Breath Testing with DataMaster™

Since the introduction of the original DataMaster in 1986 over 2500 have been sold worldwide. The DataMaster has a proven history of reliability, accuracy and repeatability. All DataMaster models use the proven method of Absorption of Infrared Energy to determine ethanol levels.

Currently three different models of the DataMaster are being manufactured: the BAC DataMaster, the DataMaster cdm and the recently introduced DataMaster DMT. Our in-house database management and communication software package (DM Host) is available for use with any of these instruments.

Some of the features that make the DataMaster family the best instrument available on the market today is:

The thermo-electrically cooled PbSe detector operates at 0șC. It is a well-established fact that the cooler the operating temperature of a detector, the more sensitive it becomes, allowing the detection of much smaller signals. By regulating this operating temperature the detector output becomes more stable, enhancing the repeatability, precision and low-level performance of the DataMaster.

A folded optical path gives the DataMaster the ability to perform accurately and consistently at levels as low as .001 BrAC. The infrared energy must travel this full length through the breath sample before focusing onto the detector. This distance permits maximum energy absorption, enabling the DataMaster to achieve accuracy of ±.002 at a .100 BrAC.

A small sample cell ensuring the validity of the breath sample across a wide range of subject vital capacities (lung) and blowing patterns.

The narrow bandwidth optical filters allow the passage of a very limited frequency range of infrared energy, permitting the DataMaster to be highly specific for not only ethanol, but to the virtual exclusion of other alcohols and potentially interfering compounds. The specificity of the DataMaster system is comparable to or exceeds that of other systems using multiple optical filters or other technologies.

The Grey Body infrared energy source produces primarily infrared energy with very little unusable visible light. This maximizes the power usage, enabling the DataMaster system to operate cooler, with greater stability and more efficiency than with any other type of energy source.
