Anritsu Meter HD-1150E / HD-1150K Handheld Thermometer

Overview

The Anritsu Meter HD-1150E / HD-1150K is a high-precision, single-channel handheld thermometer engineered for laboratory, industrial process, and field service applications requiring traceable thermal measurements with minimal operator intervention. Built upon Anritsu’s legacy of metrological rigor, the instrument employs digital linearization compliant with IEC 60584-1:2013 — the international standard governing thermocouple reference functions — ensuring thermoelectric voltage-to-temperature conversion adheres to certified polynomial coefficients for E- and K-type thermocouples. Its core architecture integrates a monolithic reference junction compensator directly into the input terminal block, eliminating external cold-junction drift and enabling stable, repeatable measurements across ambient temperatures from 0 to 40 °C. Designed for robustness in demanding environments, the unit features IPX5-rated ingress protection against water jets, making it suitable for use in humid production floors, HVAC commissioning sites, or outdoor calibration verification tasks where incidental splashing may occur.

Key Features

• High-accuracy thermocouple measurement with dual resolution modes: 0.1 °C within −104.9 to +504.9 °C (E/K), automatically switching to 1 °C resolution outside this span
• Integrated reference junction compensation with ±0.2 °C accuracy at 25 °C ±10 °C, eliminating reliance on external sensors or software correction
• ANP input interface using thermocouple-grade metals at the connector — matching Seebeck coefficient and minimizing parasitic EMF generation
• Backlit LCD display with 300 ms update rate and HOLD function for freezing real-time readings during inspection or documentation
• Low-power design supporting up to 300 hours of continuous operation on four standard AA alkaline cells
• Auto-power-off after five minutes of inactivity to conserve battery life without compromising measurement readiness
• Compact ergonomic form factor (76 × 167 × 36 mm) and lightweight construction (~350 g with batteries) for extended handheld use

Sample Compatibility & Compliance

The HD-1150E / HD-1150K is compatible exclusively with standardized base-metal thermocouples — specifically E-type (chromel–constantan) and K-type (chromel–alumel), with optional variants available for J, T, and R types. Input impedance is optimized for signal sources ≤500 Ω, ensuring compatibility with both industrial-grade and laboratory-calibrated probes. The device meets CE marking requirements under the EU Electromagnetic Compatibility Directive 2014/30/EU and the Restriction of Hazardous Substances Directive 2011/65/EU (RoHS). Its thermocouple linearization algorithm conforms to IEC 60584-1:2013, supporting metrological traceability in ISO/IEC 17025-accredited laboratories. While not explicitly validated for FDA 21 CFR Part 11 compliance (as it lacks user authentication or electronic signature capability), its deterministic behavior, stable calibration, and documented factory test certificate support GLP and GMP-aligned temperature verification protocols when used as a readout device in controlled environments.

Software & Data Management

The HD-1150E / HD-1150K does not feature onboard data logging; however, select higher-tier models in the HD-series (e.g., HD-15xx) provide 9999-point internal memory with programmable intervals (9 selectable settings) and manual trigger capability. For the HD-1150 series, data capture relies on external recording methods — such as manual transcription or integration with third-party DAQ systems via analog output (if equipped). Anritsu provides dedicated PC software for compatible models, enabling CSV export, time-stamped waveform visualization, and batch analysis. All factory units ship with a traceable calibration certificate verifying 0 °C point accuracy within ±0.2 °C, issued per ISO/IEC 17025 requirements. Firmware updates are distributed through Anritsu’s official support portal and require proprietary configuration tools.

Applications

• Verification of oven, furnace, and environmental chamber setpoints in manufacturing QA/QC workflows
• Thermal validation of sterilization cycles (e.g., autoclaves, depyrogenation tunnels) per ISO 17665 and HTM 2030 guidelines
• Field calibration checks of fixed-mount thermocouple transmitters and PLC input modules
• Temperature profiling during electronics reflow soldering process development and troubleshooting
• Energy audit measurements on steam traps, heat exchangers, and HVAC ductwork
• Educational labs requiring stable, low-drift thermocouple readouts for thermodynamics and materials science experiments

FAQ

What thermocouple types are supported by the HD-1150E / HD-1150K?
The standard unit supports E-type and K-type thermocouples. Optional configurations are available for J-, T-, and R-type inputs — contact Anritsu Meter technical support for model-specific availability.
Is the instrument supplied with a calibration certificate?
Yes — each unit ships with a factory-issued test report confirming 0 °C accuracy within ±0.2 °C, traceable to national standards.
Does the HD-1150E / HD-1150K support data logging?
No — data logging is not implemented in the HD-1150 series. For logging functionality, consider the HD-15xx series or integrate with external DAQ hardware.
Can the device be powered by AC adapter?
The HD-1150E / HD-1150K operates solely on four AA alkaline batteries; no AC adapter option is provided in this model variant.
What is the temperature coefficient of accuracy?
The measurement error varies with ambient temperature at ±0.01% of full-scale range per °C deviation from 25 °C, applicable across the operating range of 0–40 °C.
