Calibration Services – Keeping Your Instruments Accurate Over Time

Calibration is not a one-time event—it is an ongoing requirement for maintaining instrument accuracy and regulatory compliance. Regular calibration ensures that your hygrometers, thermometers, and timers continue to provide reliable measurements throughout their service life.

Why Professional Calibration Services Matter

Maintain Accuracy: All instruments drift over time. Regular calibration detects and corrects drift, ensuring that your instruments continue to provide accurate measurements.

Regulatory Compliance: Many regulated industries require documented calibration at specified intervals. Professional calibration services provide the documentation needed for audits.

Extend Instrument Life: Regular calibration and maintenance identify issues early, preventing costly failures and extending instrument life.

Protect Your Products: Accurate measurements protect your products from quality issues, spoilage, and regulatory violations.

Our Calibration Services

1. Factory Calibration (New Instruments)
Every instrument we manufacture is factory-calibrated before shipment. Calibration is performed against NIST-traceable reference standards. Each instrument comes with a calibration certificate documenting its performance.

2. Recalibration Services
Instruments in the field can be returned to our facility for recalibration. We perform calibration against NIST-traceable reference standards. Calibration certificates are provided for all recalibrated instruments. Instruments are adjusted if necessary to bring them within specification.

3. Calibration Verification
For customers who perform in-house calibration, we offer calibration verification services—comparing your reference standards against our NIST-traceable standards.

Calibration Process

Step 1: Receiving and Inspection
Instruments are received and inspected for physical damage. Pre-calibration readings are recorded.

Step 2: Stabilization
Instruments are allowed to stabilize at calibration conditions.

Step 3: Calibration
Instruments are tested at multiple points across their operating range against NIST-traceable reference standards. Readings are recorded and compared to specifications. Adjustments are made if necessary.

Step 4: Verification
Post-calibration readings are verified against reference standards.

Step 5: Documentation
A calibration certificate is issued documenting the instrument's performance, reference standards used, and traceability.

Step 6: Return
Instruments are returned with calibration certificate and any maintenance recommendations.

Calibration Standards We Use

• Reference hygrometers: NIST-traceable chilled-mirror hygrometers

• Reference thermometers: NIST-traceable PRTs (Platinum Resistance Thermometers)

• Calibration chambers: Temperature and humidity-controlled chambers

• Two-pressure humidity generator: For highest-accuracy calibration

Recommended Calibration Intervals

In-House Calibration vs. Professional Services

In-House Calibration:

• Advantages: Faster turnaround, lower cost per calibration, immediate availability

• Disadvantages: Requires investment in reference standards, trained personnel, controlled environment

• Best for: Organizations with many instruments or critical applications

Professional Calibration Services:

• Advantages: NIST-traceable standards, accredited procedures, documented quality

• Disadvantages: Longer turnaround, higher per-instrument cost

• Best for: Organizations requiring accredited calibration, limited in-house capability

Calibration Documentation

Our calibration certificates include:

• Instrument identification (model and serial number)

• Date of calibration

• Reference standards used and their NIST traceability

• Environmental conditions during calibration

• Before and after readings

• Uncertainty of measurement

• Signature of authorized personnel

• Next calibration due date
