DELTA OHM - Model HD2010UC/A - Integrating Sound Level Meter Frequency Analyzer

The HD2010UC is an integrating portable sound level meter performing statistical analyses. The instrument has been designed combining price competitiveness and simplicity of use. Attention has been paid to the possibility of updating the instrument, and the HD2010UC can be integrated, at any time, with other options to extend its application scope. The firmware can be upgraded directly by the user using the DeltaLog5 program supplied with the instrument.

DELTA OHM - Model HD 2030 - Four Channel Vibration Analyzer

The HD2030 is a portable 4 channel vibration analyzer able to perform spectral and statistical analysis. The instrument can supply all the measurement parameters required by the current normative concerning the operators protection from the risk connected with the vibrations and is able to measure in hand-arm and whole body modes. It is also possible to determine the vibrations transmitted to a person through the buildings. The HD2030 vibration analyzer detects accelerations on four axes through two accelerometers with integrated amplifying electronics (IEPE or equivalent type). Three axes are grouped in the right input, where it is possible to connect three accelerometers or a tri-axial one; the fourth axis is associated to left input.

DELTA OHM - Model HD 2070 - Three Channel Vibration Analyzer

Three channel vibration analyzer HD2070 is a portable vibration analyzer performing spectral and statistical analysis on three channels simultaneously. The instrument measures all parameters required by current regulations concerning workers protection from vibration related risks and is able to measure vibrations transmitted to both hand-arm and whole body. It has been designed combining simplicity of use with maximum flexibility and the possibility of updating the instrument according to the evolution of the regulations relating to vibration measurement. The firmware can be updated directly by the user by means of the Noise Studio program supplied with the instrument. Technical standards HD2070 vibration analyzer conforms to the following standards: • ISO 8041:2005 “Human response to vibration Measuring instrumentation” • ISO 5349-1:2001 “Mechanical vibration Measurement and evaluation of human exposure to hand-transmitted vibration – General requirements”

DELTA OHM - Model HD2110L - Integrating Sound Level Meter - Portable Analyzer

HD 2110L Integrating Sound Level Meter - Portable Analyzer the HD2110L is a precision integrating portable sound level meter, with data logging functions, performing both spectrum and statistical analysis. The instrument has been designed in order to offer high-performance analysis of acoustic phenomena. Attention has been paid to the possibility of adjusting the instrument to regulatory modifications and to the necessity of meeting its users’ needs of today and tomorrow. The HD2110L can be integrated with other options to extend its application scope at any time; the firmware can be updated directly by the user by means of the Noise Studio program supplied with the instrument. Technical regulations: ü Class 1 sound level meter according to IEC 61672-1, 2002 (Certificate of Compliance I.E.N. No. 37035-01C), IEC 60651 and IEC 60804. ü Class 1 octave and third octave filters according to IEC 61260 ü Microphone in compliance with IEC 61094-4

Delta OHM - Model HD2022 - 2nd class Acoustic Calibrator

The HD2022 sound level calibrator is a portable, battery operated sound source, suitable for sound level meters and acoustic stations. It allows calibrating ½” and ¼” microphones with mechanical dimensions compliant with IEC 61094-1 (“Measurement microphones. Part 1: Specifications for laboratory standard microphones”) and IEC 61094-4 (“Measurement microphones. Part 4: Specifications for working standard microphones”). The generated sound pressure level is equal to 114 dB at 1000 Hz frequency. A LED signals the low battery condition. The HD2022 can be calibrated by a Delta Ohm authorized dealer or laboratories accredited for calibration of sound level generators. Calibrating the instrument means checking that frequency, sound level and signal distortion fall within the limits of tolerance set by the reference standard (IEC 60942:2003).

DeltaOHM - Model HD2060 - Vibration Acelerometer Calibrator

The calibrator HD2060 generates mechanical vibration amplitude controlled with precision and frequency stabilized by a quartz. Coupling a transducer to the vibrating base of the calibrator it is possible to check its sensitivity to acceleration, velocity or displacement. The presence of a rechargeable internal battery, the weight and the small dimensions as well as the low sensitivity to environmental parameters make it easy to use the calibrator in the field. The calibrator is equipped with a feedback system capable of accurately maintaining the amplitude level set, regardless of the load associated with the mass of the transducer (within the limits stated in the technical specifications). The mechanical vibrations generated by the calibrator are very stable over the time, with a typical drift of 1% per year.Two frequencies of solicitation: 15,915 Hz at 1 m/s2 and 0,1 g 159,155 Hz at 10 m/s2 and 1 g Low distortion accelerations, independent from the mass of the transducer
