# Leitenberger MB \/ MR Pressure Gauges \u2013 Precision Manometers for Refrigeration Applications<\/p>\n
The Leitenberger MB\/MR series pressure gauges are high-quality, dry-operation, pulsation-free manometers specifically designed for the reliable pressure measurement in refrigeration and air conditioning systems. The \u201eMade in Germany\u201d quality guarantees a long service life and accurate measurements even in the most demanding industrial environments.<\/p>\n
These instruments are ideal for monitoring the pressure of the refrigerant, ensuring optimal system operation and the professional execution of maintenance tasks.<\/p>\n
## Main Features and Advantages<\/p>\n
The MB\/MR series pressure gauges prioritize reliability and easy readability:<\/p>\n
* **Dry Design:** The instruments feature dry filling, which guarantees pulsation-free operation even under strongly fluctuating pressure conditions. This increases measurement accuracy and reduces wear on internal components.
\n* **Excellent Accuracy:** The 1.6 accuracy class ensures that the measured values meet strict professional requirements.
\n* **Robust Design:** The steel sheet housing withstands mechanical stress. The color of the housing indicates the measurement range:
\n* **Blue:** Low pressure
\n* **Red:** High pressure
\n* **Colored Scale for Refrigerants:** Colored markings on the scale aid in the quick and error-free identification of pressure ranges belonging to different refrigerants.
\n* **Connection Options:** The instruments feature a brass connection, available in a radial (bottom) or axial (rear) arrangement.
\n* **Standard Thread Sizes:** Two standard connection threads are available for wide compatibility: 1\/4 SAE or 1\/8 NPT.<\/p>\n
## Technical Data Summary<\/p>\n
The MB\/MR series is available in two main sizes and designs, with different diameters and connection types.<\/p>\n
