Product Overview
Ircon is a Fluke Process Instruments legacy product-line brand — every current Ircon product is now the Endurance series sold under FPI branding. This reference maps the discontinued Ircon installed base (Modline 3/4/5/6/7, Mirage, Infrarail, Javelin, SR Series, UltiMax Plus, Series 1100, ScanIR II, and the older Maxline / Modline Plus generation) to the current successor series, and existing installations are still supported in the field. The mapping is governed by one rule above all: the measurement principle is preserved. An Ircon 2-color (ratio) instrument — the Modline 5R, the fiber Modline 6R, and the Mirage OR — always migrates to a ratio successor (Endurance E1R/E2R, or fiber EF1R/EF2R), never to a single-color sensor; a single-color Ircon sensor follows a single-color path (Thermalert 4.0 or Endurance 1M/2M/3M). Match by the old nameplate or part number and the process data, and the right replacement — with the adapters to reuse existing mounting and optics — follows.
Key Features & Benefits
- Every Ircon line has a defined successor — the Modline, Mirage, Infrarail, SR, Javelin, and ScanIR families all map to a current FPI series, so a failed or aging Ircon sensor is a planned replacement, not a dead end. The install base is not stranded.
- Ratio stays ratio — by rule, not by guess — an Ircon two-color instrument (Modline 5R, 6R fiber, Mirage OR) is matched to an Endurance ratio successor that measures at two wavelengths the same way, so it keeps reading through dust, steam, and an underfilled spot. The reason the legacy ratio sensor was chosen is the reason the successor is a ratio sensor.
- Reuse the mounting and optics where possible — an Endurance head can drop into an existing Ircon install on the original flange, water jacket, and (for fiber) optical-head hardware — the adapter kits that make that work are listed in the specifications. The replacement reuses the hole, the cooling, and often the fiber.
- One reference, sourced against the original price book — the mapping reconciles the 2011 Ircon price list against the current FPI part-number guide, so a model that looks orphaned is placed against a real, orderable successor. Bring the nameplate; we place it.
Specifications
- Status
- Discontinued. The Ircon Modline (3/4/5/6 and the later Modline 7), Maxline, Mirage, Infrarail, Javelin, SR Series, UltiMax Plus, Series 1100, and ScanIR II lines are no longer manufactured. Installed units are still supported in the field and have defined migration paths to the current Fluke Process Instruments series.
- Current successor families
- Endurance integrated (E1R/E2R 2-color ratio · E1M/E2M/E3M single-color) and Endurance Fiber Optic (EF1R/EF2R ratio · EF1M/EF2M single-color) for the Modline / Mirage / SR install base; Thermalert 4.0 for the compact single-color sensors (Modline 4, Javelin); ScanIR 3 / MP150 for the ScanIR II line scanner; the GP Monitor for the TempView indicator.
- Measurement principle
- Preserved on every path. A migration matches the legacy spectral response (wavelength), temperature range, and optics — and, above all, the measurement principle: a 1-color (brightness) Ircon sensor maps to a 1-color successor; a 2-color (ratio) Ircon sensor maps to a 2-color successor.
- How a successor is matched
- Matched from the legacy nameplate and/or full model number (which encodes the spectral response, temperature range, and optical resolution) plus the current process data. The old Ircon part number is the most reliable starting point.
- 2-color (ratio) preservation
- Ircon’s ratio instruments — Modline 5R, Modline 6R (fiber), and the Mirage OR (standard and fiber) — migrate only to a ratio successor: Endurance E1R/E2R (integrated) or EF1R/EF2R (fiber-optic). A ratio instrument is never routed to a single-color successor.
- Legacy support scope
- Prater Technical Partners recommends the correct successor and the adapters that let it reuse existing mounting, cooling, and (for fiber) optical-head hardware where possible — FPI publishes Modline-footprint mounting flanges and M5/WJ-5 adapter kits for exactly this. Factory calibration and repair of legacy units routes through the Fluke service center.
