different refrigerant hoses, making it easier for a technician to measure these parameters on a heat pump system.

During a tightness test, the Seitron M4 manifold measures the system pressure and ambient temperature for an interval of time. A technician can also set an alarm so that if the pressure decreases by a certain percentage during a set time frame, the manifold emits a sound that identifies the leakage situation. The M4 digital manifold will display the initial pressure, the current pressure, and the pressure difference.
The Seitron M4 manifold intuitive touch screen clearly shows the changes in vacuum, pressure, and temperature, and the graph display supports data monitoring and analysis in real-time. Up to 100,000 points of data can be recorded and exported by USB.
The Seitron digital manifold includes a collapsible rear hook for hanging and a sight glass to view the condition of the refrigerant passing through the system.
