What ICL Calibration Laboratories does

ICL Calibration Laboratories, Inc. is a privately held, A2LA-accredited metrology laboratory headquartered in Stuart, Florida, specializing in NIST-traceable calibration of precision measurement instruments. The company serves laboratories, petroleum testing facilities, and industrial clients requiring traceable calibration for temperature sensors (ASTM thermometers, PRTs, RTDs, digital thermometers from -196 to 1000°C), hydrometers, mass/weights (1 mg to 5 kg), and volumetric glassware (0.1 ml to 3,000 ml). Its accreditation to ISO/IEC 17025-2017 covers these five disciplines, with calibration certificates recognized by ISO 9000, QS 9000, FDA, EPA, and other regulatory frameworks.

The laboratory operates precision equipment including Mettler and Sartorius mass comparators resolving to 0.1 micrograms, Hart Scientific temperature standards, and PolyScience calibration baths with ±0.005°C stability, supported by environmental controls (HEPA filtration, vibration elimination, controlled humidity and pressure for buoyancy corrections). Mass calibrations follow the NIST SOP-5 procedure requiring 12 weighings per weight. ICL is also a factory-authorized service and calibration facility for ThermoProbe and MMC electronic gauging equipment, with exclusive territorial rights covering Florida, Georgia, Puerto Rico, and the Caribbean.

Revenue is generated through two streams: (1) professional calibration services billed on a quote-based, pay-as-you-go basis with 5-8 working day standard turnaround, and (2) hardware sales of calibrated and non-calibrated instruments via direct sales, the shop.iclcalibration.com e-commerce storefront, and Amazon Marketplace. The company maintains product supply partnerships with Ludwig Schneider (non-mercury thermohydrometers), Cannon Instrument Company (viscosity standards), PolyScience (calibration baths), and others. Customer segments are vertically oriented, with petroleum/energy (custody transfer, API Chapter 7 compliance) and laboratory/research as primary, and industrial manufacturing as secondary. Go-to-market is sales-led via phone, email, and direct customer service, with no disclosed digital marketing or outbound sales motion.

Recent moves1 record

Expansion highlights4 records

Broad incumbents

• Transcat: Publicly traded US provider of calibration services and distributed products for test and measurement instruments. Comparable as a direct US-based calibration services competitor, but with much broader geographic footprint, multi-discipline capabilities, and a products distribution business that ICL does not operate.
• Mesa Laboratories: Publicly traded provider of calibration instruments and validation services for pharmaceutical, medical, and industrial customers. Comparable as a player in the calibration ecosystem serving regulated industries, though Mesa focuses more on instrument manufacturing and validation services than the laboratory calibration work ICL performs.
• Trescal: Global calibration services provider backed by private equity, operating across multiple countries with multi-discipline accredited calibration. Directly competes in calibration services for industrial/laboratory clients, though at significantly larger scale and broader scope than ICL's petroleum/laboratory niche.
• Simco Electronics: US-based accredited calibration laboratory providing commercial and military calibration services. Comparable as an accredited calibration services competitor, though with a broader multi-discipline portfolio and significant presence in defense and aerospace calibration.
• Fluke Calibration: Division of Fortive that manufactures calibration instruments including temperature, pressure, and electrical calibration sources. Comparable as a participant in the calibration ecosystem serving the same end customers, but as an instrument manufacturer rather than a calibration service laboratory.

Others

• ThermoProbe: Manufacturer of electronic tank gauging thermometers and ICL's factory-authorized service partner for Florida, Georgia, Puerto Rico, and the Caribbean. Comparable in the petroleum tank gauging instrumentation space, though positioned upstream as the manufacturer whose products ICL calibrates, repairs, and resells.
• PolyScience: Manufacturer of calibration baths and ICL's product supply partner. Comparable in temperature calibration workflows, but PolyScience supplies the bath equipment that ICL modifies and sells into petroleum PET thermometer verification applications.

Regional players

• JM Test Systems: US Gulf Coast-based calibration and testing services provider serving industrial, petrochemical, and oil & gas clients. Comparable in serving petroleum-adjacent calibration customers in the Gulf region, though with broader industrial focus and multiple locations rather than ICL's single Florida site.

Direct peers

• Cannon Instrument Company: Manufacturer of viscosity standards and viscometers, and ICL's product supply partner. Highly comparable in the petroleum testing value chain, both serving ASTM-compliant measurement workflows with NIST-traceable calibration, though Cannon is the upstream reference standards manufacturer while ICL is the calibration service provider and reseller.
• InnoCal: US-based ISO/IEC 17025 accredited calibration laboratory providing on-site and in-lab calibration services for industrial clients. Directly comparable as a competing accredited calibration laboratory with similar service offerings and customer segments, though broader in scope and geography.
