732C and 734C DC Voltage Reference Standards
732C and 734C DC Voltage Reference Standards the most accurate and stable 10 V reference in your lab. We offer the lowest price of Fluke calibrator in Bangladesh.
Model: 732C and 734C DC Voltage Reference Standards
The simple way to maintain and disseminate the volt. The Fluke Calibration 732C DC Voltage Reference Standard is a RoHS compliant direct voltage reference used to maintain the volt in primary and secondary standards laboratories.
Individual 732C voltage standards provide 10 V, 1 V, and 0.1 V outputs and may be transported easily to remote locations while the dc reference is maintained in the laboratory.
The Fluke 734C DC Voltage Reference Standard consists of four electrically and mechanically independent 732C DC Reference Standards and a rack-width enclosure. Two model families, Base and Select, differ in that the Select models are two times more stable than the Base models. We Are the Authorize distributor in Bangaladesh and grateful to Tools Bangladesh.
732C and 734C DC Voltage Reference Standards
Key Features:
- The 734C is the only standard of its type offering complete mechanical and electrical independence of each of its four standards.
- Each 732C Standard is designed for portability. Each is small, light, rugged and has long operating battery life.
- The 732C is based on the proven technology of the Fluke Calibration 732A and 732B. The 732A was the first standards lab quality electronic reference to gain wide acceptance as a replacement for saturated standard cells. Originally designed for internal transfers of Fluke’s corporate volt to the production floor, thousands are now in service worldwide in a variety of applications—from maintaining an institutional reference to transferring values from national labs or privately-operated 10 V Josephson Arrays.

To obtain the best performance, use the Product in controlled environments with good system grounding and shielding practices. For radiated EMI fields from 0.25 to 1 V/m from 80 to 130 MHz, add 9 µV to the 1 V output, and 3.6 µV to the 0.1 V output. For ac mains conducted EMI of 1 Vrms from 75 to 80 MHz, add 1 µV to the 1 V output, and 0.7 µV to the 0.1 V output. The 10 V output is mostly unaffected by EMI fields up to 1 V/m or by conducted EMI up to 1 Vrms.
