What APEX Instruments does
APEX Instruments, Inc. is a privately held industrial measurement equipment distributor and calibration services company headquartered at 7200 East Dry Creek Road in Centennial, Colorado. Founded in 1998 and operating continuously for over 25 years, the company serves U.S. oil and gas industry operators and service companies requiring pressure, temperature, and process instrumentation. It operates a single domestic office with 11-50 employees and runs direct enterprise field sales supported by technical expertise, with quotes and calibration orders handled through its website and phone channel at (303) 804-0667.
The company's core technology is its ANAB ISO/IEC 17025 accredited calibration laboratory, which delivers NIST traceable calibrations for customer-owned instruments covering pressure and temperature references. This credentialed laboratory underpins the recurring services revenue and is a hard prerequisite for compliance-driven calibration work in upstream, midstream, and downstream oil and gas operations. Beyond the lab, APEX functions as an authorized distributor and manufacturer representative for more than 15 industrial measurement brands, including Emerson/Rosemount (Rosemount Measurement Solutions, Rosemount Tank Gauge, MicroMotion, AMS Trex), Ametek (Crystal Pressure, Jofra Temperature), Fluke, Additel, Ralston, PIE, Thermoprobe, Strahman, Reotemp, Rexa, Drager, Siemens, Perma-Cal, and Kelley. Its product surface includes three engineered field calibration bundles — the New Tech Starter Bundle, the Pro Calibration & Diagnostics Bundle, and the Complete Process Calibration Bundle — that combine instruments from multiple represented manufacturers into pre-vetted kits for technicians performing commissioning, troubleshooting, and routine calibration in industrial environments.
APEX makes money through two revenue streams: (i) one-time equipment distribution on the multi-vendor line card, and (ii) fee-for-service calibration work in the in-house lab. Pricing is not publicly disclosed; customers request quotes via the company website's RFQ form or by phone. The customer base is concentrated vertically in oil and gas with no publicly named end-customer logos. Distribution is single-channel and domestic: direct enterprise field sales from Centennial, CO. The company holds ANAB ISO/IEC 17025 certification, has no disclosed institutional investor or parent-company ownership, no disclosed funding history, and no disclosed management team in the available material.

APEX Instruments competitors and assessment
Company assessmentDirect peers
- Trescal: Global accredited calibration services company operating ISO/IEC 17025 labs across multiple geographies. Comparable to APEX as a competing provider of NIST-traceable calibration services for pressure, temperature, and electrical/process instruments in oil and gas and adjacent industrial verticals.
- Transcat: U.S.-based accredited calibration services provider and distributor of test, measurement, and control instrumentation. Directly comparable to APEX because it combines ISO/IEC 17025 calibration lab services with multi-brand instrument distribution to industrial customers including oil and gas.
Emerging players
- Additel: Manufacturer of pressure calibrators, documenting process calibrators, and pneumatic/hydraulic pumps. A principal whose products APEX distributes; competes with APEX's bundle business in the sense that Additel sells direct and through other channels into the same oil and gas field-calibration buyer.
- Beamex: Manufacturer of industrial calibration equipment (pressure, temperature, multifunction calibrators) and calibration software. Comparable to APEX because its products populate APEX's bundle offerings and target the same end users performing field calibration in process industries.
- Ralston Instruments: Manufacturer of pressure calibration equipment including hand pumps (DPOV) and nitrogen supply systems (Nitro-Pak). A principal APEX represents; comparable as a focused calibration-equipment vendor targeting the same oil and gas field-technician buyer.
Broad incumbents
- Fluke Calibration: Division of Fluke Corporation manufacturing electrical, temperature, and pressure calibration instruments. Comparable because Fluke-branded products (789 ProcessMeter, 773 mA Clamp) anchor APEX's bundles, and Fluke Calibration runs its own service and accreditation programs that compete with APEX's lab.
- Endress+Hauser: Global manufacturer of industrial process measurement instruments and provider of calibration services for flow, level, pressure, temperature, and analytical parameters. Comparable to APEX because it sells overlapping instrumentation and offers accredited calibration support to oil and gas and process industry customers.
- Emerson Rosemount: Emerson's measurement instrumentation business (Rosemount, MicroMotion, AMS Trex) for pressure, temperature, flow, tank gauging, and valve diagnostics. APEX is an authorized distributor; comparable as a broad incumbent whose direct service and sales channels can substitute for APEX's distribution and calibration services.
- Ametek Calibration Instruments: Business unit of Ametek encompassing Crystal Pressure and Jofra Temperature brands for high-accuracy pressure and temperature calibration. A principal APEX represents and a broad incumbent whose own direct sales and service programs overlap with APEX's offering in oil and gas.
- Yokogawa Electric: Global supplier of industrial automation, process control, and field instrumentation including pressure and temperature transmitters. Comparable to APEX as a broad incumbent whose process instrumentation portfolio and service organization compete in the same oil and gas customer base.
