Accredited Calibration for Measurement Confidence

In mission-critical environments, reliable measurements are essential for effective decision-making. A monitoring system is only as accurate as the calibration behind it.

With more than 30 years of calibration expertise, ISOLAB Pte Ltd is an ISO/IEC 17025 accredited calibration laboratory providing internationally traceable calibration services across a wide range of environmental and process parameters. Our accredited calibration ensures measurement traceability, reduced uncertainty, and confidence that monitoring instruments perform within their specified accuracy.

Accurate calibration enables organisations to:

• Improve confidence in measurement data
• Support SS591 Green Mark compliance and regulatory requirements
• Reduce operational risks caused by inaccurate measurements
• Optimise cooling system performance and energy efficiency
• Strengthen quality assurance and maintenance programmes

Comprehensive Calibration Services for Data Centres

ISOLAB supports the complete environmental monitoring chain through accredited calibration services for:

Temperature & Humidity

High-accuracy calibration for:

• RTD sensors (Pt50, Pt100, Pt500, Pt1000)
• Green Mark temperature sensors (10 kΩ NTC thermistors)
• Thermocouples
• Temperature transmitters, controllers, indicators, and switches
• Digital thermometers and data loggers
• Infrared thermometers
• Humidity and dew point measurement systems

These services help ensure accurate environmental monitoring, cooling optimisation, and thermal management throughout the data centre.

Pressure, Airflow, Water Flow & IAQ

ISOLAB also provides accredited calibration and verification for:

• Differential pressure transmitters
• Air velocity meters and hot-wire anemometers
• Capture hood balometers
• Water flow meters
• Chilled water flow verification
• Indoor Air Quality (IAQ) instruments including CO, CO₂ and H₂ gas monitoring

Accurate calibration of these instruments enables facility operators to maintain balanced airflow, optimise chilled water systems, improve HVAC performance, and detect system inefficiencies before they impact operations.

Advanced Calibration Capabilities

To achieve the highest level of measurement confidence, ISOLAB utilises internationally recognised calibration techniques and precision reference standards.

Our capabilities include:

ITS-90 Fixed Point Calibration

Supporting the highest accuracy temperature calibration using internationally recognised fixed points, including:

• Water Triple Point (TPW)
• Gallium Melting Point
• Indium Freezing Point
• Tin Freezing Point
• Zinc Freezing Point

Comparison Calibration

Using precision liquid baths, dry block calibrators, platinum resistance thermometers (PRTs), thermocouples, and high-accuracy reference bridges to deliver reliable and traceable calibration results across a wide temperature range.

These advanced calibration methods minimise measurement uncertainty while ensuring long-term measurement stability and repeatability.

On-Site Calibration & Temperature Mapping

Removing installed monitoring equipment from service can disrupt critical operations. ISOLAB provides on-site calibration and validation services, allowing measurement systems to be verified in their actual operating environment with minimal downtime.

Our services include:

• On-site calibration of installed monitoring systems
• Temperature, humidity, pressure, airflow, and water flow verification
• Chilled water system validation
• Sensor performance verification
• Environmental monitoring system validation

ISOLAB also performs temperature mapping to identify:

• Temperature uniformity
• Hot and cold spots
• Environmental fluctuations
• Optimum sensor placement
• Compliance with IQ, OQ and PQ validation requirements

These services are widely applied across server rooms, data halls, HVAC systems, chilled water networks, cleanrooms, warehouses, and controlled environments.

Supporting Reliable and Sustainable Operations

Reliable calibration provides the trusted measurement data needed to improve operational performance and sustainability.

With accurate, traceable measurements, data centre operators can:

• Optimise cooling efficiency
• Reduce unnecessary energy consumption
• Improve chilled water performance
• Extend equipment life
• Support predictive maintenance
• Lower operating costs
• Reduce carbon emissions
• Meet ESG and sustainability objectives

Accurate calibration transforms monitoring data into actionable engineering intelligence, enabling better operational decisions throughout the lifecycle of the facility.
