Thermo Scientific Temp 360 High-Precision RTD Thermometer

Overview

The Thermo Scientific Temp 360 High-Precision RTD Thermometer is an engineered solution for traceable, stable, and repeatable temperature measurement across demanding industrial, laboratory, and field environments. Built upon platinum resistance temperature detector (RTD) technology—specifically a Class A Pt100 sensor—the instrument delivers metrological-grade accuracy aligned with IEC 60751 and ASTM E1137 standards. Its measurement principle relies on the predictable, nearly linear change in electrical resistance of high-purity platinum wire as a function of temperature, enabling superior long-term stability and minimal drift compared to thermocouple-based alternatives. Designed for versatility, the Temp 360 supports single-channel input via standardized 3-pin connector, accommodating interchangeable probes for immersion in liquids, surface contact, air/gas stream monitoring, and semi-solid matrix applications. With an extended operating range from –201 °C to 1210 °C and resolution as fine as 0.01 °C in the critical –99.99 °C to 99.99 °C interval, it meets stringent requirements in calibration labs, pharmaceutical manufacturing, food safety QA/QC, HVAC commissioning, and thermal process validation.

Key Features

• Class A Pt100 RTD input with full-range accuracy compliance per IEC 60751: ±0.03 °C at 0 °C, ±0.1 °C up to 100 °C, and ±1 °C above 1000 °C
• Large 58 × 40 mm backlit LCD display with high-contrast numeric rendering for rapid visual verification under low-light or outdoor conditions
• 2000-point internal data logger supporting programmable storage intervals from 1 second to 60 minutes—or manual capture via dedicated keypress
• Three ergonomic hands-free mounting options: magnetic base for ferrous surfaces, pipe/hose clamp attachment, and integrated fold-out stand for benchtop use
• Ruggedized housing constructed from ABS polymer with IP54-rated ingress protection (dust-protected, splash-resistant), sealed keypad, and optional shock-absorbing rubber boot
• USB 2.0 interface compliant with CDC class drivers for seamless data export to Windows/macOS platforms without proprietary software installation
• Auto-hold and min/max/delta-temperature functions with real-time stability indication for reliable endpoint detection during thermal equilibration
• User-configurable auto-power-off (default 17.5 minutes), low-battery indicator, and >750 hours of continuous operation on three AA alkaline cells (backlight off)

Sample Compatibility & Compliance

The Temp 360 interfaces with a broad portfolio of Thermo Scientific RTD probes—including penetration, surface, immersion, and air-sensing variants—ensuring method-appropriate thermal coupling across heterogeneous media. It is validated for use in GLP-compliant laboratories and supports audit-ready workflows through timestamped data logging and non-volatile memory retention. The device conforms to EN 61326-1:2013+A1:2016 (EMC requirements for laboratory equipment) and carries CE marking. While not intrinsically safe, its design adheres to general-purpose industrial safety guidelines (IEC 61010-1). For regulated environments, raw CSV data exports facilitate integration into LIMS or electronic lab notebooks (ELN) and support retrospective review per FDA 21 CFR Part 11 when paired with appropriate IT controls.

Software & Data Management

Data retrieval is performed via standard USB serial communication using vendor-neutral protocols. Exported files are plain-text CSV format with columns for timestamp (YYYY-MM-DD HH:MM:SS), measured temperature (°C), probe ID (if encoded), and status flags (e.g., “Stable”, “Min”, “Max”). No proprietary runtime or license is required; files open natively in Excel, Python Pandas, MATLAB, or statistical analysis suites. Firmware updates—delivered as signed HEX binaries—are applied via the same USB interface and include version-locked checksum verification. Audit trail metadata (e.g., last calibration date, user ID if configured via external system) is maintained externally, consistent with ISO/IEC 17025 Clause 7.7 requirements for measurement traceability.

Applications

• Pharmaceutical: Sterilization cycle mapping (autoclaves, depyrogenation tunnels), environmental chamber qualification, and USP temperature uniformity testing
• Food & Beverage: Cold chain monitoring, pasteurization validation (e.g., 72 °C for 15 sec), and HACCP-critical control point verification
• Chemical Process Industry: Reactor jacket temperature profiling, distillation column tray monitoring, and catalyst bed thermal gradient assessment
• Academic & Research Labs: Cryogenic experiment tracking (down to –201 °C), high-temperature materials testing (up to 1210 °C), and inter-laboratory comparison studies
• Facilities Management: HVAC duct static pressure–temperature correlation, chiller plant efficiency audits, and boiler feedwater temperature trending

FAQ

What RTD probe types are compatible with the Temp 360?
The instrument accepts standard 3-wire Pt100 RTD probes with mini-DIN or screw-terminal 3-pin connectors meeting IEC 60751 wiring conventions. Thermo Scientific P series (e.g., P-100-1A, P-200-SF) and third-party probes certified to Class A tolerance are fully supported.
Does the Temp 360 support two-point calibration in-field?
Yes—users may perform single-point offset adjustment or dual-point calibration using NIST-traceable reference sources (e.g., dry-block calibrators or precision baths) directly through the front-panel menu without service tools.
Is the data logger compliant with 21 CFR Part 11 requirements?
The device itself does not provide electronic signatures or role-based access control; however, its immutable timestamped CSV output serves as raw data suitable for Part 11-compliant systems when imported into validated software with appropriate procedural controls.
Can the Temp 360 operate continuously while connected to USB power?
No—it draws power exclusively from internal AA batteries. USB connection is data-only; no bus power is accepted or utilized.
What is the recommended recalibration interval?
Thermo Fisher recommends annual calibration against accredited standards, or prior to critical measurements, in accordance with ISO/IEC 17025 and internal quality procedures. Calibration certificates are issued with documented uncertainty budgets.
