Bruel & Kjaer 2250-D-D00 Hand-Held Analyzer
Overview
The Bruel & Kjaer 2250-D-D00 is a hand-held analyzer from the 2250 series, a Class 1 portable sound level meter built for workplace and environmental noise assessment. The instrument combines sound level metering with frequency analysis in a single battery-powered unit, making it the standard tool for industrial compliance testing, occupational noise surveys and environmental measurements. The D-D00 suffix identifies the order code of the analyzer configuration supplied.
The 2250 series has become the reference instrument for noise assessment in many countries, supported by the B&K documentation, calibration and service network. The order code D-D00 fixes the configuration at the factory, so the instrument arrives ready for the measurement tasks it was specified for. Seven Star LLC supplies the 2250 with the accessories and calibration documentation needed for a compliant measurement programme.
Engineering and Design
The 2250 is a Class 1 instrument, meaning it meets the IEC 61672-1 requirements for precision sound level meters. It measures broadband sound pressure levels and supports frequency analysis for noise identification, with the results shown on the instrument display and stored for later reporting. The hand-held form factor with a single microphone input keeps the instrument practical for field surveys, while the software environment allows the same platform to be extended with additional measurement applications.
For a workplace noise survey, the meter is calibrated with the acoustic calibrator before and after the measurement series, then held at the measurement position for the required interval. The stored results are downloaded to the PC software for reporting and archiving. For environmental measurements, the instrument is mounted on a tripod with a windshield and left to log over the measurement period, giving the Lp, Leq and statistical levels required by the survey standard.
For a workplace noise survey, the meter is calibrated with the acoustic calibrator before and after the measurement series, then held at the measurement position for the required interval. The stored results are downloaded to the PC software for reporting and archiving, and the same data can be exported for the assessment report. For environmental measurements, the instrument is mounted on a tripod with a windshield and left to log over the measurement period, giving the statistical levels required by the survey standard. Battery life and memory capacity are checked before the measurement series, and the calibrator certificate is kept with the measurement records. The instrument menu guides the operator through the measurement setup, and the most recent configuration is retained after power off. Training and demonstration units are available for teams adopting the 2250 for the first time. The 2250 display shows the active measurement together with the battery and memory status, and the backlight is adjustable for outdoor use. The instrument is protected by a rugged carrying case for transport between survey locations.

Why Seven Star LLC
Seven Star LLC supplies Bruel & Kjaer acoustic measurement instruments and accessories to EHS, laboratory and maintenance programmes across Oman and the GCC. Every instrument is verified against the original B&K product and order code before your order is confirmed, and our team helps you select the correct configuration for your noise survey standard.
Technical Specifications
This unit is based on the Brüel & Kjær (HBK) Type 2250 fourth-generation hand-held sound and vibration analyzer platform. The exact “-D-D00” ordering suffix on this listing does not appear in B&K’s own published Type 2250/2270 ordering nomenclature (which documents 2250-S, 2250-S-C, and 2250-W variants), so Seven Star LLC confirms the exact configuration and accessory bundle directly against the customer’s requirement rather than assuming a specific meaning for this suffix.
Based on the documented Type 2250 platform specifications, the analyzer covers a frequency range of 0.5Hz to 20kHz (broadband linear) with a dynamic range exceeding 123dB(A), and complies with IEC 61672-1 (2013) Class 1 and ANSI/ASA S1.4-2014 Class 1 accuracy standards. It supports A, B, C, and Z frequency weightings alongside F, S, and I time weightings, and features a 240×320 touch color display with USB 2.0, LAN (RJ45), and optional Wi-Fi/4G connectivity for remote data access and reporting.
Applications
The Type 2250 platform is used for environmental and occupational noise assessment, building acoustics testing, product noise quality-control measurement, and general vibration and infrasound analysis — a genuinely multi-purpose instrument that consultancies, industrial safety teams, and acoustic testing labs across Oman and the GCC rely on for both compliance measurements and engineering diagnostics from a single handheld unit.
Standards and Why Seven Star LLC
The platform complies with IEC 61672-1, IEC 61260, IEC 60651/60804, and ANSI S1.4/S1.11. Seven Star LLC supplies genuine Brüel & Kjær acoustic and vibration instrumentation, including the Type 2250 analyzer family, to consultancies and industrial safety teams across Oman and the wider GCC, and confirms the exact accessory bundle, calibration certificate, and software module configuration required before confirming an order.
