It’s one thing claiming to design, develop and manufacture the world’s most accurate, easy to maintain, and best value wearable dust monitoring device – which we do.

But substantiating that claim?

Backing it up with the facts, with independent verifiable research? Field testing our device and comparing it like-for-like with other similar products to prove our point – is that even possible?

It certainly is.

We can prove that the XD One is the world’s leading wearable dust monitoring system.

Courtesy of The HSE – a completely independent UK Government compliance body and one of the leading organisations of its type in the world – who recently completed a series of dust monitoring tests.

Their tests compared three XD One units (to capture a reliable spread of results) with three other commercially available personal dust monitors. 

  • The Casella CEL-712 Microdust Pro
  • The ThermoScientific MIE Personal DataRam (pDR) 1500
  • The TSI SidePak AM510

To measure the mean respirable and inhalable dust concentrations, two gravimetric samplers were also tested against the Trolex XD One – The GK 2.69 cyclone (BGI by Mesa Labs) and the IOM inhalable sampler (SKC Inc.).

Using Arizona Road Dust, the preferred type of dust for dust monitor trials, testing was undertaken in a 1m x 1m x 3m calm air chamber, at three different dust concentrations – low 2 mg/m3, medium 5 mg/m3, and high 11 mg/m3.

Fixed Concentrations

At the medium and highest concentrations, the test lasted for 60 minutes. At the lowest concentration, the test lasted for 120 minutes to make sure enough dust was sampled by the gravimetric samplers to achieve a reliable reading.

Stepped Concentrations

Dust concentration was tested in three steps (20 minutes at each stage) from the lowest to the highest. Once at the maximum, the concentration was stepped back down to zero at the same rate.

Head to Head Headline Test Results

In a word… impressive

  1. The XD One performs as well as, or better than, all rival products in the accurate monitoring for respirable dust (PM 4.25) test at typical workplace concentrations of 5 mg/m3 and below. With official Workplace Exposure Limits allowing a maximum of 4 mg/m3 exposure at any time, it’s these concentrations that really matter in terms of real-world monitoring.
  2. The XD One’s performance was both consistent, repeatable and aligned with the best of the gravimetric sampling units (the current industry standard/methodology) at these dust levels.
  3. The XD One also performed as well or better than competitor products in the ‘stepped-tests’.

HSE Tests Prove The XD One is the Leading Wearable Dust Monitor on the Market

Saving lives and protecting workers’ health by preventing dust inhalation is a serious business. And so too is putting our technology and our reputation on the line against much bigger and better funded competitors, and vastly more expensive products. 

The HSE testing provided a clear endorsement of our ‘marker leader’ claim.  But it went further still. Taking into account the XD One’s size and weight, cost, ease of set up and ease of maintenance, the tests underlined its practical, performance and competitive advantages in the most emphatic terms. 

The results speak for themselves.

When faced with a rational decision between the XD One and a competing product – the  choice is crystal clear. You’d choose the XD One every time.
