Anritsu FL Series Fiber Optic Thermometers – FL-2000 & FL-2400
The Anritsu FL Series uses fiber optic probes to measure temperature in microwave, high-voltage and strong electromagnetic environments where conventional electrical probes may be unsuitable.
FL-2000: one measurement channel.
FL-2400: four measurement channels.
0.1°C resolution.
Probe options for chemicals, intense light, high temperatures and semisolid samples.
Analog output and RS-232C communication.
Probes are ordered separately. The usable temperature range depends on the selected probe.
The Anritsu FL Series measures temperature using dedicated fiber optic probes in applications exposed to microwaves, strong electromagnetic fields or high voltages. Choose the FL-2000 for one measurement channel or the FL-2400 for four channels.
The optical sensing method provides an alternative where electrical interference makes conventional temperature probes difficult to use. Select the probe for the actual temperature, material and installation conditions.

Extension Cables and Installation Accessories
Check the complete optical connection arrangement, routing and mechanical support before selecting extensions or fittings.
FK1-*M General-Purpose Extension Cable
Extension cable for standard installations.
FK2-*M Heavy-Duty Extension Cable
Extension cable for more demanding installation environments.
FA1 Connection Adapter
Connects a probe to an extension cable.
FN1-T Compression Fitting

FN1-V Compression Fitting
NPT 1/8 fitting with Viton sealant material.
For a vacuum or pressure-vessel installation, confirm the rating of the complete probe-and-fitting assembly at the operating temperature. The published FN1 test uses a stainless steel rod and must not be treated as an unconditional pressure rating for every fiber probe installation.
PC Connection and Data Collection
The existing product documentation specifies AMS-850 software and RS-232C communication. The FL-2000 provides internal memory, whereas the FL-2400 requires an external data-collection arrangement when records are needed.
Confirm software, operating-system and connection compatibility before ordering. The existing page lists older Windows versions; it does not establish Windows 11 support.

Choosing an FL Measurement System
Measurement points: decide whether one or four channels are required.
Environment: describe the microwave, electrical, magnetic or light exposure.
Probe contact: specify the surface, liquid or sample, including chemical composition where relevant.
Installation: provide cable length, routing, mounting and any vessel-entry requirements.
Records and outputs: identify whether you need PC data collection or an analog signal.
