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.

Japanese HIOKI MR8740 RecorderPerformance characteristics

Recorder for high-speed, insulation, and multi-channel testing systems (rack assembled type)

The 24 bit high-resolution digital voltmeter unit MR8990 is newly launched! High speed and high-precision measurement can be achieved without the need for a scanner.

Suitable for multi-channel testing (MR8740:54ch, MR8741:16ch)

Insulation input (insulation between input channels and enclosures: maximum rated voltage to ground AC, DC300V)

High speed sampling (maximum 20MS/s, 54ch type maximum 32ch simultaneous sampling)

Suitable for assembly in a rack (within 4U · 180mm in height, without display screen, rectangular)

Remote measurement through LAN communication (data transfer to memory, computer operation at a distance from the measurement location)
