DTF-MU Triple Point of Water Maintenance Bath (Electrical Testing Version)

Product Characteristics

Full-Category Sensor Compatibility
Standard Input: Independent channel;supports 1st/2nd grade SPRTs (Pt25/Pt100), smart sensors (RTD/SMP), and S/R/B/T TCs. Temp control and reference measurement run independently.
DUT Coverage: RTDs (Pt/Cu), TCs (S/R/B/K/N/E/J/T), Transmitters(Voltage, current), Temp Switches, Oil/Winding Controllers, Pressure/Dual-metal Thermometers.

Lifecycle Mgmt
Full CRUD functions. Auto formula matching for SPRT/RTC. Plug-and-play with auto-import & highlighting.

Integrated Core Hardware
High-Precision Electrical Measurement: 6½/7½ digit (optional) for Ω, DCV, DCI. Resolution down to 0.0000001℃.
Deep Integration: Hardware + algorithm fusion (not simple stacking) eliminates multi-device errors.
4-Wire RTD Reversal: Separates excitation & high-impedance detection to eliminate lead/contact resistance.
Patented CJC: Independent high-precision cold junction sensor with multi-point monitoring & smart compensation.
Basic Capabilities: Gain/zero calibration, filtering, one-click zeroing, customizable standard criteria.

Fully Automated Workflow
Visual Task Config: One-click multi-point self-correction. Parallel DUTs (up to 8). Switch testing (up to 6) with custom ramp rates. Auto tolerance matching based on accuracy class.
Real-time Monitoring: Live data, progress, countdown, and 10-min fluctuation graphs. Auto-highlight for out-of-tolerance.
Programmatic Data Processing: Built-in JJG algorithms (229/141/351/630). Auto-calculates errors, judges compliance, and exports traceable raw data.

Intelligent Control & Acquisition
Programmable Ramp: Multi-point programming with auto rate control.
Adaptive PID: Auto-tuning based on load/media for optimal control.
Procedure-level Stability: Triggers data acquisition only when strictly meeting regulation criteria.
Multi-Channel Sync: Auto scans all channels, syncs bath/DUT data, and averages forward/reverse readings.

Data Management & Security
Massive Storage: 8GB capacity for 100,000+ records; multi-condition search.
Backup & Recovery: Custom auto-backup cycles; full or single-record recovery.
Security & Continuity: Tiered access control, anti-tamper logs, and auto-resume after power outage.
Remote Diagnostics: Full operation logs exportable for remote troubleshooting.

HMI & Expansion
Display: 5/7-inch HD touchscreen with intuitive GUI.
Connectivity: RS232/RS485, WiFi, LAN, USB for data export.
Sustainable Upgrade: USB firmware updates for ongoing compliance and feature upgrades.
