Tool measures environmental, air quality parameters

The new Multinorm universal instrument monitors indoor environmental and air quality parameters.

Available measurements include air temperature, air velocity, relative humidity, dewpoint, illuminance, luminance, CO, CO2, and sound (Class 1 and 2) analyses.

Additional features include luminance measurement, contrast, globe temperature, thermocouple (contact temperature), predictive mean vote, predictive percentage of dissatisfied, and wet bulb globe temperature.

It can operate in two modes. In the on-line mode, it displays current measurements; or, in the logger mode, it automatically stores all measurement values per logging interval.

Software is included for data analysis, charting, and reporting. Firmware is upgradable for future new probe additions.

New expansion joints for corrosive environments

New PTFE molded expansion joints are spool-type flexible couplings designed to compensate for movement and abate noise in severe corrosive environments such as chemical and petrochemical plants.

Engineered, designed, and built for use in extreme applications, expansion joints can be used where metallic joints/lap joints, or PTFE and FEP-lined types may have been previously specified or used.

Expansion joints are available in two, three, four, or five convolutions in a variety of dimensions and operating temperatures. Joints are delivered complete with ductile iron flanges and control units ready for immediate installation in the field. Flanges in other alloys are available by special order. Inquire for availability of other materials. Flanges are protected to resist atmosphere corrosion and are tapped to the ANSI standard drilling of 150 lb.

Control units are assembled with flanges to prevent joints from excessive axial elongation. The company sets the tie-rods at the factory at the maximum face-to-face working limits, with lock nuts protecting against overextension. Other expansion joints offered by this firm include traditional spool type, eccentric or concentric reducers, and offset designs, spherical arch, and nonmetallic ducting joints.
