Measurement and Testing Portable analysers and detectors for moisture, BTEX and formaldehyde analysis
Chromatotec has recently integrated portable analysers for VOCs including BTEX and formaldehyde monitoring. These portable instruments offer rapid and accurate measurements with a detection limit lower than 1 ppb.
microVOC is a compact VOC analyser which allows continuous and real-time qualifi cation and quantifi cation of benzene, toluene, ethylbenzene, xylene. acrolein, phenol and 1.3 butadiene. microF is dedicated to formaldehyde analysis. This range of portable instruments also includes an automatic multi-tubes air sampler (4 channels) allowing to program sampling sequences with fast implementation in every environment.
Recently, Chromatotec has further expanded its range with a new trace moisture probe to provide complete solutions for measurement of humidity in chlorine (CL2), in pure gases including gases with more than 30% oxygen (O2) or hydrogen (H2), as well as in medical air and gases.

Myron L®
Company’s Ultrameter II™ Delivers Fast, Lab-Accurate Readings in a Handheld Instrument
Ultrameter II instruments provide a comprehensive suite of in-situ water quality analysis tools that can replace more costly and less convenient laboratory equipment.
A true, one-handed instrument, model 4P delivers Conductivity, Resistivity, TDS, and Temperature readings quickly and easily with autoranging capabilities that provide increased reading resolution across a broad range of applications. Unlike other similar meters, the 4P features the ability to select from one of three preprogrammed solution models, KCl, NaCl, or Myron L’s own 442 Natural Water™ Standard. You can also program a User solution mode based on a known solution yourself. The result is benchtop accuracy of ±1% of reading in a handheld instrument. Calibration is simple to perform using up and down arrow keys and a digital interface. And the 4P is IP67 dust-tight and waterproof, NEMA 6 submersible, and buoyant. Wireless data transfer is possible with bluDock™ option.
Model 6PFCE includes all features of the 4P but adds the ability to measure pH, ORP, and Free Chlorine Equivalent (FCE ™). pH readings are temperature compensated; you can choose to perform a 1-, 2-, or
Servomex has unveiled its Gas Guide for 2022, which is available to download from their website, the 2022 Gas Guide brings together all the information required to enable customers to fi nd the right gas solution for their process. The guide provides introductions to all Servomex gas analysers, service and system products for 2022.
Updating from the successful fi rst edition launched last year, the guide offers an expanded section of the solutions for key industrial applications, including new process diagrams and links to the latest videos.
Providing information on the gases measured, key applications, product features and benefi ts, there is also an improved A-Z directory of sensing technologies, with clearer and visual explanations as to how they work, and a section explaining the gas analysis solutions for a range of key applications.
The 128-page document allows customers to assess the key criteria when selecting the gas analyser, including gas measurement ranges, process environments, and the hazardous area, safety and environmental certifi cations offered.
Andy Cowan, President of Servomex, said: “Our 2022 Gas Guide provides everything our customers will need when it comes to fi nding the right solution for their gas analysis requirements.
“We’ve highlighted some key industry applications in this publication, explaining the processes involved and where our gas analyzers and systems deliver the most effective results.
“In addition, we detail the sensing technology that powers our innovative gas analysis – how it works, which gases it detects and what makes it the best fi t for certain applications.”

3-point calibration depending on the range of samples measured to achieve ±.01 pH accuracy. The pH sensor is of a proprietary construction and includes a large potassium chloride solution reservoir for long life. Myron L pH sensors are also user replaceable. ORP measurements utilize a 99.9% pure platinum electrode and a reference junction that is shared with the pH sensor. ORP accuracy achieved is ±1 millivolt. In addition, the 6PFCE
function is the fast accurate way to determine the killing power of free chlorine species in water. It employs
a proprietary predictive ORP algorithm to determine free available chlorine levels at the actual pH of water, so you know your chlorine treatment is effective.
