What AccuTru International does
AccuTru International, founded in 1999 and headquartered in Kingwood, Texas, is a privately held custom thermocouple and Resistance Temperature Device (RTD) manufacturer serving industrial temperature-measurement applications across North America. The company's product portfolio is anchored by its proprietary MI-Dry mineral insulation compound — a registered dielectric ceramic insulant with the same MSDS profile as Magnesium Oxide (MgO) but engineered to eliminate Green Rot corrosion, moisture absorption, and virtual junction errors — and by HD247 high-density alumina protection tubes for high-temperature service. Core offerings include ExL thermocouples (drop-in replacements for existing MgO sensors with no wiring changes), high-temperature thermocouples for environments above 2300°F (S, R, B, and W/C/D/G types), tube skin thermocouples, custom platinum-element RTDs, thermowells, and the SVS-III self-validating sensor system featuring HART Protocol, explosion-proof housing, and on-board self-validation/self-diagnostics — claimed by the company as the only self-validating temperature measurement system in the marketplace.
The company also manufactures special-application sensors, including Scavenge Oil Temperature Test Kits for JT8D-200/MD80 aircraft engines, ionization flame probes, and custom units for dairy and plastic processing. AccuTru operates a sales-led, quote-based direct sales model with no publicly disclosed pricing and multi-year contract terms; products are configured to customer specifications without intermediaries. Its customer base spans refineries, aircraft manufacturers, national laboratories and universities, nuclear testing facilities, chemical and petrochemical processors, heat treating and industrial processing operations, and pharmaceutical manufacturers — concentrated geographically across the U.S. Gulf Coast, West Coast, Midwest, and Canada.
Revenue mechanics are entirely hardware sales on custom-build orders, with no software, subscription, or recurring service line documented. The firm employs 11-50 people, is privately held with no disclosed institutional investors, parent company, subsidiaries, funding rounds, M&A activity, or leadership changes in the available record. The operating posture is that of a stable, founder/owner-operated specialty manufacturer with 27 years of compounding materials-science know-how and process-control application expertise.

Products and services
- ExL Thermocouples High temperature thermocouples insulated with AccuTru's proprietary MI-Dry ceramic insulation material, providing superior performance to standard Magnesium Oxide (MgO) insulation. Drop-in replacements for existing MgO sensors with no wiring changes required. Designed for industrial process control customers needing longer sensor life and lower maintenance costs.
- High Temperature Thermocouples Thermocouples designed for high temperature applications above 2300°F, built using ceramic or metal-ceramic protection tubes and platinum thermoelement wires (S, R, B designations) for oxidizing environments, or Tungsten/Rhenium types (W, C, D, G designations) for reducing environments. Used in heat treating, incinerators, glass melters, and similar industrial high-temperature applications.
- Tube Skin Thermocouples Thermocouples fabricated with ExL technology and MI-Dry mineral insulation that reduce or eliminate virtual junction errors (VJE), providing true temperature readings at the sensor tip. Available with various weld pads and custom heat shields for tube surface temperature measurement in refining and process applications.
- Custom RTDs (Resistance Temperature Devices) Customized resistance temperature devices using platinum elements for temperature measurement from ambient to 600–700°C (1112–1282°F). Manufactured with MI-Dry mineral insulation for improved performance and longer life, using wire wound bulbs meeting IEC751 tolerances. Offers tighter accuracy (0.3 or 0.7°C at 100°C) than thermocouples (1.1°C) for industrial customers needing higher precision.
- Thermowells Protective wells for temperature sensors enabling rapid delivery for most items, used to shield thermocouples and RTDs in industrial process installations.
- SVS-III Self-Validating Sensor System The only self-validating temperature measurement system in the marketplace, featuring HART Protocol support, explosion proof housing, and self-validation/diagnostics capabilities. Priced competitively with other premium transmitters while providing additional benefits of self-validation for temperature-critical applications in chemicals/petrochemicals, heat treating, refining, gas turbines, safety interlocks, incinerators, pharmaceuticals, and glass melters.
