This dead weight pressure gauge calibrator made of a precision machined piston & cylinder assembly mounted on levelling screws.
The gauge is thus subject to known pressures, which may be compared with the gauge readings and an error curve drawn.
A Bourdon gauge is supplied for calibration. The weights supplied are added to the upper end of the piston rod, which is rotated to minimise friction effects.
Representation of a typical clutch used in buses, composed of a traditional mechanical dry clutch coupled to a hydraulic joint allowing soft starting.

Provides light-weight inherent barrier protection against hazardous dry particles and aerosols, and nonhazardous light liquid splash.
Excellent abrasion resistance due its unique, nonwoven material
Lab coats with mandarin collars provide the protection and durability you need so you can focus on the task at hand.
Can be used in a variety of applications including general maintenance/operations, asbestos and lead abatement, mold remediation, and environmental cleanups.
The Flow Over Weirs is a kit containing two types of sharp crested weirs and a level gauge. The weirs have opening or sections at the top that allow flow; the Thomson weir with V-profile opening, the weir with rectangular profile opening. A sharp crested weir constricts an open channel flow, and helps in measuring flow rate using level gauge contained within the set.
The Flow over Weirs consists of five basic elements used in conjunction with the flow channel in the moulded bench top of the hydraulics bench.
A Vernier hook and point gauge is mounted on an instrument carrier, which is located on the side channels of the moulded top. The carrier may be moved along the channels to the required measurement position.
A quick release connector in the base of the channel is unscrewed and a delivery nozzle screwed in its place.
A stilling baffle locates into slots in the walls of the channel. The inlet nozzle and stilling baffle in combination promote smooth flow conditions in the channel.
The rectangular notch weir or Vee notch weir to be tested is clamped to the weir carrier in the channel by thumb nuts. The weir plates incorporate captive studs to aid assembly.

HV garments are mainly composed of flash spun polyethylene, providing an ideal balance of protection, durability and comfort. Thanks to their nonwoven structure, they are permeable to both air and water vapor, yet repel water-based liquids and aerosols.
HV garments are mainly composed of flash spun polyethylene, providing an ideal balance of protection, durability and comfort.
Thanks to their nonwoven structure, they are permeable to both air and water vapor, yet repel water-based liquids and aerosols. They offer an excellent barrier against fine particles and fibers, are ultra-low linting and antistatically treated on the inside.
Collared coverall available in fluorescent orange with silver grey retroreflective bands for day and night visibility, available in sizes SM to 3X.
Robust yet lightweight.
Their bright fluorescent orange color background material combined with silver grey retroreflective material make them highly visible during the day as well as in the night (when exposed to a light source).
Mandarin collar, elasticated wrists and ankles as well as glued-in waist elastic.
Ample crotch area for freedom of movement.
Large, easy-to grasp zipper puller.
Stitched external seams.
Auto-lock zipper and zipper flap for increased protection.
Very low inward leakage thanks to optimized design.
