• Length: 215 mm – compact enough to handle comfortably while still offering robust performance.
• Maximum Working Range: up to 100 m – ideal for surveying large areas such as foundations, roadworks, and construction sites.
• Operating Temperature: -10 °C to +50 °C – ensures reliable operation in diverse environmental conditions.
• Storage Temperature: -20 °C to +70 °C – protects the instrument during transport or storage.
• Unit of Measurement: 360° – full circular view for comprehensive level assessment.

Design and Build Quality

The GOL 26 D features a durable metal housing that safeguards the internal optics against impact, dust, and moisture. Its robust construction is complemented by an IP54 rating, which offers protection against splashing water and limited ingress of solid particles. This makes the level suitable for use in challenging field conditions without compromising performance.

Optical Performance

At 26× magnification, the optical system delivers a sharp, high‑contrast image of the levelling line. The 360° viewing angle allows users to observe the entire circle of the level in one glance, facilitating quick checks and adjustments. This wide field of view is particularly advantageous when working on large-scale projects where multiple reference points must be monitored simultaneously.

Precision and Accuracy

The instrument’s design ensures a high degree of accuracy over its full range. The optical system is calibrated to maintain consistent alignment across distances up to 100 m, making it reliable for tasks that require exact measurements such as foundation laying, slab leveling, and structural alignment.
