Product details
Professional Instrument Equipment and Testing Solution Supplier - JETYOO Industrial&Jianyou (Shanghai) Measuring Instrument Co., LtdFounded in 2011 by Jian JET, a product technical support engineer for Agilent (now known as KEYSIGHT), and Rong YOO, a product technical support engineer for KEITHLEY (now known as Tektronix)Characterized by technological applicationsThe agency trading company,Focused on the industrial testing industry for 16 yearsAiming to break through the old and establish the new! Fill the gap of most imported instrument and equipment manufacturers only setting up sales points in China, but with weak or no technical support, and agent distributors only specialize in sales, not professional in pre-sales technical Q&A/testing plans, and not professional in after-sales training/maintenance calibration. oursTechnical salesAll of them have a bachelor's degree or above, and have more than 10 years of experience in the testing industry. With our advanced and unique business philosophy of "relying on technology! Selling instruments!", we specialize in providing instrument equipment, testing solutions, technical training, maintenance and measurement services for Chinese users, serving the industryA company with technical engineersA technology oriented comprehensive service provider for instruments and equipment.
DM7276Japanese Japanese DC voltmeter HIOKI DM7275Performance characteristics
Application covers 7-and-a-half-digit DC voltmeter from research and development to production line
Low price basic model with a 1-year precision of 20ppm [DM7275 model] and a 1-year precision of 9ppm [DM7276 model]
Contact inspection using electrostatic capacitance
Suitable for producing wide power supplies
EXT I/O, LAN, USB standard configuration
The standard accessory does not come with a test probe. Please purchase the probe from the options according to the measurement purpose.
The one-year accuracy of the approximate standard source is 20ppm, exceeding the long-term stability of the standard source
HIOKI, with strong on-site adaptability, is a DC voltage specialized voltmeter that has advantages in accuracy, stability, and price
A resistive touch screen with strong on-site adaptability and rich interfaces
The interface used for operation is a resistive touch screen, which can also be accurately operated using gloves. Standard communication interface that can be flexibly used for computer connection and controller connection
Interference performance of approximate standard source
Due to the installation of a wide power supply, it is possible to simulate and reproduce the same environment in any factory.
The unique suspended structure can approximate the interference performance of the standard source used for calibration.
From research and development to production line, it can be matched, and success is only 1/4 of previous models
High cost-effectiveness and strong anti-interference performance can be applied not only in R&D and quality control departments, but also in production lines.
Basic performance of voltmeter
Due to the high input impedance of the voltmeter, it is easily affected by interference.
In environments with high interference such as production sites, high interference removal or low input bias current are important selection criteria for long-term stable measurement.
Graphic interface, intuitive operation
Equipped with interfaces that consider necessary functions such as voltage trend and statistical display, as well as various usage environments such as comparator and BIN functions that are linked to various measurement screens. Moreover, it can be customized for production sites and can be used as a reliable standard source with strong on-site adaptability.
Application: Measurement of shell potential of lithium batteries
In order to safely and accurately measure the insulation failure inside the thick and heavy layered lithium battery, it is necessary to measure the shell potential.
In insulation resistance tests and withstand voltage tests, cracks in aluminum laminates that do not affect the characteristics are detected, and in the worst case, the electrolyte may decompose.
Because only voltage measurement is performed, the contact inspection function can be safely used to accurately identify any faulty conditions.
Application transition feature monitoring
The charging and discharging characteristics of batteries, which are difficult to measure due to interference and masking in typical waveform recording, can easily obtain data.
This is an application that can only be completed by strong interference DC voltage measurement and DM series with high-speed sampling mode.
