Fluke 2638A Hydra Series III Data Acquisition System with 66 Universal Inputs 6.5-Digit DMM and IEC Category II 300V Safety
The Fluke 2638A Hydra Series III is a high-performance data acquisition system and digital multimeter combination designed for precision measurement and data logging applications in industrial environments.
- ACCURATE: DC accuracy of 0.0024% and thermocouple accuracy of 0.5°C
- EXPANDABLE CHANNELS: Up to 66 universal differential isolated inputs, 20 on-board math channels, 45 channels/second basic DC scan rate
- SELECTABLE INPUTS: AC V, DC V, AC I, DC I, thermocouple, PRT (2, 3, 4 wire), thermistor, resistance (2-4 wire), frequency
- DIGITAL MULTIMETER MODE: 6.5-digit bench DMM function for front panel inputs
- ONE-BUTTON SCREEN CAPTURE: For chart or data displays, color trend graphing and analysis
- MULTI-CHANNEL REAL-TIME DATA: Monitor function for real-time viewing and charting between scans
- MEMORY AND DATA: Internal 75,000 scan/setup file memory, USB flash drive support, data security features
- SAFETY RATING: Only general purpose portable data acquisition system with an IEC Category II 300 V safety rating
Accuracy specifications generally are valid for 6.5 digit resolution mode (unless otherwise noted) after a minimum of one-hour warm-up, and within an operating temperature range of 18°C to 28°C. Derating applies with a fast sample rate and for operating temperatures outside the limited range.
Twenty-four-hour specifications are relative to calibration standards and assume a controlled electromagnetic environment per EN 61326. The confidence level for accuracy specifications is 95% within one year of calibration (unless otherwise noted).
