XD ONE vs other dust monitors on the market

An independent UK agency responsible for the encouragement, regulation and enforcement of workplace health, safety and welfare, and for research into occupational risks in Great Britain, carried out a series of tests on three XD One Portable Dust Monitor units. 

They compared them to the following dust monitors: Casella CEL-712 Microdust Pro, a Thermo Scientific MIE Personal DataRam (pDR) 1500, a TSI SidePak AM510. 

The key elements of the testing were as follows: 

  • Tests were carried out in a calm air chamber. 
  • The tests used Arizona road dust, the industry standard for accuracy measurements and calibration. 
  • Fixed Concentration tests were performed at 2 mg/m³, 5 mg/m³ and 11 mg/m³. 
  • Stepped Concentration tests were performed moving from 2 mg/m³ to 5 mg/m³ and finally to 11 mg/m³. 
  • Simultaneous readings were taken using laboratory grade gravimetric sampling (TIOM and GK 2.69) to provide baseline accurate data from which to compare the portable units.

The results from the independent testing demonstrated that the XD ONE performs better than other personal dust monitors on the market. There were five critical messages from the testing as outlined below: 

  • The XD ONE performs as well as or better than the rival products in accurately monitoring for respirable dust. 
  • The tests found that the XD ONE unit’s performance was consistent between the XD ONE units, demonstrating that the good performance was consistent and repeatable. 
  • The XD ONE was consistent with laboratory grade gravimetric sampling units (the current industry standard, and often regulated methodology) at the tested dust levels. 
  • The XD ONE also performed as well or better than competitor products in ‘stepped-tests’ where the dust concentration was changed over time. 
  • The XD ONE is smaller, lighter, less fiddly and a single self-contained unit. 

XD ONE: The leading portable dust monitor on the market

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 Portable Dust Monitor 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 1 m x 1 m x 3 m calm air chamber, at three different dust concentrations – low 2 mg/m³, medium 5 mg/m3, and high 11 mg/m3.

Fixed concentration tests

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 concentration tests

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 (WEL) 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’.

Independent 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.
