Description
Reliable automatic compensators guarantee stability and accuracy in the line of sight. The telescope optics are bright and clear – providing a quality image. The short focusing distance allows more precise measurements in areas with steep slopes. In addition, angle measurements are extremely fast and convenient with the horizontal scale below the eyepiece.
Hardened metal makes the instruments extremely long-lasting and durable. Weather-resistant housings ensure accurate instrument operation even in unfavorable environmental conditions.
Distance measurement
With a Spectra Precision optical/automatic level you can measure the distance from the instrument axis to the rod.
Calculation example:
If the upper stadia hair reading is 1410 and the lower is 1335, the distance to the rod is 7.5 meters. How it is obtained:
| Upper hair reading | 1410 | mm |
| Lower hair reading | 1335 | mm |
| Height difference | 0075 | mm |
| Konstanta | 100 | |
| Product of the height difference and the constant | 7500 | mm |
| Atstumas | 7,5 | m |
