Xiatech T1000 Series Multi-Channel Precision Temperature Scanner

Overview

The Xiatech T1000 Series Multi-Channel Precision Temperature Scanner is an engineered solution for high-accuracy, multi-point temperature monitoring in metrology laboratories, material science research, cryogenic testing, and thermal calibration workflows. Based on the fundamental principle of resistance thermometry—measuring the electrical resistance of platinum-based RTDs (e.g., Pt100, Pt1000) and converting it to temperature using the internationally accepted International Temperature Scale of 1990 (ITS-90)—the T1000 Series delivers traceable, reproducible measurements across an exceptionally wide range from −200 °C to +850 °C. Its architecture integrates low-noise analog front-end circuitry, 24-bit delta-sigma ADCs, and four-wire (Kelvin) sensing to eliminate lead resistance errors—ensuring that accuracy specifications (±0.01 °C) are maintained across the full span without interpolation or external correction tables. Designed for environments where thermal stability and long-term repeatability are critical—including ISO/IEC 17025-accredited calibration labs—the system operates with a documented stability of ±3 mK over 15 minutes and an annual drift of less than 5 mK/year, supporting rigorous uncertainty budgets required by national metrology institutes and industrial QA departments.

Key Features

• 10 independent, isolated measurement channels with simultaneous sampling and synchronized timestamping
• 0.001 °C (0.1 mK) digital resolution and full-scale accuracy of ±0.01 °C referenced to ITS-90
• 7-inch capacitive touchscreen interface with intuitive, icon-driven navigation—no specialized training required
• Built-in ITS-90 polynomial engine enabling real-time conversion from resistance (Ω) to temperature (°C/°F/K) without external software or manual lookup
• Four-wire RTD support with automatic lead compensation and configurable excitation current (0.1–1 mA)
• Onboard data logging (up to 1 million readings) with time-stamped CSV export via USB mass storage mode
• Rugged aluminum chassis and thermally stable internal reference resistors minimize environmental drift

Sample Compatibility & Compliance

The T1000 Series is compatible with standard industrial and laboratory-grade platinum resistance thermometers (PRTs), including DIN/IEC 60751 Class A and AA sensors, as well as custom-calibrated probes with resistance ranges from 0 to 400 Ω. It supports both fixed-point cell verification (e.g., triple-point of water, gallium melt) and continuous process monitoring under GLP and GMP-aligned workflows. The instrument conforms to electromagnetic compatibility requirements per IEC 61326-1 (industrial environment), and its measurement traceability aligns with ISO/IEC 17025 clause 6.5.2 for equipment calibration. While not FDA 21 CFR Part 11–certified out-of-the-box, audit-ready data logs—including operator ID, timestamp, channel metadata, and raw resistance values—can be integrated into validated systems with appropriate procedural controls.

Software & Data Management

No proprietary runtime installation is required: the T1000 functions as a USB Human Interface Device (HID) and mass storage class peripheral. Raw measurement data exports directly to CSV format with millisecond-resolution timestamps, channel identifiers, and unit-tagged columns (°C, Ω, etc.). For advanced analysis, Xiatech provides optional Windows-compatible SDK (C/C++, .NET, Python) supporting real-time streaming, remote configuration, and script-triggered calibration sequences. All firmware updates are delivered via signed binary packages with SHA-256 checksum validation. Internal non-volatile memory retains calibration coefficients and user-defined probe mappings—even after power cycling—ensuring continuity across shift changes and multi-user deployments.

Applications

• Thermal validation of environmental chambers, autoclaves, and stability test cabinets (per ICH Q5C, USP )
• Cryogenic characterization of superconductors, quantum devices, and low-temperature materials
• Calibration of secondary temperature standards against fixed points or reference PRTs
• In-process monitoring during heat treatment, sintering, and semiconductor wafer annealing
• Multi-zone temperature profiling in bioreactors, incubators, and pharmaceutical manufacturing suites
• Research-grade thermophysical property measurements (e.g., thermal conductivity, specific heat) requiring synchronized spatial-temporal data

FAQ

Does the T1000 Series support two-wire or three-wire RTD connections?
Yes—it auto-detects wiring configuration and applies appropriate compensation algorithms; however, four-wire connection is recommended for highest accuracy.
Can the device be used in vacuum or inert-gas glovebox environments?
The main unit is rated for ambient operation only (0–40 °C, ≤65% RH); probe cabling and sensor selection must be independently qualified for such enclosures.
Is ITS-90 implementation traceable to NIST or other NMIs?
The embedded ITS-90 algorithm implements the official 1990 scale coefficients published by CCT (Consultative Committee for Thermometry); users may load NIST-traceable probe-specific calibration files to extend traceability.
What is the maximum cable length supported between the T1000 and RTD probes?
For optimal noise immunity and lead resistance rejection, Xiatech recommends ≤10 m for shielded, twisted-pair cabling; longer runs require site-specific EMI assessment.
How often does the instrument require recalibration?
Annual verification against a certified reference thermometer is advised; stability performance (<5 mK/year drift) supports extended recalibration intervals under controlled lab conditions per ISO/IEC 17025 Clause 6.6.
