Test Products International

What Test Products International does

Test Products International (TPI) is a privately held manufacturer of handheld test and measurement instruments, founded in 1997 and headquartered in Beaverton, Oregon, with 11-50 employees. The company builds a broad portfolio of professional-grade instruments including combustion analyzers (DC710, DC711), digital multimeters and clamp meters (285, 287), manometers and pressure gauges (605BT, 608BT), gas detection meters (SP700 CO, SP1000 CO2), airflow meters (DC580), temperature probes, and vibration analyzers (9085). Its flagship differentiator is a Bluetooth-enabled "smart device" ecosystem that pairs with the proprietary TPI View smartphone app for iOS and Android, enabling technicians to measure, display, record, and email readings from combustion, differential pressure, temperature, and indoor air quality probes. TPI also sells higher-value specialty equipment including the UltraVision Acoustic Imager (a 128-channel MEMS beamforming system priced at ~$19,900) and an aviation-specific product line (WA102 Flap Transmission Test Kit, WA2025 multimeter, WA287 clamp, WA101 wireless accelerometer, WAA9112 IR camera). Auxiliary products include software licenses (VibTrend Pro at $695), test leads, oscilloscope probes, IR printers, and the TPI-3000A universal adapter kit.

TPI operates a sales-led GTM combining direct e-commerce (testproductsintl.com with a Spanish-language option) and a network of authorized distributors and resellers surfaced via a "Where To Buy TPI Products" locator, supported by a customer portal, technical support, training webinars, and trade show participation. Revenue is generated primarily through one-time hardware sales, with a smaller, complementary one-time software license stream (e.g., VibTrend Pro). Customer segments are horizontal and span HVAC/R technicians, aviation maintenance professionals, industrial condition-based monitoring buyers, indoor air quality assessors, and educational institutions, with no individual customer concentration disclosed. The company maintains international subsidiaries and markets in the United States and Spain, but no funding rounds, M&A, leadership changes, or AI/ML capabilities are disclosed in the source material.
