ILIUM Technology Introduces Ultra-low, Ultra-wide Range Conductivity Meter and Sample Independent Smart Probes


Model 2100 meter and probes cover twelve decades of range--from aqueous solutions in the milli-Siemen/cm range down to non-polar solvents as low as 1 femto-Siemen/cm.

Medford, MA/June 22, 2015 - ILIUM Technology announced today the availability of its Model 2100 ultra-low, ultra-wide range conductivity meter and sample independent smart probes. The Model 2100 and its associated line of high-accuracy smart probes is capable of measuring the conductivity of liquids from 10-3 S/cm, such as low concentration salt solutions in water, down to 10-15 S/cm, approaching hexane and other highly non-polar solvents.

Chemists, material scientists, process engineers, laboratory technicians, and laboratory managers will find the 2100 meter to be ideal for a wide range of applications including: chemicals, pharmaceuticals, biotechnology, personal care, food, paints, inks, petroleum, semiconductors, and electronic displays.

“The Model 2100’s ultra-wide range enables it to cover a sample scope that would previously have required several meters, providing both cost effectiveness and improved analyst productivity,” said Ilium’s Richard Melanson, director of business development. “And it makes it practical, for the first time, to track production processes and research experiments from an initial pure solvent through component addition and processing, or to use real-time conductivity measurements to monitor inline ‘clean-in-place’ processes for solvent-based systems, much as they are used today in aqueous cleaning processes. The instrument is small, robust, and easy to use on the bench top, in a fume hood, or on the factory floor.”

Key to the 2100’s performance are its range of smart probes, which are factory calibrated and completely sample independent. There is no need to recalibrate the probe every time a sample with a significantly different conductivity or dielectric constant is measured. This makes the Model 2100 and its probes unique in their ability to follow a titration or production mixing process as the target liquid’s conductivity moves through several decades of conductivity range. The NIST traceable factory calibration of ILIUM’s smart probes covers the full range of use for each probe. This ensures high accuracy over the full range of the probe and eliminates the need to field calibrate the probe over difficult to calibrate ranges.

The probes are extremely easy to clean and can be disassembled for cleaning and reassembled in seconds with no change in the cell constant, providing complete reproducibility. This is an important advantage when measuring emulsions or particle dispersions, such as paints and inks, which often leave particles or droplets deposited on the electrode surfaces. The ability to measure conductivities over such an ultra-low, ultra-wide range makes the Model 2100 ideal for the characterization of inks, paints, pharmaceutical and personal care formulations, resins, liquid toners, and other non-polar as well as polar fluid systems.

The Model 2100 Conductivity Meter and fully immersible 1020 Smart Dip Probe, covering the range from 2.5 μS/cm down to 25 fS/cm, are available now. The 1021 Smart Flow-through Probe, covering this same range, is planned for release this summer. The 1010 Smart Dip Probe will cover the range from 1 mS/cm to 5 pS/cm and is scheduled for release this fall. The probe covering the range from 0.5 µS/cm down to 1 fS/cm will complete the product suite, and is expected to be available in 2016.
