This detailed product description presents the Leitenberger thermometer, part number MRT 02.31, equipped with bimetallic compensation and designed for front panel mounting, characterized by excellent quality German engineering (Quality made in Germany). This device is an ideal choice for industrial and commercial applications where precise temperature measurement is required and the instrument needs to be integrated into a panel or housing.
The type 02.31 thermometer is a robustly designed, bimetallic operating instrument specifically designed for front panel mounting, equipped with a 3-hole mounting flange (front plate). The stainless steel (INOX) casing and front plate guarantee a long service life and excellent resistance to corrosion, even in harsher industrial environments. Bimetallic compensation ensures accurate measurement against ambient temperature fluctuations.
This model is a combination of precision and reliability, ideal for refrigeration, air conditioning, and general industrial measurement tasks.

Note: The letters in the table denote different dimensions of the instrument on the drawings (e.g., D: Casing Diameter, L: Total Length).
In addition to the standard design, the type 02.31 thermometer can be expanded with several optional accessories and customization possibilities to satisfy the most diverse engineering requirements:
Back Adjustment: Allows the thermometer to be calibrated or fine-tuned via the back of the instrument.
Increased Accuracy: Default ± 2 selectable instead of % ± 1 % vagy ± 1.5 % accuracy also for even more critical measurements.
Drag Pointer: An accessory indicator that records the maximum or minimum measured value, helping to identify trends and peak values.
Custom Scale and Dial: It is possible to design custom dials, including colored scales or special markings.
Glass: A real glass front panel is also available as an alternative to the standard acrylic glass.
Glycerine Filling: Filling the instrument housing with glycerin significantly dampens the needle's vibration, enabling a more stable reading in heavily vibrating systems.
For accurate measurement and professional installation, Leitenberger offers a wide selection of sensors and fittings compatible with the thermometer. These accessories ensure the optimal connection of the thermometer to the system being tested.
Capillaries that ensure the connection between the thermometer and the temperature sensor (probe) are available in different materials and designs:
Stainless Steel (Naked): Natural stainless steel capillaries.
Copper – Single Copper Braided: Copper capillary with copper braided shielding.
Copper – Double Copper Braided: Copper capillary with greater mechanical protection.
Copper – PVC Coated (Cu-PVC coated): Copper capillary equipped with a PVC outer coating, which provides additional protection against moisture and chemical effects.
Probe types that influence measurement accuracy and installation method:
Type 1 (Type 1a, b, c): Probes with different designs.
Type 2 (Type 2a, b, c): Further variations regarding installation depth and design.
Type 3 (Type 3a, b, c): Special probe designs.
Type 4 (Type 4a, b,c): Fourth probe family.
Type 5 (Typ 5a, b, c): Fifth probe family.
Type 6 (Typ 6a): Sixth probe type.
Type 7c (Typ 7c): Probe with special design.
Type 7.1 (Typ 7.1): Custom probe variant.
Protective sleeves for thermometer protection and simple removal and installation from the system:
Type 8 (No. 8): Standard protective sheath.
Type 9 (No. 9): Protective sheath with alternative size or design.
The Leitenberger Type 02.31 thermometer is ideally applicable in the following areas:
Refrigeration technology: Pressure and temperature monitoring of cooling units and climate control systems.
Industrial Measuring Technology: General process monitoring where a stable, analog display is required.
Industrial Testing Technology: Temperature monitoring of test benches and equipment.
Solar Collector Systems: Reliable monitoring of the temperature of solar systems (when supplemented with the appropriate probe).
This stainless steel front-mounted thermometer reflects Leitenberger's commitment to precise, durable, and reliable measuring instruments manufactured in Germany.
