Simply and accurately assess and capture noise dose and the true noise exposure of workers using the Pulsar Personal Noise Dosemeter System. The UK Health and Safety Executive (HSE) recommends that employers should obtain a reliable estimate of employees' exposures, and compare the exposure with the exposure action values and limit values. This dosimeter badge system is just the device to do this. 

  • The revolutionary dosimeter badge is a self-contained noise measurement device, also known as Personal Sound Exposure Meter (PSEM), that has no cables, displays or controls, making it the perfect solution for noise dosimetry, because units cannot be tampered with easily or damaged during measurements.
  • A separate Decibel Reader unit communicates with the dosemeters and controls the programming, calibration, start-stopping, data logging, downloading and storing of measurements. All key measurement parameters can be viewed on its large clear back lit LCD display screen, which also displays a time history graph of worker's daily noise exposure over an entire working day.
  • The Reader contains an integral acoustic calibrator allowing the dosemeter to be calibrated prior to and following each noise measurement in accordance with international regulations; the dosemeter automatically achieves this by computing the Daily Exposure for European legislation or the Time Weighted Average for US-based legislation.
  • Full ‘Time History’ information allows you to determine when key noise problems occur during a worker's day.
  • Collect all the data essential to meet compliance with occupational noise regulations at the touch of a button including LAeq, LEP,d, % Dose and TWA. 
  • Frequency weightings include 'A' weighted (range 70dB(A) to 130dB(A)). The additional ‘C’ frequency weighted peak Time History allows you to fully assess risks from impulsive noise in the workplace.
  • Our effective, user-friendly software package, AnalyzerPlus, allows users to quickly analyse and transform the raw data into informative report formats, simplifying a potentially complex and time-consuming process.

Pulsar Software

The Model 22 dosemeter system is supplied as standard with our easy to use AnalyzerPlus program. To assist new users, a step by step wizard reassuringly guides you throughout the set-up and download procedures and allows measurement data to be viewed, analysed and printed.

Pre-formatted report templates are provided to present your measurement data. These reports can be printed or exported into a number of formats including Word, Excel and PDF.

The fact that AnalyzerPlus have no licensing restrictions means the user is able to install the software onto multiple computers and laptops eliminating hidden costs and optimising user flexibility.


Each dosemeter noise measurement system is supplied with everything required to conduct a fully compliant noise survey.

Contained in each system is the: 

  • Model 22 noise dosimeter(s) & leather mounting kit(s)
  • Model 22-R Reader unit with integral acoustic calibrator
  • CHR20-*D Charger unit for 2, 5 or 10 dosebadges
  • K3 Hard Attaché Case
  • Power supply
  • AnalyzerPlus download, analysis and reporting software
  • Batteries
  • USB download cable
  • Calibration certificates
  • User manual
  • 2-year warranty

Optional Accessories:

  • WS22 protective windshields to protect against dust, moisture and noise generated by 'spurious' events
  • RK1 Key-fob remote control
  • Helmet mounts


  • Model 22 noise dosemeter: 45gms (1.6oz)
  • Model 22-R Reader: 400gms (14oz)

Why not combine the Pulsar Model 22 dosemeter system with a Sound Level Meter and Acoustic Calibrator?

The hard kit case supplied for your dosemeter system has space for 5 individual dosemeters along with all of the standard accessories.

The dosemeter system kit case allows enough space for any combination of our Sound Level Meters such as the Pulsar Nova Model 44 Noise at Work Meter, an Acoustic Calibrator and a windshield. This allows the dosemeter kit to be transformed and adapted into a Safety Professional kit to provide you with a complete noise monitoring solution.

We purchased a Pulsar doseBadge and supporting instrumentation last year along with a familiarisation Noise Awareness training day. The equipment is certainly robust, unobtrusive and ‘user friendly' and provides a real time analysis of workplace noise. The noise measuring equipment and service furnished by Pulsar Instruments plc has proved to be first class and I would provide an unequivocal recommendation to anyone considering the introduction of this noise management hardware/software. Some of the credit for the Company award of OHSAS 18001 accreditation last year must be directed at Pulsar due to the favourable observations made by the external auditor on the management of noise at work. Thank you for your impartial guidance and advice and for providing a cost effective system which proves beyond any doubt that we can defend any allegations of poor workplace noise management.

Pulsar Model 22 noise dosebadge system is an all singing, all dancing system that is genuinely robust and does exactly as promised. I am happy to endorse this product for any environment where one would allow people to work.
English National Opera
The subject of the long term effects of noise for performing arts professionals has always been sensitive and difficult to assess. At English National Opera, we have been very aware of this situation and in 2004 decided we needed arobust, reliable and unobtrusive system that would allow us to gain a greater understanding of the typical personal noise exposure levels received by members of our orchestra, chorus, stage performers, technicians and other staff. Given that the music and performance dynamics change from production to production, we needed to incorporate these differences into our noise control plan. We invested in the Pulsar Instruments Plc Model 22 doseBadge system that consists of small, robust and lightweight dosimetry units that attach comfortably to the shoulder of the employee being monitored. After each session this information is then communicated to the reader unit where we can easily view the essential measurement information. We then have the option of downloading each group of measurements to a computer for further analysis and reporting. The time histories of the noise levels are very useful for determining when the main exposure levels occur and which members of staff are most affected. This method of capturing data has provided us with valuable information enabling us to assess and then investigate ways of minimising the risks from noise exposure. When routine verification of the equipment is required we simply contact Pulsar Instruments to arrange the prompt service and recalibration our doseBadge system.
