Detect AC/DC voltage with Memory HiCorders
The MR9321-01 and MR9321 are 4-channel logic probes used to detect the presence of AC/DC voltage with Hioki Memory HiCorders.
Connects to the logic input terminals of Hioki Memory HiCorders. Check the size of the terminal before purchase.
4 isolated channels in a single probe
• Detect the ON/OFF status of AC100V/200V as well as DC24V signals
• Also convenient for detecting sudden AC power line interruptions
• High speed response of 1ms rise and 2ms drop
• MR9321-01 features a miniature connector, and MR9321 features a larger connector for legacy products
Basic specifications (Accuracy guaranteed for 1 year)
Note: The unit-side plug of the MR9321-01 is different from the MR9321.
