Comprehensive Calibration Services Across Any Industry
Mass Calibration
Your balances are only as accurate as the weights used to calibrate them—that’s why we maintain ASTM Class 000 mass standards with documented uncertainties traceable to NIST [1]. We calibrate test weights, weight sets, and calibration weights from 1 mg precision standards to 10 kg industrial weights, plus counting scales, precision scales, and load cells used in manufacturing, warehousing, and quality control operations. We ensure the foundation of your measurement traceability chain meets the tightest tolerances auditors expect. Explore our mass calibration capabilities →
Balance Calibration
Pharmaceutical formulation and analytical testing depend on balances measuring accurately from micrograms to kilograms. We calibrate analytical balances including microbalances, semi-micro balances, and top-loaders across 1 mg to 10 kg, with comprehensive linearity, repeatability, and corner load testing. Field calibration minimizes downtime while our laboratory handles instruments requiring tightest uncertainties. Learn more about our balance calibration services →
Electronics Calibration Services
When process control systems, data acquisition equipment, and quality testing rely on electrical measurements, out-of-tolerance multimeters and calibrators create cascading failures across your operation. We calibrate multimeters, power supplies, oscilloscopes, clamp meters, process calibrators, decade boxes, and resistance standards across voltage, current, resistance, capacitance, and frequency ranges—ensuring the electrical measurements that drive your facility’s critical decisions remain accurate and defensible.

Medical Equipment Calibration Services
Patient safety and diagnostic accuracy in healthcare facilities depend on calibrated medical devices and laboratory equipment that meet stringent regulatory and accreditation standards. We calibrate centrifuges and other laboratory equipment, patient monitoring devices, and other specialized testing instruments used in hospital laboratories, pharmacy operations, and medical device manufacturing. Our ISO 17025 accredited calibration services provide the documented traceability that regulatory inspections require. Learn about our medical equipment calibration →
Volumetric Calibration
Pharmaceutical compounding errors and invalid lab test results often trace back to one overlooked source: uncalibrated pipettes and volumetric equipment. We provide ISO 17025 accredited calibration for pipettes (0.1 µL to 10 mL) and burettes (up to 1 L) using gravimetric methods that meet ISO 8655 standards—with certificates that include the complete uncertainty statements your validation protocols demand [2].

Dimensional Calibration
When manufacturing tolerances are measured in thousandths of an inch, your calipers, micrometers, and gage blocks can’t drift—even slightly. Our temperature-controlled laboratory provides ISO 17025 accredited calibration for dimensional measurement tools up to 12 inches, using NIST traceable gage blocks to deliver the measurement certainty and documentation your quality system requires. See our dimensional calibration scope →
Temperature Calibration Services
From thermometer calibration ensuring accurate patient readings to freezer calibration protecting vaccine stability and melt flow indexer calibration controlling polymer quality—temperature measurement failures create product losses, compliance violations, and safety risks across industries. We calibrate thermometers, thermocouples, refrigerators, freezers, ultra-low freezers, ovens, furnaces, environmental chambers, and melt flow indexers across our accredited range. Discover our temperature calibration services →
Pressure Calibration
Process safety and product quality in petrochemical plants, refineries, and manufacturing facilities depend on pressure measurements you can trust. We calibrate pressure instrumentation from sensitive barometric pressure (600-1100 hPa) to high-pressure applications—using deadweight testers and precision standards that provide the accuracy your process control, safety systems, and quality assurance programs require. Review our pressure calibration services →
Torque Calibration Services
Over-torqued fasteners fail catastrophically in aerospace assemblies, while under-torqued connections in automotive manufacturing create warranty claims and safety recalls—making torque calibration non-negotiable for critical assembly operations. We calibrate torque wrenches, torque multipliers, and torque transducers that provide the documented accuracy aerospace, automotive, and manufacturing quality systems demand. Get details on torque calibration →
Vacuum Calibration
Freeze dryers, lyophilizers, and vacuum distillation systems in pharmaceutical and biotech facilities require precise vacuum control—but the vacuum gauges and measurement instruments in these systems often get overlooked until process validation fails. Our vacuum calibration services cover vacuum gauges and pressure measurement equipment from atmospheric pressure down to -30 inHg, providing the documented traceability that process validation protocols and stability study SOPs require.

How Our Calibration Services Ensure Regulatory Compliance
Our ISO 17025 accredited calibration services follow strict protocols that satisfy FDA 21 CFR Part 11, ISO 9001, GMP, and other requirements across pharmaceutical, biotechnology, and chemical manufacturing facilities.
As-Found and As-Left Documentation Our ISO 17025 accredited calibration service begins with as-found measurements using NIST traceable reference standards before any adjustments. This baseline data shows auditors whether your equipment was in tolerance since the last calibration cycle—the question every FDA inspector asks. After calibration, we document as-left values proving the equipment now meets required specifications.
Certificates That Satisfy Auditors Our calibration services provide certificates that include complete measurement data with NIST traceability statements, environmental conditions, and documented uncertainty calculations when necessary. This documentation demonstrates an unbroken chain of comparisons to national standards—exactly what regulatory audits require.
Quality System Documentation for FDA-Regulated Facilities For pharmaceutical and biotech facilities, our accredited calibration services maintain the documentation that supports regulatory inspections: calibration certificates with complete traceability, technician qualification records, equipment maintenance logs, and calibration procedures. Our electronic records system ensures secure storage and retrieval of all calibration data, providing the audit trail documentation your compliance program requires.

Your Most Asked Questions About Calibration Services
Calibration frequency depends on manufacturer recommendations, regulatory requirements, and equipment usage. Calibration frequency depends on manufacturer recommendations, regulatory requirements, and equipment usage—decisions your quality system must make and document. In our experience serving pharmaceutical and chemical facilities, instruments are commonly calibrated annually, though high-use equipment may require more frequent calibration.
Failed equipment must be immediately removed from service. You’ll need recalibration, root cause investigation, and documentation showing whether previous test results remain valid. Our 48-hour expedited calibration services provide detailed as-found/as-left data that helps determine if out-of-tolerance readings invalidate previous measurements, minimizing the scope of data revalidation required.
We can provide both on-site field calibration and laboratory calibration services under our ISO 17025 accreditation. Field service brings NIST traceable standards to your facility for equipment that cannot be moved, while laboratory calibration offers controlled conditions for complex instruments requiring specialized testing. Expedited service is also available to minimize downtime during audit preparation or equipment failures.
