The PolyCera Hydro (photo) is a new ultrafiltration membrane for drinking water applications where total suspended solids (TSS), turbidity and pathogen removal are of concern. PolyCera Hydro can be used in place of conventional polymeric membranes for drinking-water treatment in…
The sound waves from the discharge side of this company’s Delta Screw compressor can reach 170–190 dB. Therefore, a downstream silencer is obligatory, as with other compressors. In conventional dissipative silencers, the high frequencies of the sound waves lead to…
The HPP272 probe for the measurement of vaporized hydrogen peroxide (photo) can measure not only the hydrogen peroxide content (ppm) of bio-decontamination processes, but also temperature, relative humidity (RH, only water vapor) and relative saturation (RS, whole gas mixture). The…
The new digiVIT digital variable impedance transducer for linear position, displacement and proximity sensing (photo) features a self-tuning bridge that can work with nearly any sensor and any conductive target. The transducer also features simple pushbutton calibration, temperature compensation and…
The Ultima X5000 gas monitor (photo) is a replacement for this company’s Ultima X device, eliminating the need for specialized setup tools or a separate controller. The Ultima X5000 can be operated from the two touch buttons on its OLED…
