How to Clean and Maintain a Monitoring Prism Malaysia
How to Clean and Maintain a Monitoring Prism Malaysia
A monitoring prism is designed to provide highly accurate and repeatable measurements for deformation monitoring, structural monitoring, and engineering surveys. However, dust, dirt, moisture, and poor maintenance can gradually reduce measurement quality and shorten the prism's service life.
Regular cleaning and proper maintenance help ensure your monitoring prism continues to deliver reliable performance for many years.
At MTM Precision Sdn Bhd, we supply professional Monitoring Prisms and surveying accessories, while also providing technical advice on proper prism care and maintenance throughout Malaysia.
Why Is Prism Maintenance Important?
Monitoring prisms are often installed outdoors for months or even years.
They are exposed to:
Heavy rain
High humidity
UV sunlight
Dust
Cement particles
Mud
Salt air (coastal areas)
Construction debris
Without regular maintenance, these conditions may reduce reflection quality and affect surveying performance.
Step 1 – Inspect the Prism Regularly
Before every monitoring survey, inspect the prism carefully.
Check for:
Dirt on the prism surface
Water stains
Cracks
Scratches
Loose mounting brackets
Corrosion on metal parts
Missing bolts
Early inspection helps prevent unexpected measurement errors.
Step 2 – Clean the Prism Surface Properly
Use only soft cleaning materials.
Recommended:
Microfiber cloth
Camera lens cleaning cloth
Lens cleaning solution
Clean water (if necessary)
Avoid:
Sandpaper
Steel wool
Hard brushes
Strong chemical solvents
Sharp metal tools
The reflective surface should never be scratched.
Step 3 – Remove Dust Carefully
If the prism is dusty:
Blow away loose dust first.
Wipe gently using a clean microfiber cloth.
Do not rub dry sand or cement particles directly across the prism surface.
This helps prevent fine scratches.
Step 4 – Check the Mounting System
The mounting bracket is just as important as the prism itself.
Inspect:
Mounting bolts
Anchor screws
L-Bar brackets
U-Bar brackets
Right-angle brackets
Ensure everything remains firmly secured.
Loose brackets may produce false deformation readings.
Step 5 – Keep the Survey Line Clear
Objects blocking the Total Station's line of sight can reduce measurement quality.
Remove or trim:
Tree branches
Tall grass
Construction materials
Temporary fencing
Equipment parked in front of the prism
A clear line of sight ensures stronger signal reflection.
Step 6 – Replace Damaged Components
Replace the prism immediately if you notice:
Chipped prism edges
Cracked glass
Broken brackets
Bent mounting hardware
Severe corrosion
Continuing to use a damaged prism may reduce measurement accuracy.

Regular maintenance helps ensure long-term monitoring reliability.
Common Maintenance Mistakes
Avoid these common mistakes:
鉂 Cleaning with rough cloths
鉂 Using abrasive cleaners
鉂 Ignoring loose brackets
鉂 Leaving cement or paint on the prism
鉂 Touching the reflective surface with dirty hands
鉂 Waiting until measurements become inaccurate before inspecting the prism
Preventive maintenance is always more effective than corrective maintenance.
