What Alicat Scientific does

Alicat Scientific, Inc., founded in 1991 and headquartered in Tucson, Arizona, designs and manufactures precision mass flow and pressure measurement and control instruments for gas and liquid applications spanning research, industrial, and hazardous-location environments. Its core technology is based on laminar differential pressure (DP) mass flow measurement, complemented by three additional technology platforms: CODA Coriolis for fluid-independent high-accuracy mass flow, BASIS MEMS-thermal for compact OEM integration, and IS-Max/IS-Pro intrinsically safe variants for explosive atmospheres. Differentiated performance specifications include NIST-traceable accuracy of ±0.5% of reading or ±0.1% full scale, 10,000:1 turndown ratio, response times as fast as 30 ms, and Gas Select support for 130+ pre-calibrated gases without recalibration.

Revenue is generated primarily through hardware sales of flow and pressure instruments (mass flow meters and controllers, pressure controllers and transducers, vacuum and OEM variants), supplemented by custom OEM engineering services, calibration, repair, and accessory sales. Alicat operates a build-to-order manufacturing model anchored by its FastTrack program, shipping custom-configured instruments in 3-5 business days and standard orders in 10-15 business days. Pricing is quote-based and not publicly disclosed. Distribution combines direct enterprise sales from the US headquarters, regional offices in Shanghai (China and Asia), Duiven (Netherlands, covering 30+ European countries), Thane, and Surat (India), and a global authorized-representative network spanning Africa, Asia, Australasia, Canada, Central and South America, and additional European markets. Vertical segments include aerospace and defense, biopharmaceuticals, oil and gas, hydrogen energy, semiconductor fabrication, lab-grown diamond synthesis, environmental monitoring, food and beverage, gas chromatography, thin-film deposition, and academic and industrial research.

The company is a wholly owned subsidiary of Halma plc, a London-listed safety and environmental technology conglomerate, and operates Alicat Scientific India Pvt. Ltd. as a regional entity. Its instruments are cited in more than 1,000 peer-reviewed research publications, and the company holds ISO/IEC-style quality and hazardous-location certifications from cDEKRAus, ATEX, and IECEx. Notable proof points include the industry's first mass flow controller achieving both C1D1 and Zone 0 intrinsically safe certification, IO-Link protocol integration across the product family, and a vertically integrated Tucson manufacturing facility capable of high-mix custom production with communication-protocol coverage spanning RS-232/485, Modbus RTU/TCP, EtherNet/IP, EtherCAT, PROFINET, and PROFIBUS.
