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.

Suitable for installation in automatic equipment and building simple MLCC leakage current inspection lines
Test probes are not standard. Please purchase additional probes from the options according to the testing purpose.
The 4CH model of SM7120 with 20P Ω measurement is introduced
The 4CH model, which retains the anti-interference and measurement functions of SM7120 and specializes in measuring small currents, has been newly launched. This is a high-speed model suitable for assembly into automated equipment, such as batch production inspection for MLCC inspection.
Leather safety gauge equipped with contact inspection function
Comes standard with contact check function.
By using a small current measurement function in combination with an external power source, contact inspection can be achieved, so it can be used with confidence during assembly. No need to make too many attempts, improve the overall working hours. 4 channels can be checked separately, and the frequency and delay time can be set, so it is possible to make subtle adjustments that comply with the production line design.
