SECO 2002-00 Tribrach Adjuster with 2-Minute Bubble

Overview

The SECO 2002-00 Tribrach Adjuster is a precision service tool designed for checking and adjusting optical-plummet tribrachs and tribrach bubbles.

Machined from black anodized aluminum, the adjuster provides a stable reference platform for routine calibration and maintenance. Its integrated 2-minute bubble helps technicians verify level while inspecting or correcting compatible tribrach assemblies.

The SECO 2002-00 is well suited for survey equipment shops, calibration departments, and companies that maintain their own total station, theodolite, and GNSS mounting equipment.

Optical-Plummet Tribrach Adjustment

The SECO 2002-00 can be used when checking and adjusting the optical plummet in a compatible tribrach.

An accurately adjusted optical plummet helps the operator position a surveying instrument directly over a control point, monument, nail, or other reference mark. The adjuster provides a stable platform for identifying and correcting optical-plummet alignment errors.

Tribrach Bubble Adjustment

The tool can also be used to inspect and adjust the circular bubble on a compatible tribrach.

A properly calibrated tribrach bubble provides a reliable preliminary leveling reference during instrument setup. Routine inspection helps identify bubbles that have shifted through impact, wear, transportation, or regular field use.

Integrated 2-Minute Bubble

The SECO 2002-00 features an integrated 2-minute bubble that provides a precise leveling reference during the adjustment process.

This sensitive bubble helps the technician establish a consistent level position before checking the tribrach’s optical plummet or circular vial.

Machined Aluminum Construction

The adjuster is machined from aluminum for strength, stability, and precision.

Its black anodized finish adds corrosion and wear resistance, helping protect the tool during repeated use in repair shops, calibration rooms, and survey equipment departments.

Why Tribrach Calibration Matters

A tribrach that is out of adjustment can introduce positioning and setup errors before the instrument begins measuring.

Routine tribrach inspection can help identify:

• Optical plummets that do not point directly below the instrument axis
• Circular bubbles that indicate level incorrectly
• Alignment changes caused by impacts or transportation
• Tribrachs requiring service before returning to field use

The calibration procedure should be performed by a qualified technician using the appropriate adjustment tools and manufacturer instructions.

Ideal Applications

• Optical-plummet tribrach adjustment
• Tribrach bubble calibration
• Survey instrument maintenance
• Equipment-room inspections
• Survey repair departments
• Calibration laboratories
• Total station accessory service
• Theodolite tribrach maintenance
• Preventive equipment care
