The Leitenberger MG6H, MG8H, and MG1H type pressure gauges are high-quality instruments manufactured in Germany, specifically designed for the precise measurement of high and low pressures in refrigeration systems. These devices feature a surface (front panel) mounting capability with a back flange, ensuring easy integration and reliable operation in industrial and commercial refrigeration equipment.
Leitenberger's commitment to quality guarantees that these pressure gauges provide accurate and stable readings over the long term, even in the most demanding environments.
These pressure gauges feature several functions that optimize the supervision and maintenance of refrigerant systems:
Excellent Quality Design: The entire housing is made of stainless steel (INOX), which ensures excellent corrosion resistance and a long service life.
Glycerine Filled: The internal mechanism is filled with glycerine, which significantly dampens the effects of pressure surges and vibrations. This allows for more stable readings and protects the moving parts from wear.
Color Scale for Refrigerants: The gauge scale is color-coded, allowing for quick and intuitive identification regarding the operating pressure ranges belonging to different refrigerants (e.g., R134a, R404A, etc.).
Surface Mounting: The back flange enables the stable and secure mounting of the instrument on the front surface of control panels or instrument boards.
Durable Plexiglass Cover: The plexiglass cover (plexi) protecting the scale is lightweight, impact-resistant, and provides good visibility.
Bottom Connection: The connection elements are located at the bottom of the instrument, which simplifies the connection of pipes and hoses.

These precision pressure gauges are ideal for the following areas:
Refrigeration technology: Monitoring the pressure of industrial refrigeration units, cold rooms, commercial refrigerated counters, and freezers.
Air Conditioning Equipment: Monitoring the filling pressure and operating pressure of automotive and building air conditioning systems.
Process Technology: Industrial processes where reliable, vibration-resistant pressure measurement is required.
Maintenance and Service: Thanks to the colored scale, service technicians can quickly check systems based on the specified refrigerant specifications.
Filling Leitenberger manometers with glycerin is crucial for long-term accuracy. Sudden pressure surges and vibrations caused by compressors are common in refrigeration systems. The viscosity of glycerin effectively dampens these movements, preventing the gauge indicator from jumping, which would make accurate reading difficult. Furthermore, glycerin also functions as a lubricant, reducing friction and wear on internal mechanical components, thereby significantly extending the instrument's service life.
For flexible installation, Leitenberger offers a wide selection of connection threads:
1/4″ SAE (Standard American Screw): The most common connection size for refrigeration charging hoses and service ports.
1/8″ NPT (National Pipe Taper): A tapered thread connection that ensures excellent sealing under high pressure.
1/2″ BSP (British Standard Pipe): A straight thread connection, often used in systems with larger diameters or for fixed installations.
The bottom-mounted connector, made of brass, guarantees a solid and reliable mechanical connection to the system.
Leitenberger MG6H/MG8H/MG1H series pressure gauges are synonymous with reliability, accuracy, and durability in the field of refrigeration and air conditioning measurements. The stainless steel housing, glycerine damping, and color-coded scale optimized for refrigerants make these instruments indispensable tools during professional maintenance. The various thread types ensure that the instrument can be easily integrated into any existing or new system.
