So you need multiple channels, battery power, outstanding accuracy, and the ability to read many different sensor types—but you don't need all the power of a 1 ppm Super-Thermometer. We have the answer for you.
Hart's 1529 Chub-E4 Thermometer gives you four channels, three major sensor types, lab-quality accuracy, and a ton of great features, all at a price you'll love. (read more)
KIN-TEK's new FlexStream™ automated gas standards generating instrument offers flexibility for creating precision gas mixtures. Mixtures are produced by diluting the emission from permeation tubes, or diffusion tubes, with an inert diluent, typically nitrogen or zero air. The FlexStream™ is ideally suited for creating trace concentration - ppm, ppb, and pptr - mixtures. (read more)
16th September 2008 - XP Power announces the launch of its MCM60 series of rugged, metal-cased convection cooled power supplies that are ideal for deployment in harsh and physically demanding environments. In addition, the series offers EMI performance to MIL-STD 461E/F standards, conducted and radiated, for emissions and susceptibility. Sealed against dust and water, the unit's metal case...
