Calibration, consultation services offered
To offer calibration, specialist training, consultation, product development and research services, Able Instruments and Controls is collaborating with Colorado Engineering Experiment Station.
Designed by experienced instrument engineers familiar with your applications, the MTO combines high technology with plug-and-play operation, very modest maintenance, freedom from calibration, and built-in capacity to rapidly measure up to four sample lines.
This laboratory technique has been re-engineered into a robust system suitable for general industrial use.
Drawing upon a first principle of physics, Beer's Law, Meeco's MTO systems use absorption spectroscopy to select and to quantify moisture concentration in sample gas.

Portable moisture and dew point sensors
ABLE Instruments and Controls has been appointed as distributor for Xentaur's range of fixed and portable moisture and dew point sensors and transmitters within the UK.
As the signal generated relates directly to the moisture concentration, there is no need for calibration.
Moreover, because the MTO measures the time of light decay within the optical cell, the device is impervious to atmospheric interference, unlike other laser-based techniques.
The principle of operation of the Meeco MTO is based on the simple concept of light signal decay between two highly reflective mirrors.
A corrosion-resistant flow system, robust design, flexible software and pioneering sensing technology, combine to make the MTO the most versatile moisture analyser available.
Seven years of intensive research and development have resulted in a product that is truly at the frontier of gas analysis for the 21st century.
Essentially the design provides a complete lab-in-a-box, to save time, money and space.
Ready to use on delivery, the MTO does not require special skills for start up or to access its many features.
Its menu-driven microprocessor control accesses a menu that allows ready access to all variables, including start-up and shutdown procedures online.
The MTO requires no calibration and because there are no moving parts, no consumables and measurement is completely noncontact, maintenance is virtually nonexistent.
The MTO fits into a standard 19in rack, while providing the capacity to monitor up to four sample lines simultaneously.
By virtue of its patented use of continuous wave (CW) lasers, the MTO has low power requirements with no sacrifice in laser lifetime.
No power-hungry pumps, heaters, or ionisation sources are required.
The low power consumption of the MTO-1000 means it is suitable for use with a UPS for continuous monitoring even during power cuts.
The gas manifold allows users to measure up to four sample streams, ideal for verifying purifier performance Because it relies on an absolute measurement, the MTO-1000 requires no cumbersome, time-consuming calibration procedures.
Indeed, the MTO has a built-in function to perform a zero check, free of purifiers and costly purified gas.
The MTO simply tunes the laser to a wavelength where no moisture absorption occurs, making the water "invisible".
In this mode, the system can characterise all other sources of signal to serve as a baseline.
The MTO then deducts the baseline from the measurements taken when the laser returns to its absorption point.
The zero check is initiated manually or programmed to occur at predetermined intervals, depending on need.
Portability Built to withstand mechanical shocks, MTO systems are ideal for portable applications.
In addition there is no requirement to restabilise, reset, recalibrate or in any way reconfigure the MTO when users go from point to point.
The unit continues to monitor in real time, without delay.
Built-in diagnostic tools facilitate easy online service and maintenance.
The MTO constantly monitors all operating and measurement parameters.
System events and faults are logged to the internal hard drive in the unit.
It is possible for Able to remotely interrogate any MTO system worldwide by using the built in Ethernet connection and the Internet.
In this way Able can provide expert advice and back-up quickly and easily.
