Energy Audit Instruments & Calibration Standards

Our Energy Audit Instruments & Calibration Standards

At Elion Technologies and Consulting Private Limited, our energy audits are measurement-driven and data-backed.

We use in-house, industry-grade instruments to capture accurate electrical, thermal, flow, combustion, lighting, and air system data. The use of calibrated equipment ensures that our audit findings are based on measurable evidence rather than assumptions.

Energy audits are conducted using calibrated, industry-grade instruments under supervision of certified professionals

Electrical & Power Quality Analysis

For detailed electrical performance assessment, load profiling, and power quality evaluation, we use advanced Fluke power analyzers including:

Fluke 43B
Fluke 1733
Fluke 1736
Fluke 1777
Fluke 435-II

These instruments are deployed during audits to record:

  • Load patterns and demand trends
  • Power factor and harmonic levels
  • Voltage imbalance and fluctuations
  • Energy consumption behavior
  • Distribution-level inefficiencies

Electrical logging is carried out over appropriate durations to capture real operating conditions.

Thermal Imaging & Hotspot Detection

Thermal inspections are conducted using professional-grade cameras from Testo and FLIR, including:

Testo 875-2i
Testo 875-1
FLIR T530
FLIR C2 (4 units)
FLIR C1 (7 units)

Thermography is used alongside electrical measurements to identify:

  • Overheated connections
  • Imbalanced loading
  • Transformer and panel hotspots
  • Motor and equipment stress points

This combined analysis helps in early detection of losses and risk areas.

Lighting & Lux Survey

Illumination levels are measured using:

Testo 540 (6 units)
Fluke 9410 (3 units)

These instruments are used for lux mapping across facilities. Readings are compared against applicable lighting standards and operational needs to identify improvement opportunities.

Air Flow & Ventilation Assessment

For HVAC and ventilation performance evaluation, we use:

Testo 410 (6 units)
Lutron AM4202 (2 units)

Air velocity and airflow distribution are measured to assess ventilation adequacy and energy efficiency of air handling systems.

Combustion & Flue Gas Analysis

Boiler and combustion efficiency analysis is performed using:

Testo 310
Testo 300 (2 units)

These analyzers measure combustion parameters and help evaluate efficiency, tuning requirements, and potential energy savings.

Compressed Air Leak Detection

For identifying compressed air losses, we use:

Fluke FLK-II910 Precision Acoustic Imager

This instrument helps detect and locate air leaks, which are then quantified to estimate avoidable energy loss.

Supporting Instruments

Additional instruments used during audits include:

Hygrometers from Testo, Lutron, and HTC (multiple units)
Clamp meters from Rishabh and Fluke (multiple units)
Fluke 931 Tachometer

These support electrical verification, environmental monitoring, and mechanical performance checks during audits.

Instruments are calibrated as per recommended intervals to maintain accuracy and traceability

Calibration & Measurement Integrity

All instruments used during our audits are periodically calibrated to maintain accuracy and reliability. Calibration ensures that recorded data is consistent and traceable.

Calibration certificates can be shared during project execution upon request.

Why This Matters

An energy audit without proper measurement tools becomes theoretical.

At Elion, our audits are:

  • Measurement-based
  • Instrument-verified
  • Technically structured
  • Consistent across multiple cities

This approach strengthens the credibility of our findings and supports implementable energy-saving recommendations.

Frequently Asked Questions

Why do instruments matter in an energy audit?

An energy audit is based on measurements. Without proper instruments, the findings can become assumptions. Professional tools ensure that energy usage, losses, and inefficiencies are identified using actual data, not estimates.

Are all instruments owned by Elion or outsourced?

All major instruments used during our energy audits are owned and operated in-house. This allows us to maintain control over measurement quality, scheduling, and data integrity across multiple project locations.

Are your instruments calibrated?

Yes. All instruments are periodically calibrated to maintain measurement accuracy and reliability. Calibration ensures that recorded readings are dependable and consistent across different sites.

Calibration certificates can be shared during project discussions if required.

Why do you use multiple power analyzers and thermal cameras?

Different facilities have different electrical loads and complexities. Using multiple instruments allows us to:

  • Capture readings from several panels simultaneously
  • Monitor systems over longer durations
  • Cross-verify measurements
  • Maintain consistency in multi-site projects

This improves the overall quality of the audit.

Do you only perform electrical measurements?

No. Our audits cover multiple systems including:

  • Electrical distribution
  • Power quality
  • HVAC and airflow
  • Pumps and water systems
  • Boilers and combustion systems
  • Compressed air systems
  • Lighting and lux levels

We use different instruments together to evaluate overall system performance.

Can instrument data be shared with the client?

Yes. Measurement data and supporting readings are included in the audit report. Where required, raw logs or screenshots from instruments can also be shared as part of documentation.

How does instrument quality affect audit recommendations?

Accurate instruments lead to accurate data. Accurate data leads to practical and implementable recommendations. This reduces guesswork and increases confidence in decision-making.

Do you use different instruments for different industries?

The core instruments remain the same, but their application varies depending on the industry — whether it is manufacturing, commercial buildings, hospitals, warehouses, or infrastructure projects.
