James Durrans Group –
I would like to commend โPulsar Instrumentsโ on the excellent and timely service we at James Durrans have received. Since we first purchased our noise monitoring equipment in 2013, then subsequent upgrade of our Model 44 sound level meter, and calibration service is quick, reliable and efficient collecting and returning by courier [for an additional cost but worthwhile.] The equipment is sturdy and easily understood, and you donโt need to be a computer whiz to operate the software.

DHL –
I purchased my noise meter last year from Pulsar Instruments and has proven to be an excellent tool. As it was coming close to its first year anniversary, I received a reminder in the post that it would need its annual calibration check with more than sufficient notice. The instructions for returning my meter were very simple and it was duly sent away. My noise meter was returned very quickly and without any problems. Overall I cannot fault the service I have received from Pulsar.

Sidhill Ltd –
Sidhil Ltd is a well established manufacturer and supplier of furniture and accessories for the healthcare market. The company has 7 sites across the UK where fabrication takes place. The HR and HS Manager was keen to take control of the noise risk assessment process and undertake noise measurements at a time to suit her requirements. When it came to invest in a new piece of noise measurement equipment, she chose the Pulsar Nova Model 44K professional noise measurement kit. “We were impressed with the product presentation and, clearly, it was the right solution to help us carry our internal audits and comply with the Noise at Work Regulations”.
Charles Wilson Engineers Limited –
We made the decision to purchase one of Pulsar Instruments Nova Model 44 Class 2 test meters with data logging a very easy one indeed. The sales advice I received was truly excellent. You really felt that there was someone at the end of the telephone who understood our requirements and had the correct product to satisfy them. The Nova noise meter is a brilliantly engineered piece of equipment that is very easy to use and it interfaces superbly with the excellent data logging software.
Donwell Group –
Working for a demolition company, we are requested to carry out environmental monitoring more and more. I came across the Pulsar Instruments’ website and saw their product range so decided to find out more. I was asked a series of questions to assess which instrument was most suitable for my needs which turned out not to be the most expensive. After delivery, I was contacted to ask if there were any issues (which there weren’t). I did have a couple of questions once I started using the supplied software – which is great – my questions were answered immediately and explained in a way I could understand. Overall a 5 star rating for both the instrument itself and the service too. Testimonial from SHEQ Manager

I have been most impressed with my dealings with Pulsar Instruments. From my very first call, where we discussed the merits of the various options you would be able to offer me, to the valuable insights you shared with me during your visit of my premises to understand exactly the nature of our business, and the specific challenges we face with regard to noise exposure in some of our processes. As a Manager with responsibility for the health and safety of my team, yet little experience in the noise monitoring field, finding and exploiting your knowledge and awareness has helped me to make a good choice for our business that will both keep my people safe, and ensure that the business remains compliant even as our processes and factory layouts evolve.
I am delighted that I am now able to make my own assessments with a piece of equipment that I can trust, and one that will be recognised by industry professionals. You know from our discussions, that I have placed a high priority on being able to ensure that any reports I generate are able to stand up to even the most intense scrutiny, the integrity of your device clearly delivers this level of probity.
I have been working my way through the software, and again I am finding it easy to understand and use despite my lack of experience. I particularly like being able to demonstrate that my instrument has been calibrated both before and after any monitoring period. Any reports saved directly as PDFโs cannot be challenged as having been corrupted either deliberately or accidentally.
I am very much looking forward to attending the one day Noise Awareness Training course, and I hope to bring some questions that will help me to really get the best out of my new investment.
Please convey my thanks to your staff for their efficient administration. I received the quotation I asked you for within an hour of you leaving for your long journey home, and I was kept fully briefed on progress, even providing a tracking number once the package had been despatched.
All in all, a first class effort from everyone at Pulsar Instruments.
