Reflectometer

Diagnose faults with TDR-420 The TDR-420 reflectometer is a handy digital Time Domain Reflectometer (TDR) designed to characterize and locate faults in power and telecommunications cables. The Sonel TDR-420 reflectometer allows to measure the length of the cable and to determine the distance to the damage or impedance change in the range from 4 to 6000 m in cables with metal conductors. The shortest measuring range of 7 meters and the dead zone of 0.6 m allows user to locate a damage in a very short distance from the connection point of the device. Product features fault location in power and telecommunication cables two independent cursors to indicate two fault locations and the distance between them fault location in coaxial cables fault location in infrastructure cables detection of breaks, short-circuits, damage caused by moisture and other changes in cable impedance graphic presentation of cable faults with an indication of the distance to the fault on the display Application TDR-420 time-domain reflectometer is designed to detect where faults in metal wires are. This product is designed for: electrical wholesalers and cable dealers, electrical installation companies, maintenance personnel at manufacturing plants, building personnel. This device meets the expectations of all those who have to accurately locate a fault and wire end in either power or telecommunications cables. Device capabilities SONEL reflectometer is distinguished for their long operating range of up to 6,000 m, very low margin of error in measurement (in the order of 1%) and the ability to adjust both the velocity of propagation and the impedance of the cable which is under investigation. By using two cursors there should be no problem with determining both the distance to two faults and the distance between them. Easy readout The TDR-420 reflectometer is equipped with a readable colour display that, due to its 320 x 240 pixel resolution, allows the fault location to be indicated even more accurately. Integrated Help In the TDR-420 device a handy help function has been added to facilitate the interpretation of the result obtained during measurement. Thanks to this function, a user can quickly determine the type of anomaly that is present in the cable segment which is being examined, by comparing the displayed reflectogram with typical fault shapes. Durable and practical casing In response to the customers needs the new TDR-420 model has been designed to operate in difficult environmental conditions. A unique casing with the IP67 ingress protection rating ensures that the device is both waterproof and dustproof. An additional advantage is the elastomer coating of the casing that prevents the device from slipping out of the hands and provides protection if it should be accidently dropped.

Sign reflective measuring instrument is a new type of portable trafic safety detection equipent, which is used to measure the reflective optical characteristics of various reflective safety sign and can be used for on site detection of trafic reflective products and vehicle safety reflective products,

Simple operation 'Auto selection' of gain and pulse width Ultra fast pulse for near end fault identification Trace 'Hold' feature IP54 rating offers real life working Designed for use on all metallic cable pairs The TDR500/3 is a handheld single channel time domain reflectometer (TDR) for locating faults on metallic cables. It is compact, can be used on all metallic cable pairs, and has a minimum resolution of 0.1 m and a 5 km maximum range, depending on velocity factor selected and cable type. The TDR500/3 is easy to use and has four output impedances available (25, 50, 75, and 100 ) and a velocity factor between 0.2 and 0.99 will meet any cable test requirements. It also has a trace hold feature and a velocity factor between 0.2 and 0.99, so you can meet any cable test requirements. The TDR500/3 has a simple selection option which, together with a four-way control switch, offers your intuitive operation. The 'Auto selection' option ensures that the most effective parameters are selected depending on the range required, aiding rapid diagnosis of the TDR trace. A clear operator-controlled cursor allows instant measurement of the distance to the fault and a trace 'Hold' feature also allows you to hold a trace on the screen, something not seen on most other handheld TDRs. Extra high resolution together with a white-light backlight and grey scale tones make the graphical display vibrant, helping you to identify key events on the trace.

LTL3000 is part of a new generation of DELTA retroreflectometerinstruments for measuring retroreflection of road markings. Theinstrument is based on the latest technological developmentsand with modern design and materials. LTL3000 is, like all otherDELTA instruments, very easy to calibrate and operate, we like tosay very user-friendly . And the instrument is of course robustand long lasting like our earlier generations of road markingretroreflectometers and on top of this small in size (420 x 300 x 150mm / 16.5 x 11.8 x 5.9 inch) and light in weight (4.7 kg / 10.4 lbs.).LTL3000 is primarily intended for users who need an instrument forless demanding measurement programs, who want an instrumentwhich is easy to transport and who do not need many features tosupport the measurements

The Road Stud Reflectometer is a specialized testing device used to measure the retroreflective efficiency and visibility of road studs or pavement markers under vehicle headlight conditions. It evaluates the amount of light reflected back from the road stud toward the driver, helping determine its nighttime visibility and safety performance. The instrument is widely used in highway engineering, road safety inspections, and maintenance projects to assess the condition and effectiveness of reflective road studs, ensuring compliance with traffic safety standards and improving driver guidance during low-light or adverse weather conditions.

Measurement of wafer reflectivity after texturing.Ensures uniform texture quality to achieve requiredlight‑absorption characteristics.

Refractometers measure the degree to which the light changes direction, called the angle of refraction.

The OTDR set up trains the user on OTDR operation, at fraction of a commercial OTDR cost. The user configures the OTDR and works with several fibre events provided. The manual explains the concepts, the functionality of different blocks, different experiments and the commercial applications. Modular fibre events with connector and adaptor at various distances are part of the lab to work with experimental OTDR. Other events can be added on request to capture the fibre bending effect, splice loss etc.