- Software & configuration
- Legacy ModView / Spotmaster / ZoneMaster configuration gives way to the current Endurance and Thermalert 4.0 software; ScanIR II Spotmaster / Float-Glass Profiler installs migrate to ScanView Pro (ScanIR 3) or DataTemp DP / MP-SYS (MP150).
- Spares, cable & calibration
- Sensing heads, indicator/processor boards, lenses, cables, sight tubes, water jackets, and air-purge accessories for legacy Ircon units were catalogued in the 2011 price list and some remain available as spares; NIST/DAkkS-traceable calibration is offered on the current successor at order time.

Common Applications
- Cement & lime — rotary-kiln burning-zone and shell scanning where Modline ratio sensors and ScanIR II scanners are still in service
- Primary & secondary metals — reheat furnaces, induction and forging lines running legacy Modline and Mirage brightness / ratio sensors
- Glass — float and container lines on legacy 5 µm Modline / Mirage and ScanIR II glass profilers
- Heat-treat, sintering, and high-temperature furnaces with fiber-optic Modline 6 / SR heads in the hot zone
- Maintenance-driven replacement — one failed Ircon sensor at a time, matched to a current Endurance or Thermalert 4.0 successor that drops into the existing mount
This is a migration reference, not a product line. If your Ircon model is not in the table, or the table says “contact for application match,” send the nameplate / part number and the process data and we will identify the correct successor — preserving the measurement principle — rather than guess at a part number. For the Raytek installed base (Marathon, MR, XR, ThermoView), see the Raytek legacy migration reference.
Design & Selection Considerations
- Read the spectral response off the old model number first — an Ircon part number encodes the wavelength (e.g. Modline 3 200 Series = 0.7–1 µm, 340 Series = 3.43 µm, 700 Series = 5 µm). The successor has to match the same band — a glass (5 µm) sensor cannot be replaced with an 8–14 µm one. Wavelength is the first thing to carry across, not the last.
- Confirm 1-color vs 2-color before anything else — the “R” in Modline 5R / 6R and the “OR” in Mirage are the ratio tell; if the nameplate shows ratio, the only correct successors are Endurance E1R/E2R or EF1R/EF2R. Mixing principles silently changes how the sensor behaves through obscuration. This is the one decision the migration rule will not let you get wrong.
- Decide whether the fiber head moves with the sensor — fiber Ircon units (Modline 6, Mirage fiber, SR fiber) put the optical head in the hot zone and the electronics out of it — the Endurance Fiber line is the like-for-like path, and the existing roof-mount or sight-tube hardware often carries over. A fiber install almost always wants a fiber successor.
- A two-color portable has no like-for-like handheld today — the UltiMax Plus UX70P offered a 2-color portable mode; the current Raynger 3i Plus is single-color. If the ratio mode was the reason the UX70P was bought, the honest answer is a fixed Endurance ratio point at that location, not a handheld — so tell us how it was actually used. We will not pretend a single-color handheld is a ratio replacement.
- Plan the scanner migration as a system, not a sensor swap — a ScanIR II replacement (ScanIR 3 or MP150) brings new software (ScanView Pro / DataTemp DP) and new I/O; FPI offers direct-replacement housings, but the data link and outputs change. Scope the control-room side along with the scanner.
To match a discontinued Ircon sensor to its successor:
Use the input form to send us the legacy nameplate and, ideally, the full model / part number off the sensor (it encodes spectral response, temperature range, and optics). Add: the target material and its emissivity, the process temperature range, whether the instrument is single-color or 2-color (ratio), the current optics / distance-to-spot and working distance, the output and communications the control system expects, and any mounting, cooling, or fiber-optic hardware already in place that the replacement has to reuse. With that we confirm the correct current successor — preserving the measurement principle — and the adapters, cables, or mounting kits that let it drop into the existing installation.
