The Yokogawa AQ6370 is a flagship series of bench-top Optical Spectrum Analyzers (OSAs) designed for high-precision analysis of light signals in telecommunications, photonics research, and manufacturing. This series is renowned for its superior performance, including high resolution, wide dynamic range, and excellent wavelength accuracy.

The Yokogawa AQ6373 is a bench-top Optical Spectrum Analyzer (OSA) designed for high-precision analysis of light signals in the O-Band. It is a specialized instrument, optimized for the wavelength range used in Single-Mode Fiber (SMF) transmission around the 1310 nm window.

The Yokogawa PW48210 is a DC Power Supply Module designed for installation in Yokogawa's proprietary PLC (Programmable Logic Controller) or DCS (Distributed Control System) racks, such as those from the FA-M3 or other Yokogawa control families.

The Yokogawa SB401-10 is a Signal Conditioner or Signal Converter. It is a modular, single-channel unit designed to be mounted on a DIN rail inside a control panel or system cabinet.
Its primary function is to electrically isolate and convert a standard analog signal. It accepts a 4 to 20 mA DC input signal from a field device (e.g., a pressure or temperature transmitter), processes it, and produces a corresponding 1 to 5 V DC output signal for receiving devices like PLCs, DCSs, or recorders

The Yokogawa ANB10D-420 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Dual Isolator and Converter.

Its primary function is to accept two independent 4 to 20 mA DC analog input signals from field transmitters (e.g., pressure, temperature, flow), provide electrical isolation between the input, output, and power supply circuits, and convert each input into a corresponding 4 to 20 mA DC output signal.

The Yokogawa AQ6317B is a bench-top Optical Spectrum Analyzer (OSA) and a classic workhorse in the field of optical fiber communications. It is designed for the precision measurement and analysis of light signals across a very wide wavelength range, making it exceptionally versatile for both telecommunications and general photonics research and development.

The Yokogawa AQ6370C is a bench-top Optical Spectrum Analyzer (OSA) designed for high-precision analysis of light signals in the telecommunications C-Band and L-Band, as well as for general photonics research and development. It is a member of Yokogawa's renowned AQ6370 series.

The Yokogawa DM1015B00 is a Compact Digital Indicator or Digital Panel Meter. It is designed for local display of a process variable on a control panel, machine, or small enclosure. This model is a more compact and potentially cost-optimized version compared to the larger DM1060 series.

The Yokogawa UD1AG3 is not a field instrument like a pressure transmitter or flow meter, but rather a Signal Conditioner. It is a key component of Yokogawa's UTAdvanced series of signal converters, designed to be mounted on a DIN rail inside a control panel or system cabinet.

The Yokogawa DM1060B00 is not a field instrument like a pressure transmitter, but rather a Digital Indicator or Digital Display Unit. It is designed to be mounted on a control panel or console to provide a clear, digital readout of a process variable, such as temperature, pressure, flow, or level.
