Pole-zero analyzer

A pole-zero analyzer includes an autocorrelation impulse response calculator, first and second buffers, a pole parameter value table, a first coefficient calculator, a first inverse filter, a second coefficient calculator, a second inverse filter, a pole-zero calculator for calculating a pole parameter and a zero parameter in response to outputs from the first and second inverse filters and calculating an error value for determining the pole parameter, a buffer memory for generating an output from the pole parameter value table obtained when the error value satisfies predetermined conditions and predetermined portions of the zero parameter and the pole parameter calculated by the pole-zero calculator as outputs of the pole-zero analyzer, and a control circuit for controlling operation timings of the respective parts.

RAH-210 Residual Chlorine Monitor & Analyzer

Our line of chlorine residual monitors includes Hydro Instruments' ampermetric analyzer. The Series RAH-210 Analyzer determines residual chemical levels in the sample water. The measurement cell consists of large Copper and Gold electrodes in direct contact with the sample water. This reagent-free analyzer is continuous and does not rely on older "sample and hold" methods thus it provides a much improved process control.


Note: Food-grade vinegar can be used as the pH buffer reagent if the water pH varies. If pH is relatively constant and you are measuring free chlorine, no buffer solution is required.

Main Features:
• Measures free, or total chlorine
• Detects Chlorine Dioxide levels
• Monitors Bromine and Iodine
• pH and Temperature Compensation
• Uses food grade vinegar for buffer solution
• Optional PH probe compensation available
• Continuous measurement meter
• Standard PID controller set point residual
• Continuous sensor cleaning mechanism
• Adjustable measurement range
• Alarm contact relay for signal loss
• Two loop powered 4-20 mA inputs and one
4-20 mA output

Maintenance:
A continuously driven cleaning system is employed to prevent a concentration of impurities on the surface of the electrodes which reduces the need for maintenance.

Ultra-Portable, USB-Powered Real-Time Analyzer

Equipped with a 24-bit four-channel USB powered dynamic acquisition module, the SO Analyzer USB4 is the perfect engineering tool for portable noise and vibration applications. It provides highly accurate measurements from audio frequency IEPE (ICP) sensors and all the functionality you need for your daily test job at a surprisingly low price.

Thanks to its self-powered USB 2.0 hi-speed connectivity to a host PC or a laptop, the SO Analyzer is a compact real-time analyzer designed for professional applications in the field and in the laboratory. Measurements have never been so easy: Load the SO software, connect the USB cable between the acquisition module and the host PC/laptop and start your measurement using ICP® sensors powered direct from the USB front-end. With 25 kHz bandwidth, 24-bit resolution and 102 dB dynamic range, the SO Analyzer offers very high precision on four channels and upwards and is perfectly suited for versatile N&V measurements and analyses.

Heat analyzer

A heat analyzer equipped to automatically perform operations necessary for protection of measured data and for restart when a problem occurs or a measurement ends and to quickly turn off all power sources by a command input manually by an operator to a system section after daily use. At least one measurement-section power source 6 which can be turned off by an associated measurement controller 5 and a system-section power source 14 which can be turned off by a system controller 11 are included. When the temperature program of every measurement controller 5 connected to the system controller 11 through data transmission paths 8a to 8c is executed, an external environment sensor 9 detects a problem, or the operator issues a command, the system controller 11 transfers information from volatile memory 10 to a nonvolatile memory 13 before commanding every measurement controller 5 to turn off the measurement-section power source 6 and providing the system-section power source 14 with a control for turning off the system-section power source.

Nitrogen Oxides (NOx) Analyzer

The Model 200AH High Range NO/NO2/NOX Analyzer uses the field-proven chemiluminescent technique for monitoring high levels of oxides of nitrogen. User-selectable ranges of 5 ppm to 5000 ppm make it ideal for a wide variety of applications including CEM, stack testing, and process control. A choice of NO2-to-NO converters handles tough CEM and stack testing applications. Selectable measurement modes (NO only, NOx only, NO/NOx switching), auto ranging and remote range control let you set up the Model 200AH to your exact needs. The modular design offers top-mounted access to all subassemblies and has hinged front and rear panels to simplify module replacement. The modular, sealed ozone generator provides improved voltage coefficient, safety, and reliability. A standard permeation dryer on the ozone generator means there is no desiccant to replace. In addition, the excess ozone is removed by catalytic reaction, eliminating the need for charcoal (expendable) replacement.
