UV Fluorescence Sulfur Dioxide Analyzer
Model T100
The Model T100 uses the proven UV fluorescence principle, coupled with a state of the art user interface to provide easy, accurate, and dependable measurements of low level SO2.Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift and a reference detector to correct for changes in UV lamp intensity. A hydrocarbon ‘kicker’ and advanced optical design combine to prevent inaccuracies due to interferents.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel using NumaView™ Software, or via RS232, Ethernet, or USB com ports, either locally or by remote connection using the included NumaView™ Remote PC Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.The Model T100 comes with NumaView ™ Software.

Dual Channel HV Amplifier with Phase Inverter
A400DI
This unit contains two independent A400 amplifiers that share common ground reference and power supply. Please see A400 page for technical details.It features also a low voltage phase inverter that inverts the signal applied to the input of channel 1. The resulting signal can then be connected to the input of channel 2 by means of a short BNC cable (supplied). As a result the two outputs operate in counter-phase. Connecting a load between the outputs effectively doubles the amplitude range. Please note that the load cannot have any connection to ground.

1.533 Μm Frequency-Locked Laser
Thorlabs' LLD1530 Frequency-Locked Laser is a narrow linewidth, DFB-laser-diode-based, turnkey system with a vacuum emission wavelength of 1532.8323 nm and a high SMSR of at least 35 dB. The laser frequency is actively stabilized to a National Institute of Standards and Technology (NIST)-traceable molecular transition of acetylene and has an absolute accuracy at start-up that is better than ±25 MHz. The emission frequency immediately after start-up is then maintained with a ±25 MHz stability, providing an overall frequency accuracy of ±50 MHz. The LLD1530 is an accurate frequency reference designed to provide low-noise laser emission with excellent frequency stability, accuracy, and precision immediately at start-up. This source is ideal for use in demanding FTIR instrumentation, instrument calibration, gas sensing, and coherent telecommunications applications.

Ultrasonic Sensing
Ultrasonic sensing is the measurement of the time between an ultrasonic signal being sent and received. The interval between these two signals is typically referred to as time-of-flight (ToF) and depends on the distance the ultrasonic wave travels until it is reflected due to an impedance change and the speed of the ultrasonic wave. The basic equation time = distance / speed can be used to measure fluid level, fluid identification/concentration, flow, or proximity.
