Our Services
Professional calibration services and precision testing equipment supply for South African industry, construction and research sectors.
Access Calibration Services provides two core offerings: professional calibration services for your existing test and measurement instruments, and the supply of new and reconditioned laboratory equipment. All calibration work produces metrologically traceable certificates referenced to national standards maintained by NMISA.
CALIBRATION SERVICES
What We Calibrate
Our calibration technicians work to recognised South African and international standards, providing traceable measurement results with full documentation of uncertainty.
Load Cells
Crane Scale · Tension · Compression
We calibrate all types of load cells including crane scales, tension load cells and compression load cells. Calibration is performed in accordance with ISO 376 and OIML R 60 standards. Our calibration certificates document the applied forces, measured values, deviations and expanded measurement uncertainty.
- Crane scale load cells
- Tension load cells
- Compression load cells
- Multi-range load cells
- Load cell indicators and displays
Compression Testing Machines
Cube Press · CBR · Pipe Tester · Culvert · Manhole
Compression testing machines used in civil and geotechnical laboratories require regular calibration to maintain accuracy in concrete strength and material testing. We calibrate machines in accordance with ISO 7500-1, covering the full range of capacities from small CBR presses to large-capacity cube presses.
- Cube press machines (concrete strength testing)
- CBR (California Bearing Ratio) presses
- Pipe testing machines
- Culvert testing equipment
- Manhole testing equipment
- Hydraulic and electro-mechanical presses
Tensile Testing Machines
Universal Testing Machines
Universal tensile testing machines (UTMs) and dedicated tensile testers are calibrated to ISO 7500-1 standards. Our calibration covers the complete force measurement system including load cells, frames, grips and indicators, ensuring your tensile test results are accurate and auditable.
- Universal testing machines (UTM)
- Dedicated tensile testers
- Wire and cable tensile machines
- Fabric and textile tensile testers
- Digital and analogue force indicators
Scales & Balances
Analytical · Precision · Industrial
Accurate weighing is critical in laboratory, production and quality control environments. We calibrate analytical balances, precision balances and industrial scales in accordance with OIML R 76 and SANS standards, using certified reference weights traceable to national mass standards.
- Analytical and precision balances
- Industrial platform and bench scales
- Hanging and crane scales (dead weight)
- Counting scales
- Moisture analysers and mass comparators
Ovens
Drying · Curing · Conditioning Ovens
Laboratory ovens used for material drying, curing and conditioning require temperature calibration to ensure uniformity and accuracy across the working chamber. We calibrate oven temperature controllers and recorders against SANAS-traceable reference standards.
- Drying ovens (soil, aggregate, material testing)
- Curing ovens
- Conditioning chambers
- Temperature controllers and recorders
- Multi-point temperature mapping
Water Baths
Temperature-Controlled Water Baths
Water baths used in concrete curing, bitumen testing and biological applications are calibrated for temperature accuracy and uniformity. We verify set-point accuracy and temperature distribution across the bath volume to ensure consistent, reproducible results.
- Concrete curing water baths
- Bitumen and asphalt water baths
- General laboratory water baths
- Temperature uniformity mapping
- Digital temperature controllers and indicators
