What Machine Applications does

Machine Applications Corporation, doing business as MAC Instruments, is a privately-held industrial instrumentation manufacturer founded in 1990 and headquartered in Sandusky, Ohio. The company designs and builds solid-state moisture analyzers and steam flow meters engineered specifically for high-temperature industrial environments where conventional humidity sensors degrade or fail. Its core product family includes the MAC125 in-situ stack gas moisture analyzer, the MAC155 portable ambient temperature analyzer, the MAC116 portable moisture analyzer, and a line of steam flow meters and transmitters. Underlying the product line is a patented solid-state humidity measurement technology that the company positions as a durable technical differentiator in the narrow high-temperature moisture sensing segment.

The business sells capital equipment to industrial end-users in power generation, food processing, paper, metals, construction materials, and agriculture. Products are explicitly designed to support EPA compliance under 40 CFR Part 60 and Part 75, making them a qualified specification for continuous emissions monitoring applications at coal-fired power plants. Go-to-market is executed through a network of authorized regional distributors covering the United States, Australia, New Zealand, India, Italy, South Korea, and China, with pricing conducted on a quote basis per project rather than published list pricing. The company is small (11–50 employees), has operated continuously for more than three decades without recorded external funding, M&A, or leadership transitions, and supplements its commercial activity with educational content such as a published Moisture Handbook and an active technical blog.

Core offering

MAC Instruments manufactures and sells industrial moisture analyzers (MAC125, MAC155, MAC116), steam flow meters, and steam flow rate transmitters designed for high-temperature industrial process measurement. The instruments use a patented solid-state humidity measurement process to provide absolute moisture readings without chemicals, compressed air, wet bulb techniques, optics, or mirrors, and support applications in power generation, emissions monitoring, food processing, paper production, and metal processing.

Product overview

Machine Applications Corporation (MAC Instruments) offers a portfolio of industrial moisture analyzers and steam flow measurement instruments for high-temperature applications. The product line includes the MAC125 and MAC155 moisture analyzers (for humidity measurement in stacks, ducts, ovens, and furnaces up to 2400°F), the MAC116 Steam Analyzer (specialized for food processing conveyor ovens), along with Steam Flow Meters and Steam Flow Rate Transmitters for accurate measurement and control of process steam. All products use proprietary solid-state sensor technology without chemicals, compressed air, or optics, providing NIST-traceable direct moisture level measurements for industries including power generation, food processing, metal processing, and paper production.

Products and services

• MAC125 Moisture Analyzer High-temperature absolute humidity sensor for industrial process control, using a patented solid-state humidity measurement process that provides accurate moisture readings without chemicals, compressed air, wet bulb techniques, optics, or mirrors. Measures absolute humidity at temperatures up to 1200°F / 650°C and is used in stacks, ducts, flues, ovens, furnaces, calciners, kilns, dryers, and fuel cells across power generation, paper production, and general industrial applications.
• MAC155 Moisture Analyzer Premium high-temperature humidity measurement instrument with built-in calibration system for continuous stack monitoring and U.S. EPA CFR Part 60/75 compliance. Provides daily 2-point in-situ calibration and system checks using internally generated reference gas from a tank that supplies one year of daily checks, and measures humidity in exhaust gases up to 1200°F (650°C), with optional extension to 2400°F (1300°C) via special mounting hardware.
• MAC116 Steam Analyzer Steam analyzer specifically designed for continuous conveyor ovens cooking meat and poultry. Controls steam flow into cooking atmospheres to maintain optimal moisture levels for maximum product yield and minimum cooking time. Features a NEMA 4X/IP66 waterproof stainless steel enclosure and a built-in purge system suitable for CIP operations in food processing plants.
• Steam Flow Meter Mechanical steam flow meter operating on critical flow principles using a proprietary venturi flow nozzle, providing true mass flow measurement independent of changing line pressure. Built with 300 series stainless steel construction and a mechanical display for steam-to-atmosphere and open tank applications such as end-of-run steam usage.
• Steam Flow Rate Transmitter Electronic steam flow measurement and control device providing analog output signals (4-20mA, 0-20mA, 0-5VDC) suitable for driving remote digital indicators, chart recorders, or closing the loop to a process controller. Provides true mass flow measurement independent of varying line pressures, with available sizes from 250 lb/hr to 5,000 lb/hr.

Quantifiable outcome

• Paper mill savings of $133,700 annually by controlling exhaust dew point temperature, based on 500,000 kg/day production and 350 operating days per year
