HT3544-12H/24H/2H Multi-channel Resistance Tester
outstanding in anti-interference performance, suitable for supporting automation equipment to complete automatic tes
Overview
The HT3544 multi-channel resistance tester is a new generation product from Hopetech Technology. Each model has two-wire and four-wire switchable modes. They realize maximum two-wire 48-channel resistance test and four-wire 24- channel resistance test. Based on the identical circuit design of the classic model HT3544 resistance meter, HT3544-12 and HT3544-24 is outstanding in anti-interference performance, make it very suitable for supporting automation equipment to complete automatic test.
- Offering 0.02% basic accuracy, 0.1μΩminimum resolution, 1A maximum test current
- With measurable range 0. 1μΩ~3.3MΩ.
- Anti-interference measurement is achieved by protecting the probe used by the port and increasing the test current.
- Using the sorting indicator (option) with loud volume sound to accurately judge whether it is qualified or not at the production site.
- Equipped with RS232/RS485/LANinterfaces and EXT I/O port, HT3544 multi-channel resistance meter is especially suitable for supporting ATE line to complete automatic test.
