A static dissipative, soft toe clog-style shoe features a long-wearing polyurethane body and toe construction to protect wearers against abrasions and chemical spills. The low-cut Safety Toe Shoe offers an athletic style with a steel toe cap. The water-resistant, leather upper has a wrap-and-stitch oil-resistant shell outsole.

For benchtop or equipment applications where space is limited, the EndStat portable ionizer provides a steady ionizing airflow for rapid electrostatic charge neutralization.
According to the manufacturer, the unit takes up eight square inches of work surface and reduces a 1000V charge to less than 100V in less than six seconds at a distance of 1 foot using steady state DC ionization. A swivel mounting bracket enables the product to be mounted overhead on the wall or attached to the workbench.
Liquid flow control
The Quantim device for low flow applications utilizes the Coriolis principle of direct mass measurement technology. According to the manufacturer, the unit delivers fluid accuracy of better than 0.5 percent, regardless of the fluid being measured. The product measures the direct or actual mass, rather than inferred, so no calibration is necessary. The device's through flow path eliminates clogging.
Mass flow meter
Full implementation of HART Protocol in the Innova-Mass multivariable vortex mass flow meters provides access to all measured variables and programming menus and permits field configuration without disruption of the existing measurement signal. The units provide outputs for five process variables: mass flow rate, volumetric flow rate, temperature, pressure and fluid density. Model 240 is available in both in-line flanged and wafer flow bodies, in sizes from 1 inch to 8 inches. Model 241 insertion-type meter is available with either flanged packing-gland or compression-fitting process connections.

Intended for use with production chemicals, pharmaceuticals, woodworking and welding smoke, Jet-Pulse dust collectors feature continuous operation with power cleaning and are available with 99.9 percent efficiency tubular filter bags or compact pleated filter cartridges. Filters for SPV and TL models can be changed without entering the unit, according to the manufacturer. The products are available with motor-driven rotary airlock for 24-hour dust disposal.
