Introduction

This product is a full-range temperature metrology and calibration platform integrating high-precision electrical measurement, intelligent temperature-field control and fully automated workflows. It is specially designed for the automatic verification and calibration of temperature sensors, transmitters and temperature switches. By deeply integrating the constant temperature field generation unit and high-precision electrical measurement unit, it eliminates additional errors caused by the combination of multiple discrete devices, and delivers reliable, efficient calibration solutions for metrology labs and industrial sites.

Product Characteristics

1. 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.

2. Lifecycle Mgmt:

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

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.
