MC142 -
Powertek LLC
Multifunction calibrator MC142 is a precision voltage, current and power calibration source serving as a measurement standard in calibration laboratories and production lines; where verification of electrical measurement equipment & sensors is required. It can be used for calibration and adjustment of meters measuring voltage, current, power, resistance, capacitance and frequency. Internal harmonic and non-harmonic signals make it possible to test electrical performance of meters using signals with various crest factors. Frequency modes enable selection of frequency, amplitude and duty cycle of the output signal. These are suitable for basic calibration of digital and analog oscilloscopes along with transient recorders. The calibrator is equipped to measure temperature with TC and RTD temperature sensors. Its built-in multimeter can be used independently or simultaneously with the calibrator output. Testing of transducers of various types, regulators and sensors can be performed, without the necessity to use any other measuring instrument.

THW-L2 -
Thermtest Instruments
Designed with speed and operational simplicity in mind, the Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896-19. In less than 2 seconds, a single measurement of small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. Using a non-stationary measurement approach, the THW-L2 uses rapid test times to limit convective effects for samples with a wide range of viscosities. The THW sensor consists of a 60 mm heating wire that is fully inserted into an isothermal sample. A constant current source (q) is used to heat the sensor wire and the temperature rise is recorded by monitoring the change in electrical resistance of the wire. The slope (m) is determined from the plot of temperature rise vs. logarithm of time and is used in the calculation of thermal conductivity (λ). Liquid samples of high thermal conductivity will have a lower slope, while liquid samples with low thermal conductivity will have a higher slope.

IBEKO Power AB
Contact resistance measurement is one of the most important and common tests during switchgear manufacturing, commissioning and maintenance stages. Besides switchgear testing, the RMO digital micro-ohmmeters are designed for simple, safe and efficient testing of:disconnecting switches,high-current bus bar joints,cable splices,welding joints,and different high-current links in factory and high-induction field environments.All DV Power RMO micro-ohmmeters use Kelvin’s 4-point measurement principle which is the most convenient for very small resistance measurements. The measurements are accurate and in accordance with international standards for AC high-voltage circuit breakers testing (IEEE C37.09 and IEC 62271-100).Starting from 2003, DV Power has been a trend-setter on the market when our first 500 A micro-ohmmeter weighing only 8 kg (RMO500A / CPM500) was released.Currently, DV Power products portfolio includes 16 models, divided into 3 series:13 portable models: RMO-A (6) and RMO-G (7) series.6 handheld models: RMO-H (6) seriesThe instruments generate a user-selectable and ripple-free test current up to 800 A in an automatically regulated test ramp. Test current ramping significantly decreases the influence of the magnetic transients to measurement.

RMO-E Series -
IBEKO Power AB
The RMO-E instruments are designed and ideal for testing protective bonding (grounding) of equipment following the standard IEC 61010-1. Also, they can measure the resistance of high, middle and low voltage circuit breakers, high-current bus bar joints, cable splices, and welding joints. The instruments accurately measure not only in factory environments but also in high-induction fields and substations.Both models generate a true DC ripple-free (less than 1 %) current with automatically regulated test ramps. During a test, the protective bonding testers automatically generate increasing current before measuring and decreasing current after the measurement. Consequently, this significantly decreases magnetic transients and ensures great accuracy.These instruments can store up to 500 measurements in the internal memory and have a built-in thermal printer available as an option.DV Win software communicates with the RMO-E earth resistance meter via USB or RS232 interface. It allows a user to run the test remotely from PC, as well as to download test results, analyze and generate fully configurable test reports.The RMO-E series contains two models, RMO60E and RMO100E. The main difference between these two models is in the maximal test current:60 A DC for RMO60E100 A DC for RMO100E
