FPA 4100™ UV Digital Photometers
Description
Overview
The FPA 4100™ UV Digital Photometer family enables measurement of the concentration of a wide variety of analytes in both liquid and gas streams. The photonics module can accommodate either UV or visible light sources and features a temperature-controlled photodiode block for maximum signal stability, with the light source and detectors coupled to a measurement cell via fiber optic cables.
Backed by manufacturer datasheet documentation, Seven Star LLC proudly offers the FPA 4100™ to chemical processing plants, refineries, and water treatment facilities across the Sultanate of Oman, Muscat, and the wider GCC. Delivering the utmost in ease-of-operation, precise measurements, and consistent, field-proven performance and value, the FPA 4100™ gives process engineers a versatile photometric measurement platform for both gas and liquid analytical applications, and reduces the number of dedicated single-parameter analyzers a facility must stock, install, and maintain across its process footprint.
Measurement Principle
The FPA 4100™ achieves ±2% of full scale accuracy, repeatability, and linearity, with 1% sensitivity and a response time of 30 seconds (T-90), fast enough to catch transient excursions that a slower-responding wet-chemistry analyzer would miss entirely. Zero drift is compensated through daily auto-zero, keeping the instrument stable over extended unattended operation periods without requiring reagents or compressed gases for continuous measurement.
Because the light source and detector electronics are isolated from the process and coupled via fiber optic cables to the measurement cell, the FPA 4100™ achieves optimum safety and stability even when analyzing corrosive or hazardous process streams. Multi-stream analysis capability allows a single unit to monitor several process points, reducing the total instrumentation footprint compared with dedicated single-stream photometers, and simplifying operator training since a single interface and calibration routine covers every monitored stream.
Engineering Design of the FPA 4100™
The FPA 4100™ controller includes an intuitive user interface with an intrinsically safe, removable keypad, LCD screen, 10 LED indicator lights, and data-logging capability. Auto-calibration using external standards, auto-zero compensation, and digital optimization of detector gains simplify ongoing operation and maintenance, while rugged construction supports continuous industrial deployment.
Measuring 610mm H x 400mm W x 25mm D and weighing 30 kg, the FPA 4100™ operates on either 10-36VDC or 90-240VAC power at 30 watts, with a sample flow of 0.5-1 L/min. The FPA 4100™ series enables remote operation and diagnostics via Ethernet connection, and communicates via Modbus RS232, RS485, and optional TCP/IP protocols for integration with plant control systems.
Key Features
The FPA 4100™ combines flexible photometric measurement with rugged, field-proven construction. Core capabilities include:
- UV or visible light source options with temperature-controlled photodiode block for signal stability.
- Multi-stream analysis capability with no reagents or compressed gases required.
- Auto-calibration using external standards and auto-zero compensation.
- Fiber-optic coupled measurement cell isolating detector electronics from the process.
- Intrinsically safe, removable keypad with LCD screen and 10 LED indicator lights.
- Remote operation and diagnostics via Ethernet connection.
- Modbus RS232, RS485, and optional TCP/IP communication.
- CSA Class 1 Division 2, Groups BCD certification, with field certifications available upon request.
Industrial Applications
The FPA 4100™ is well suited to chemical processing, refining, and water treatment applications across Oman requiring precise photometric analyte concentration measurement in gas or liquid streams. Its reagent-free, multi-stream design makes it a cost-effective solution for facilities monitoring multiple process points without the ongoing consumable costs of wet chemistry-based analyzers.
Working closely with plant engineers in the region, Seven Star LLC supports chemical processing plants, refineries, and water treatment operators throughout the Sohar and Salalah economic zones and the broader GCC region with the FPA 4100™’s versatile photometric analysis capability.

Why Choose Seven Star LLC for Photometric Analyzer Sourcing
Specifying a UV/visible photometer correctly depends on matching the photodiode and light-source configuration to the exact analyte, wavelength range, and sample matrix in question – a mismatch at order time is expensive to correct after commissioning. Seven Star LLC’s engineers review the target stream (gas or liquid, expected interferents, hazardous-area classification) with the customer before the FPA 4100™ is ordered, confirming the CSA Class 1 Division 2 rating and fiber-optic isolation suit the installation’s actual area classification rather than assuming a default configuration will fit. We also plan spare photodiode blocks and fiber-optic cable assemblies alongside the initial order, since analyzer downtime on a continuous monitoring loop is rarely acceptable, and we coordinate freight and customs clearance into Muscat, Sohar, and Salalah so replacement components reach site quickly rather than sitting in transit during a process upset.

Ordering Galvanic analyzers and parts: what we need
For a new Galvanic H2S analyzer or chromatograph, send the stream composition, the component and range to be measured, sample pressure and temperature, the number of streams, area classification, power supply and the outputs required. For consumables and spares such as sensing tape, lamps, columns or pump parts, send the analyzer model and serial number and the part number from the manual. Manuals differ by generation, so a nameplate photo helps us check the item against the manufacturer's documentation.
