Transformer Ratio Meters
Handheld Turns Ratio & Winding Resistance Tester TWR-H
TWR-H is a handheld, battery operated, fully automatic test set specially designed for turns ratio, phase shift, excitation current and winding resistance measurements of transformers. It can also perform demagnetization of these transformers. Transformer turns ratio is determined by applying AC voltage across high voltage winding, accurately measuring AC voltage across the corresponding unloaded transformer winding, and then displaying the ratio of these voltages. User can enter a transformer’s nameplate voltages, so that turns ratio deviation can be calculated. This feature eliminates any error otherwise caused by an operator’s manual calculation. TWR-H compares measured turns ratio with the nameplate ratio and prints out the % of error for each test. Transformer winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current. The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from transformer magnetic circuit are automatically regulated.

Gas Filter Correlation Carbon Monoxide Analyzer
Model T300
The Model T300 measures low ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 14 meters. The energy loss through the sample cell is compared with the span reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing extreme sensitivity. 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, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T300 comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

SNR Noise Generator
CNG-EbNo
The CNG-EbNo is a fully automated precision signal to noise (AWGN) generator that sets, and maintains a highly accurate ratio between a user supplied carrier and internally generated noise, over a wide range of signal power levels and frequencies. The internal AWGN meter provides repeatable SNR waveforms for accurate signal generation. The instrument gives system, design, and test engineers in the telecommunications industry a single tool to generate precision signal to noise ratios. These signals are used to compare theoretical BER to SNR ratios, found in "waterfall" type graphs, with measured values from the DUT to evaluate different modulation schemes. Users can obtain higher yield through automated testing, plus increased confidence from repeatable, accurate test results. Standard units can be modified for specific customer requirements. Please consult the factory for pricing and availability of these requests.
