Myzox CL-28 CL-36 Auto Level for Benchmark Transfer and Elevation Measurement Malaysia
Myzox CL-28 CL-36 Auto Level for Benchmark Transfer and Elevation Measurement Malaysia
Benchmark transfer and elevation measurement are fundamental tasks in construction surveying and civil engineering. A reliable reference level allows contractors and engineers to maintain consistent elevations across different parts of a project.
The Myzox CL-28 and CL-36 Auto Levels are professional optical leveling instruments suitable for benchmark transfer, elevation checking and general construction surveying applications in Malaysia.
The CL-28 provides 28X magnification with ±2.0 mm accuracy for 1 km double-run leveling, while the CL-36 offers higher 36X magnification with ±1.0 mm accuracy.
MTM Precision Sdn. Bhd. is an authorized distributor of Myzox in Malaysia, supplying Myzox surveying instruments and accessories for professional users.
What Is a Benchmark in Construction Surveying?
A benchmark is a fixed reference point with a known or established elevation.
Construction teams can use this reference to determine the elevations of other points throughout the project site.
Benchmarks are important for work involving:
Building foundations
Finished floor levels
Road formation
Drainage
Earthworks
Infrastructure
Concrete structures
Site development
Without a consistent elevation reference, different sections of a project could potentially be constructed at incorrect levels.
What Is Benchmark Transfer?
Benchmark transfer is the process of extending or transferring a known elevation from one location to another.
For example, an established benchmark may be located near the entrance of a construction site.
As construction progresses, contractors may need additional temporary benchmarks closer to:
A building foundation
A road section
A drainage area
An excavation zone
Another part of a large development
An automatic level and leveling staff can be used to transfer the elevation from the original reference to the new location.
How Does an Auto Level Measure Elevation Differences?
The basic process involves observing staff readings from a stable instrument position.
A simplified leveling sequence may include:
Set up the Myzox Auto Level on a stable tripod.
Properly level the instrument.
Place a leveling staff on the known benchmark.
Take and record a backsight reading.
Calculate the height of instrument.
Move the staff to the required point.
Take the next reading.
Calculate the elevation of the new point.
For important engineering work, the actual field procedure should follow the project's specified surveying methodology.
Why Use Myzox CL-28 for Benchmark Transfer?
The Myzox CL-28 provides a practical specification for routine construction leveling.
Key specifications include:
28X magnification
36 mm objective aperture
0.4 m minimum focusing distance
±2.0 mm accuracy for 1 km double-run leveling
±15′ self-leveling range
360° horizontal circle
Approx. 1.3 kg weight
The CL-28 is particularly suitable for general building and civil construction where observation distances and accuracy requirements are within its specifications.
Why Use Myzox CL-36 for Benchmark Transfer?
The Myzox CL-36 offers a higher specification for users requiring greater magnification and leveling accuracy.
Key specifications include:
36X magnification
36 mm objective aperture
0.4 m minimum focusing distance
±1.0 mm accuracy for 1 km double-run leveling
±15′ self-leveling range
360° horizontal circle
Approx. 1.3 kg weight
The CL-36 can be particularly useful for larger sites and engineering projects where higher magnification is beneficial.
Applications for Elevation Measurement
The Myzox CL series can support elevation measurements across many types of projects.
Foundation Work
Check excavation, footing and foundation elevations against established reference levels.
Finished Floor Level
Transfer and verify elevation references during building construction.
Road Construction
Check formation, earthwork and related road elevations.
Drainage
Establish and verify elevations for drains, culverts and other gravity-flow infrastructure.
Earthworks
Monitor excavation and filling against project reference levels.
Infrastructure
Transfer benchmarks across larger project sites to maintain consistent elevation control.
Why Accurate Benchmark Transfer Matters
Small elevation errors can become significant when a reference is repeatedly transferred across a project.
Good surveying practice is therefore important.
Operators should consider:
Stable tripod setup
Correct instrument leveling
Vertical staff positioning
Clear telescope focusing
Appropriate observation distances
Accurate reading and recording
Suitable checking procedures
Regular instrument inspection
Critical benchmarks may also require independent verification according to the project's surveying requirements.
CL-28 or CL-36 for Elevation Measurement?
For general construction and routine benchmark transfer, the CL-28 provides a practical 28X solution.
For users who need:
Higher magnification
Greater staff visibility at longer distances
Higher specified leveling accuracy
the CL-36 may be more suitable.
The correct choice depends on the required tolerance and working conditions rather than magnification alone.
Frequently Asked Questions
Can the Myzox CL-28 transfer benchmarks?
Yes. The CL-28 can be used for general benchmark transfer and construction elevation measurement.
Is the CL-36 better for precision leveling?
The CL-36 has the higher specified leveling accuracy at ±1.0 mm for 1 km double-run leveling, compared with ±2.0 mm for the CL-28.
Can an auto level measure height directly?
An optical auto level provides staff readings that are used to determine elevation differences. The operator calculates or records the resulting elevations using an appropriate leveling method.
Can these models be used for Finished Floor Level?
Yes. Automatic levels can assist in transferring and checking elevation references associated with Finished Floor Level work.
Can they be used for road benchmarks?
Yes. The CL series can support benchmark transfer and elevation checks for road and infrastructure construction.
Which model should I choose?
Choose the CL-28 for general construction leveling or consider the CL-36 when higher magnification and greater specified accuracy are required.
