Description
The Tonghui TH2518 is a highly flexible resistance/temperature scanner with a 4.3″ touch TFT LCD and up to 90 parallel measurement channels. It combines precise 4-wire resistance measurement (10 μΩ - 200 kΩ, 0.05 % basic accuracy) with programmable temperature measurement (PT100, PT500, analogue) and offers both stand-alone and scan operation.Features
- 4.3″ 24-bit touch TFT LCD (480 × 272 px) with DE/EN GUI
- Up to 90 scan channels (6 plug-in boards with 15 channels each) with synchronised measurement
- Max. Test speed up to 600 measurements/s (6 boards)
- Resistance measurement 10 µΩ-200 kΩ, auto/manual, ≤ 100 mA measuring current
- Temperature measurement PT100/-500 & analogue 0-2 V with compensation
- Measurement modes: stand-alone & scanning; trigger: internal, manual, external, bus, handler, foot switch
- Data logging, one-click screenshot, software upgrade via USB HOST
- Handler interface, RS232, USB host/device, LAN
