Weiss Instruments

What Weiss Instruments does

Weiss Instruments, Inc. is a US-based, privately held specialty manufacturer of thermometry (temperature measurement) instruments, in continuous operation since 1882. The company is headquartered in Holtsville, New York, and operates with a small workforce of 11-50 employees, consistent with a long-established niche industrial manufacturer rather than a venture-backed growth business. Ownership and executive leadership are concentrated in the founding family: Steve Weiss is listed as owner/founder and John Weiss as president, indicating a multi-generational, family-controlled governance structure with no outside institutional investors disclosed.

The company's core product domain — thermometry — encompasses industrial and commercial temperature measurement instruments (e.g., bimetal thermometers, gas- and liquid-filled thermometers, related instrumentation), serving process industries, HVAC, and general industrial monitoring use cases. The input data does not surface specific product SKUs, technical specifications, proprietary technology, patent portfolio, or certifications; the company's own website content captured in the scrape is a non-substantive loading/verification page. No distribution channels, pricing model, or go-to-market motion is disclosed in the available data.

On the business model side, the company is understood to generate revenue through the manufacture and sale of physical temperature measurement instruments, with the implied revenue mechanics of unit-based industrial product sales plus recurring calibration and replacement demand typical of the category. The company is private with no funding history, no M&A activity, no partnerships, and no app or digital product surface documented, reinforcing the profile of a stable, traditional industrial SMB rather than a technology-enabled platform. The overall data set is thin: most structured enrichment fields (customers, pricing, technology, headcount detail, geographic footprint beyond headquarters) are empty, and any forward-looking assessment is necessarily constrained by that gap.

Broad incumbents

• Fluke Corporation: Industrial test and measurement instrument leader with strong temperature and electrical diagnostics offerings. Comparable through industrial thermometry products, though Fluke's scope and scale are far broader than Weiss's.
• Honeywell International: Diversified industrial conglomerate with a large process-measurement and controls portfolio including temperature instruments. Overlaps with Weiss in industrial channels but spans far broader product and service categories.

Direct peers

• Ashcroft Inc. U.S. manufacturer of pressure and temperature measurement instruments for industrial process applications. Closely comparable to Weiss as a heritage U.S. industrial instrumentation brand serving overlapping OEM and end-user channels.
• Cooper-Atkins Corporation: U.S. specialist in temperature measurement for foodservice, industrial, and HVAC markets. Comparable to Weiss as a niche industrial thermometry brand with multi-channel distribution.
• Watlow Electric Manufacturing: Specialist in thermal systems and temperature sensors for industrial applications. Comparable to Weiss on thermometry depth, though Watlow is larger and more focused on heaters and integrated thermal subsystems.
• WIKA Instrument Corporation: Global leader in industrial measurement of pressure, temperature, level, and flow. WIKA is the most direct comparable to Weiss given its deep industrial thermometer portfolio and similar core customer base in process and OEM industries.
• Omega Engineering: Broad-line industrial sensor and instrumentation supplier with a particularly strong temperature-measurement catalog. Omega competes with Weiss across industrial thermometry, thermocouples, and RTDs.
• Reotemp Instrument Corporation: U.S. manufacturer of industrial thermometers and pressure gauges with strong OEM and process-industry focus. Closely comparable in size, product mix, and channel orientation to Weiss.
• Trerice (H.O. Trerice Co.): Long-standing U.S. industrial instrumentation brand producing thermometers, pressure gauges, and related measurement products. Highly comparable in heritage, niche, and customer base to Weiss Instruments.
• Weksler Glass Thermometer Corp: U.S. manufacturer of industrial and laboratory thermometers including glass, bimetal, and digital types. Direct peer given overlapping industrial thermometry product lines and customer segments.
