Products and services

• METIS M311 2-Color Pyrometer Short-wave 2-color (quotient) pyrometer for non-contact temperature measurement on metals, ceramics, graphite, and other materials. Features measurement value acquisition under 0.5ms, response time under 1ms, and temperature ranges from 600°C to 3300°C depending on model variant. Designed for industrial customers requiring precise high-speed measurement in metal processing and similar applications.
• METIS M3F1 Flame Pyrometer Specialized 2-color pyrometer using a special algorithm to detect flame properties such as optical layer thickness (soot concentration) and penetration depth from single-color and quotient measurement values to determine flame temperature. Used for non-contact temperature measurement of sooty flames in coal-fired power plants, waste incineration plants, and other incinerators to optimize combustion, reduce emissions, and avoid slagging of combustion chamber walls.
• GALAXY Line Scanners (SC7/SC8) Line scanners that move the spot size of a pyrometer continuously over objects and record temperatures at even angular intervals. With adjustable measuring angle between 0.56° and 90°, they record 10 to 1600 measured values and feature 16 separately evaluable measurement regions. Used for temperature profile capture and 2D thermography in quotient mode.
• REGULUS PID Program Controllers (RD/RF) Pyrometer-optimized PID program controllers with programmable control steps, direct output of manipulated variable, extremely fast sampling time (up to 100 µs), and automatic P-I parameter determination. Available in desktop housing or panel mounting versions. Designed for closed-loop temperature control in laser and other dynamic thermal processes.
• CS1500N Calibration Source Calibration source for verifying and readjusting infrared measuring devices according to the International Temperature Scale of 1990 (ITS-90). Features temperature range between 50 and 1500°C, 40mm aperture, and emissivity of cavity above 0.99. Forms a complete calibration system when combined with PC and pyrometer connections, with fast heating times and long-term stability.

• SensorTools PC Software Comprehensive adjustment, communication and analysis software included with all Sensortherm pyrometers, scanners, controllers, displays, and calibration sources. Enables device settings, temperature display, recording of measurement curves, single-point pyrometer adjustment, and automatic PI control parameter determination. Supports recording intervals from 50 µs for high-speed pyrometers.
• SensorCal3 Calibration Software Software for accuracy checking and readjustment of calibration sources, with automatic pyrometric readjustment using the DIADEM Transfer Standard Pyrometer. Included with Sensortherm calibration sources for creating pyrometer calibration certificates and performing single-point adjustment.

Used in hot strip rolling mills, continuous casting plants, and casting machines.
• Calibration and Testing Services Calibration certificates according to IEC 17025, factory certificates, device readjustment, and verification services for Sensortherm pyrometers. Includes support at commissioning and is recommended at least every 2 years for infrared measuring devices.
• Repair and Maintenance Services Repair service for defective Sensortherm devices, maintenance, and calibration services. Operates through an RMA process for sending devices in for service, with 2-year warranty coverage.
• Training and Seminar Services Seminars and training courses on infrared measurement technology, pyrometer techniques, calibration, and application-specific optimization. Conducted in Steinbach, on-site at customer locations, or via video conference for industrial customers using Sensortherm products.

Broad incumbents

• AMETEK Land: AMETEK division supplying infrared pyrometers, line scanners, and combustion monitoring for steel, glass, power, and incineration — overlapping directly with Sensortherm's verticals. Operates at significantly larger scale with global sales and service infrastructure.
• Advanced Energy (Impac / LumaSense): Acquired Impac and LumaSense, both long-standing pyrometer specialists. Directly competes with Sensortherm in industrial and R&D temperature measurement, particularly 2-color pyrometers, with the resources of a multi-billion-dollar public parent.
• Fluke Process Instruments (formerly Raytek / Ircon): Global brand within Fortive offering fixed-mount infrared pyrometers, line scanners, and thermal imagers for industrial process control. Competes head-to-head with Sensortherm's METIS and GALAXY lines, but with much broader portfolio, global service network, and corporate backing.
• Endress+Hauser: Global leader in industrial process instrumentation including temperature measurement. Sensortherm competes indirectly where Endress+Hauser's broader portfolio addresses similar industrial measurement applications, though Endress+Hauser does not specialize in high-speed 2-color pyrometry.
• Omega Engineering: Broad industrial sensor and instrumentation supplier offering infrared pyrometers and temperature measurement products. Overlaps with Sensortherm at the entry-level and mid-range of the pyrometer market, with vastly larger catalog and distribution reach.
