Differential Voltage Probes
DP150/DP200pro
-
The DP differential isolation probes are an important accessory for any laboratory involved in power electronics and high voltage systems. These probes allow isolated and floating measurements with any oscilloscope or data recorder, whilst the oscilloscope can remain grounded. Using a DP150 or DP200pro probe, differential and floating measurements can be made on a variety of ac power systems like 230V/110V ac input power supplies, chopped and switching power supplies, thyristor controllers, variable speed motor drives (PWM signals), motor inrush current and measurement across current shunts. The isolated input is made via two 4mm/banana safety sockets. The BNC output allows easy connection to an oscilloscope. The DP probes can be powered from a 9V battery or external power supply.

Battery Voltage Recorder
BVR Series
-
Battery voltage recorders from BVR series are designed to serve as a support tool for cell voltage measurement during battery capacity testing.During capacity testing, cell voltage, temperature, inter-cell connection voltage, and specific gravity should be measured in order to determine failling cells in the string that should be replaced.Furthermore, IEEE standards for stationary batteries applications stipulate periodical measurement of overall string voltage, as well as cell voltage and temperature.The BVR Series is the perfect tool for that purpose. All measurements are automatically saved in device’s internal memory. Additionally, DV-B Win software helps the user to download all measured results. Furthermore, the user can create test reports and export them to various formats.BVR series includes two models: BVR11 and BVR22. These are rechargeable handheld devices intended for performing monthly battery inspections and support tools during capacity testing. The list of the applications of these instruments includes:Efficient supplement to BLU series of battery load units during battery discharge testingMonthly inspections of large battery banksAmbient temperature measurementCurrent measurement using current clampsUSB and Bluetooth communication with PCSimultaneous string voltage and current measurement to analyze a discharge test processThe BVR22 model provides Bluetooth communication with an external density meter, for transferring electrolyte specific gravity and temperature readings.
