MR8847A
Hioki
Memory HiCorder
High-speed 20 MS/s (*1), 32-channel, Fully Isolated Memory Recorder for On-site Jobs and R&D
Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple physical phenomena such as voltage, current, temperature, vibration, acceleration and rotation due to complete isolation between channels and from each channel to the ground. The MR8847A delivers 20 MS/s sampling (*1), 32 isolated channels, and max. 1000 V direct input, all housed in a tough and field-ready body to properly respond to the most challenging work sites from transformer substations to railway maintenance yards to paper and steel mills.
Key Features
- Supports a wide variety of measurements with a total of 17 plug-in modules
- Generate and record with a single unit
- Direct 1000 V high voltage input testing
- High-speed sampling up to 20MS/s (*1) with fully isolated inputs
- 32 analogue channels + 16 logic ch to 20 analogue channels + 64 logic ch
- High-speed sampling with waveform judgement function
- Soil-resistant construction strong against adverse working environments
- Big buttons coated to withstand industrial oil and residue
- Drop-in paper loading and one-touch setup, along with high-speed 50mm/s printing
*1: When U8975, U8977, U8978 are installed, max. sampling speed is 10 MS/s.
