Measuring range: mechanical |
Depends on the sensitivity of the built-in bubble and the number of scale divisions. The product of precision and number of scale divisions gives the value of the measurement range after each page. The exact data are located at the respective product in the shop. |
Measuring range: electronic |
+/- 15 degrees at all MICROLEVEL models |

Fixed installation and adjustability |
Roeckle guarantees consistent sensitivity through tension-free installation of the bubble. This eliminates time-consuming readjustments and calibrations before measuring. |
Casing |
Roeckle precision spirit levels according to DIN 877 have a sturdy design made of high-quality special cast iron, textured. Available depending on the model in lengths of 60, 90, 100, 120, 150, 160, 200, 250, 300, 500 mm. The existing full heat protection around the entire housing prevents influences from hand and breath heat. Housing recesses allow lateral reading of the dragonfly. |
Measuring surfaces |
With prismatic (150 °) and flat sole, for aligning horizontal surfaces and waves. All measuring surfaces are finely ground. Versions are also available with flat sole, with magnetic inserts or with holes for fixing screws. Customized designs (other angles) are possible at any time. |
Sensitivity |
The devices are equipped with polished and split longitudinal spirit level and transverse level. Available depending on model and length in the sensitivities 0.6, 0.3, 0.1, 0.04, 0.02, 0.01 mm / m. The scale value of the longitudinal level is indicated on the nameplate. The permissible deviations are very different according to DIN 877 depending on the sensitivity. |

|
Operating instruction and appropriate treatment of Precision Levels: |
1. The measurement device is highly sensitive and must be protected against humidity, cold and heat. The working temperature of mechanical Precision Levels is 20°C (+/-5 K), the storage temperature is from -40°C to +70°C. |
Checking the inclination, e.g. of a machine, by an 180° turn of the precision spirit level |
Slide the level on a clean, plane and smooth horizontal surface. The negative range is on the left of both index lines, the positive range is on the right. The position of the static bubble is the value A1 and A2 (in scale parts Scp) on the scale. Turn the level through 180 degrees, slide it to the same position of the surface. The values B1 and B2 will be added to A1 and A2 then devided by 4. The result is the inclination (A1+A2+B1+B2)/4 in Scp. (For A1 it has to be read the difference from the right bubble end to the right zero line, for A2 on the left side. For B1 and B2 it will be read after turning with the same method. The algebraic sign must be observed. |
Checking the zero-point deviation of precision spirit levels by an 180° turn (self-testing of the spirit level) |
Slide the level on a clean, plane and smooth horizontal surface (We recommend a measuring plate, Flatness Class 00). The negative range is on the left of both index lines, the positive range is on the right. The position of the static bubble is the first indicated value A (in scale parts Scp) on the scale. Turn the level through 180 degrees, slide it to the same position of the surface. Read the second indicated value B. Subtract value B from value A then devide by 2. The result is the zero point deviation DoE = (A-B)/2. Each test result is to be read on the equal index line (e.g. on the right). The algebraic sign must be observed. |
All models can be supplied with measurement protocol (certificate) at extra cost.
