What InstruTech does

InstruTech, Inc. is a privately-held designer and manufacturer of vacuum measurement and control instrumentation headquartered in Longmont, Colorado. Founded in 2002 by engineers with over three decades of vacuum gauge experience, the company develops a focused product portfolio organized into five categories: full-range vacuum gauges (IGM402 Hornet, WGM701 Wasp), ionization vacuum gauges (IGM401/IGM400 Hornet hot cathode, CCM502 Hornet cold cathode, CC605/CC606, BA600, BA601/BA602/BA603), convection and Pirani-capacitance gauges (CVM201 Super Bee, CVM211 Stinger, CVG101 Worker Bee, PCM301 Busy Bee), capacitance diaphragm gauges (CDM900 Micro Bee, VSM100 Mini Bee), and rack/panel mount controllers (B-RAX 3000 series, VGC301, AGC302). Underlying technologies span hot cathode Bayard-Alpert ionization, cold cathode inverted magnetron, convection enhanced Pirani, ceramic capacitance diaphragm sensors, and combination sensor architectures, achieving measurement ranges from 2.00E-11 Torr to 1,000 Torr. Products are manufactured in a Class 10,000 cleanroom and are ISO 9001/14001 certified, RoHS compliant, and calibrated to ISO/IEC 17025 standards traceable to NIST.

The company's commercial model is a quote-based, direct-to-customer hardware sales operation conducted primarily through its website and Request-for-Quote system, with no disclosed resellers or distributors. Pricing is not publicly listed; customers submit contact, company, and product requirement details to receive quotes, consistent with an enterprise/OEM sales motion. InstruTech explicitly positions its products as plug-compatible drop-in replacements for Granville-Phillips 354, 355, and Mini-Convectron gauges, targeting existing installed bases in semiconductor, thin film deposition (PVD/PECVD), flat panel display, analytical equipment, solar cell manufacturing, and research applications (particle physics, surface analysis, space simulation, pharmaceuticals). Multiple enterprise customers, including a vacuum furnace OEM since 2009, a semiconductor turbo/cryogenic pump rebuilder, a leak detection system manufacturer, and a space research organization, are featured on the company's testimonial page.

In April 2025, InstruTech divested its ITI-CM Contract Manufacturing Division (PCB assembly operations) to Jemba9 Technology Corporation, narrowing its operational scope to the core vacuum gauge product line. The company's privacy policy references INFICON extensively, suggesting a corporate or shared-services relationship, though no explicit parent-subsidiary structure is disclosed in the available source material. The company does not list funding rounds, investors, cap table information, or revenue figures, and operates with 11-50 employees from a single Longmont facility.

Core offering

InstruTech designs and manufactures vacuum measurement and control instrumentation, including ionization vacuum gauges (hot cathode Bayard-Alpert and cold cathode inverted magnetron), convection enhanced Pirani gauges, capacitance diaphragm gauges, vacuum pressure switches, and rack/panel mount vacuum gauge controllers. Measurement capabilities span from 2.00E-11 Torr to 1,000 Torr, with products sold as complete modules with built-in electronics or as standalone sensors requiring external controllers, primarily as plug-compatible drop-in replacements for legacy Granville-Phillips products.

Product overview

InstruTech is a Colorado-based designer and manufacturer of vacuum measurement and control instrumentation. The product portfolio includes a comprehensive range of vacuum gauges organized into five main categories: Full Range Vacuum Gauges (IGM402 Hornet, WGM701 Wasp), Ionization Vacuum Gauges (IGM401, IGM400, CCM502, CC605/CC606, BA600, BA601/BA602/BA603), Convection and Pirani-Capacitance Vacuum Gauges (CVM201 Super Bee, CVM211 Stinger, CVG101 Worker Bee, PCM301 Busy Bee), Capacitance Diaphragm Vacuum Gauges (CDM900 Micro Bee, VSM100 Mini Bee), and Rack/Panel Mount Controllers (B-RAX 3000 Series, VGC301, AGC302). The gauges utilize various technologies including hot cathode Bayard-Alpert ionization, cold cathode inverted magnetron, convection enhanced Pirani, capacitance diaphragm, and combination sensors. Measurement capabilities range from 2.00E-11 Torr to 1,000 Torr. Optional power supplies (PS101, PS301, PS401, PS501) complement the product lineup. InstruTech's philosophy emphasizes reliable, multi-functional vacuum measurement products at competitive prices with strong customer support.
