Product Description

To gain the trust and confidence of a vast clientele, we are engaged in manufacturing and supplying Portable Multifunction Calibrator. In laboratories these are used as electric quantity meter testing equipments. These equipments are manufactured under the firm inspection of the expert supervisors making use of superior grade materials and components. The clients can avail our Portable Multifunction Calibrator at the cost effective prices. We always deliver our range of electronic products to the clients within the stipulated time frame.

Our portable Multifunction calibrator of version M143 is cost sparing solution for adjustment of meters of electric amounts of around 1000 V and 20 A. This provides essential precision 0.01% in DC current demanded for alignment of 3½ as well as 4½ digit multimeter. Resilience capacity is secured by eight settle resistors in array varying in between 10 to 100 M. The adjuster provides TC temperature detector simulation. Our portable multifunction calibrator can be supplied alternatively also with RTD temperature detector test system. Because of its compact measurements and in addition, its low weight the adjuster can be used effectively for field alignments.

The calibrator primary utilization area are manufacturing units of multimeter., measuring amplifiers, calibration labs, panel meters, transducers and thermometers, where the adjuster can be used as root of normal value for verifications, adjustments and calibrations of lines under inspection.

Interface RS-232 as well as alternatively GPIB interface bus help computerized working in remote state providing efficient programmed adjustments. Version M143 is completely perfect with Meatest alignment SW pack WinQbase and CALIBER.
