MX6 iBrid Gas Detector

to see hazardous levels of oxygen, toxic and combustible gas, and volatile organic compounds (VOCs) like never before. The MX6 iBrid® is more than an intelligent hybrid of Industrial Scientific’s best monitoring technologies. It’s the first gas monitor to feature a full-color LCD display screen.

The display improves safety with clear readings in low light, bright light or anywhere in between. Whether the work is outside, inside or underground, it’s easy to see what gas hazards lurk in the immediate work environment. And a color display is more than eye-catching. It allows the user to step through instrument settings and functions with an intuitive menu and the instrument’s five-way navigation button. It even supports the option of on-board graphing for easily interpreted direct readings and recorded data.



Lux meter

Testo 545

Light intensity in workplaces must fulfil minimum values and have to be checked regularly. Using software, a site list can be stored and individual luminous intensity values can be connected to form a curve. This light profile provides information on the uniformity of the lighting.

The testo 545 lux meter for natural and artificial light comes with a permanently attached light sensor, which allows you to measure the light intensity in the workplace, and at offices, schools, and hospitals quickly and reliably. The optional software can be used to compile a light profile from the light intensity readings.

At-a-glance look at the benefits of the testo 545 light meter. The testo 545 lux meter can be used for selective and long term light intensity measurements. It has a built-in data logger which can save up to 3,000 readings, and can be used to perform  selective and time-based averaging. The optional testo turbo printer allows you to print out on site.
The optional PC software allows you to set up to 99 measuring sites, allocate the readings to the relevant measuring sites, and connect individually saved readings to form a curve. The light profile obtained from such data provides you with a picture of the uniformity of the lighting.





AirCube™ COM2 TH

The era of samplings with long interminable settings can be considered over with the new AirCube™ COM2 TH portablesampler. With just a few operations in the user-friendly preparation menu the sampler is immediately ready for a new sampling process.

The times of manual By-Pass or inaccurate and impractical calibrated orifices for high and low flows are over. You just need to set the desired flow and then let the sampling begin.

With the flow range included among 0.4 and 30 liters per minute in a single dynamic scale, the AirCube™ COM2 TH has no competitors! The first and only ultra compact The AirCube™ COM2 TH sampler is the true compact in the category with only 24 cm (per side) and 27 cm (height) but with inside the dry volumetric counter as required by the most common current norms.

Unique in its category, equipped with a membrane pump powered by 12V DC elevated flow range and back pressure compensation over 2200mm/H20.

The AirCube™ COM2 TH constant flow sampler belongs to the second generation of portable successful line of samplers manufactured by AMS Analitica.

New for its compactness, lighter in weight, has an exclusive proportional valve for a precise suction flow adjustment. The AirCube™ COM2 TH sampler is adjustable with operational flow included in a single dynamic range among 0,2 and 30 liters per minute without the assistance of by-pass valves and without using particular regulators for operation in the low-flow range. Unique in its category, the AirCube™ COM2 TH sampler is powered by rechargeable batteries and directly from the electrical power network without the use of external power packs. The new microprocessor board with high-resolution, back light graphic display allows an easy and intuitive data setting and immediate readings during operational sampling phases, real time readings all of the information reported to it such as:

  • Immediate flow and average flow of the session,
  • instantaneous dry gas meter temperature and average session temperature,
  • instantaneous environmental temperature and average session temperature,
  • instantaneous and average atmospheric barometric session pressure,
  • Partial volume sampled and sampling time. Furthermore, still from the display it is possible to follow the progress of the sampling graphically distributed on the base of aspiration flow and time. This option allows the verification and validation of the sampling validating the data with the calculation of the standard deviation.
