Turbidity Standards are stabilized standards prepared in ready-to-use concentrations to ensure accurate turbidity measurements.
Save time and eliminate errors - no need for dilution
EPA approved primary turbidity standard
Eliminate the opportunity for inaccurate turbidimeter calibrations resulting from the improper dilution or handling of stock solution.
Long shelf life
As a primary standard, Turbidity Standards can be used to calibrate or verify any manufacturer's turbidimeter.
All concentrations of Turbidity Standards are verified to meet tight quality control specifications, are EPA and ISO compliant for reporting purposes and guaranteed to save you time.

Vibration analysis is a key tool in estimating the condition of a roller bearing. The spectral distribution can deliver accurate information on the type and location of the damage. This accessory set-up contains six roller bearings on which different faults can be detected and explained. The slow change in the vibration spectrum provides indications of the remaining life of a bearing and can be used as a criterion for its replacement. The radial load on the bearing can be set within broad limits using the belt drive accessory set (setting of belt tension; fixed load).

Self sealing quick release connections enable rapid connection to and conversion from parallel to counter current flow. An extended version with 3 pairs of intermediate points and a total of 10 thermocouples is also available.
A clear acrylic tube containing cold water surrounds an inner stainless steel tube in which the hot water flows. Six thermocouples measure hot and cold inlet, mid-point and exit temperatures. Total heat transfer area of approximately 24000mm2.
The Electro Fluid Power Learning System provides learners with the components to set up a variety of industrial relay control circuits using ladder diagrams and Boolean logic. Electro Fluid Power Learning System can be used with eight different basic pneumatic or hydraulic learning systems to teach electrical relay control of hydraulic and pneumatic systems and their industry applications. Some of these components include selector, pushbutton, limit, and pressure switches; control and timer relays and hydraulic and pneumatic directional control valves. Learners will practice industry-relevant skills related to these new topics including developing a sequence of operations given an application, connecting and operating an indicator lamp given a ladder diagram, and many more. In addition to strong curriculum and industry-standard parts, the Electro Fluid Power Learning System includes an instructors guide, install guide, student reference guide, and the option to purchase an interactive multimedia format of the curriculum. The learning systems that can be used with the Electro Fluid Power Learning System include Basic Hydraulics, Basic Pneumatics, Double-Sided Hydraulics, Double-Sided Pneumatics, Basic Fluid Power, or Double-Sided Basic Fluid Power.

The range consists of a series of different cutaway models of drive system components. The mechanical functionality of all components is retained in full. Each of the cutaway models is securely mounted on a base plate to which handles are attached for carrying purposes. All components are industrially relevant and have been prepared such that individual active elements are clearly visible to the user. All mechanisms are hand-driven.

The components are clearly but compactly arranged in a manner similar to that used for many domestic air-water heat pumps and all are visible from the front of the unit.
The Water Water Heat Pump consists of a hermetic compressor, an efficient plate heat exchanger condenser and evaporator, a liquid receiver, a thermostatically controlled expansion valve.
The operating cycle is as follows:
Slightly superheated Refrigerant vapour enters the compressor from the evaporator and Water Water Heat Pump pressure is increased. Heat is given up to the cooling water and the refrigerant condenses to a liquid before passing to the liquid receiver and then the expansion valve. This brings about a rise in temperature and the hot vapour enters the water cooled plate condenser.
