Sulphur Dioxide Test Chambers
The Sulphur Dioxide Test Chambers from Weiber are Corrosion Test Chambers used for testing the corrosion resistance of metallic surfaces and outer protective layer of coatings. They are used to create a highly corrosive environment rich in corrosive gases and natural humid conditions to induce accelerated corrosion in protective coatings of machines and equipments, electrical items, electronic parts and components, mechanical constructions, automobile and aircraft parts and components etc. Since the corrosive action of Sulphur dioxide also depends on specific temperature and humidity conditions and the presence of other contaminants, the Weiber Sulphur Dioxide Test Chambers are designed to create optimal conditions of temperature and humidity and also make provisions for introducing impurities and contaminants. These equipments operate across a wide temperature range, creating variations in the working temperature to mimic a natural weathering environment.

Circuit Breaker Test Equipment
DV Power has released a new generation of circuit breaker test equipment for condition assessment of medium and high voltage circuit breakers.Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages.Applications supported by the DV Power test equipment include measurements of:Contact resistanceDRM (dynamic resistance measurement)Coil resistance and coil current (IEC 62271-100)Mechanism charging time (IEC 62271-100)Minimum trip voltage (IEC 56, ANSI C37.09)Undervoltage release (IEC 60694)The timing of a circuit breaker’s main, auxiliary and pre-insertion contactsSynchronization between the contactsMotion and velocity“First trip” testThe essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.

Handheld Micro-Ohmmeters
RMO-H Series
The RMO-H is battery operated and handheld micro-ohmmeter. It is designed for a variety of applications for contact resistance measurement of non-inductive test objects. Typical applications are accurate testing of:medium and high-voltage circuit breakers,disconnecting switches,high-current bus bar joints,cable splices,and different high-current links.Even more, it accurately measures in high-induction filed environments and substations, as well as in factory testing.RMO-H Series contains six models in total, divided in 2 sub-series depending on the test leads length requirement and the battery type:RMO-H1, RMO-H2 and RMO-H3 models are intended for use with short cables (e.g. 1,3 m / 3 m / 5 m). The 1-cell Li-Po battery with 8200 mAh capacity provides output voltage up to 4,1 V DC.RMO-H21, RMO-H22 and RMO-H23 models are ideal for applications where test leads with lengths > 5 m are required. The high output voltage (up to 8,3 V DC) is provided by 2-cells 4100 mAh Li-Po battery.The test current is regulated and can be selected in a range of 1 A to maximum 300 A, depending on the maximum test current rating:RMO-H1, RMO-H21 models – up to 100 A DCRMO-H2, RMO-H22 models – up to 220 A DCRMO-H3, RMO-H23 models – up to 300 A DC.Unlike many other handheld micro-ohmmeters available on the market, our instruments have regulated and user-selectable test currents. Therefore, RMO-H instruments generate an automatically regulated test ramp with stable and ripple-free current during measurement. These revolutionary characteristics in a handheld micro-ohmmeters technology are possible by using sophisticated Li-Po batteries. Consequently, modern battery technology enables you to do multiple measurements, and a full day of testing without recharging the battery.With all RMO-H models, it is possible to make tests on Both Sides Grounded testing objects, in an increased safety environment. Finally, these features in combination with a user-friendly interface (1-click to measure) significantly speed-up testing procedure and make it safer.These instruments store up to 1000 measurements on the internal micro SD card.Our free DV Win software communicates with the RMO-H micro-ohmmeters via a wireless Bluetooth interface. Furthermore, it allows you to download test results, analysis and generate fully configurable test reports.

Variable Power Supply
VS-10a
The VS-10a power supply is a light weight, portable, non-isolated “variable source” from 0 volts to 150 Vac or 0 volts to 150 Vdc and rated for up to 10 amps, thus the name VS-10a. It is comprised of an illuminated voltmeter that reads to the first significant digit, AC variable system output voltage, DC variable system output voltage, logic output voltage and one sense (continuity) contact monitoring points. Banana jacks for connection of test leads are spaced at intervals that allow the use of dual banana test plugs if desired. The VS-10a is protected by two levels of overcurrent protection; AC input, and ground fault protection by a GFCI. All circuitry is housed inside a custom designed case made from 16 gauge steel. An Internal fan dissipates heat buildup and exhaust through louvered side vents built into the case. The carrying handle is designed with a “spring return to rest” position and is padded for comfort. The case has been sized for optimum portability and is balanced from the handle during transportation. The case has a powder coated finish that is scratch, chemical and weather resistant. Rubber padded feet support the case when in the upright position and a convenience receptacle is located on the side of the case.
