The Polaris C Optical meter is an almost maintenance free meter for measuring dissolved oxygen and temperature. The meter is sturdy, easy to use and has an extensive longevity making it ideal for harsh conditions.
Polaris C can store up to 2500 complete set of data, including time and date stamps. The logged data can be stored either manually or automatically with the possibility to group the data into categories. The stored data can be uploaded directly to Cobália using Bluetooth.
Scan the Cobália NFC tag on the tank and all data will be uploaded to your “digital farm”. Tank specific data assigned to the tags will be stored in Cobália for analysis on temporal variation, generation of graphs and for multivariable analysis on performance. The meter has a built-in self-check of all hardware, it compensates automatically for barometric pressure and it has a notably short response time. With this meter, you get the high-quality associated with OxyGuard technology and a product that will serve you well for many years.

Following successful field trials of a new micro bubble diffuser designed for the fish farming industry, Mantec has now launched an enhanced variant of the product into the market place under the brand CORALith. Building on our heritage of supplying more than 300,000 ceramic diffusers in the past 20 years, this new micro bubble diffuser introduces very small bubbles into the body of water, resulting in more surface area per unit volume and greater oxygen transfer exchange. In addition, agglomeration of bubbles as they rise to the surface is minimised.
Mantec has been active in the supply of ceramic diffusers into the aquaculture sector since the 1990s. In recent times, the sector is increasingly demanding diffusers which produce the finest bubbles to ensure adequate and efficient oxygenation of the water in which fish are farmed. The need for finer bubbles is grounded on maximising the oxygen transfer at greater water depths.With this in mind Sterner's new Mantec diffuser is based on a porous ceramic tube, having a closely controlled pore size of one micron. This results in even, fine bubbles to produce efficient oxygen transfer. Fitted with two square stainless steel end caps, the CORALith diffuser assembly can be positioned in the tank in any horizontal orientation, without the operator having to be concerned that the diffuser is sitting flat on the base of the tank. The diffuser assembly is designed with a replaceable ceramic tube.Furthermore, the diffuser has been designed to minimise any potential leak paths, thereby ensuring the efficiency of oxygen transfer. Thanks to its robust construction, the operator need not be concerned about removing the diffuser from the tank when the oxygen feed remains switched on. In addition, the hose tail coupling does not rely on push-fit connections, instead it is secured with a British Standard Pipe thread to provide a secure connection with the mating hose.
WEDGE-LOCK™ uses an ultra fine pore ceramic producing a high Absorption Efficiency (AE) allowing you to increase yield while controlling the cost of expensive gases
The Point Four WEDGE-LOCK is a modular system of microbubble diffusers and end sets that fit together to form a bank of up to eight units. Oxygenation capacity can be increased (or decreased) as your needs demand by simply changing the number of diffusers used for greater flexibility and minimal downtime.Designed for total ease of use, WEDGE-LOCK™ modules ‘Twist and Lock’ together to form an air-tight seal without the use of tools. Hose with push-in fittings connects the diffuser banks to the gas supply, significantly reducing set-up time and effort.Manufactured from tough plastic, WEDGE-LOCK™ will not corrode and is resistant to the Sun’s ultraviolet rays. The diffuser’s streamlined wedge shape improves stability in tanks with high water flow and offers less resistance in self-cleaning tank systems.

Description
The OxyGuard Handy MaxiTemp 2 temperature meter, is a small electronic thermometer specially designed to meet the demands of fish farmers and other professional people for a rugged, reliable and accurate thermometer with data logging function. It has a measuring range of -5 to +45°C with an accuracy of +/- 0.1°, and will measure up to +60°C with an accuracy of +/- 0.2°C. The probe is manufactured in plastic and sea-water resistant stainless steel, and is connected to the display with a 1.5 m cable. Both probe and display are sealed and waterproof. Values can be stored either automatically at preset time intervals, or manually. You can group values according to the place of measurement. Stored values can be transferred to a PC using the Polaris Link, which connects to the PC via a USB cable. The MaxiTemp is 96mm in diameter by 36mm. For a meter to read oxygen and temperature please have a look at the OxyGuard Handy Polaris C.

Many applications benefit from using the high efficiency, large surface area, low pressure drop and inert properties of the WRAS approved Premier Pleat Polypropylene cartridge. Four pleated media layers combine to construct a pleat pack with depth characteristics and the main filtration media layer delivers high efficiency and exacting micron classification. An improved cage construction for 2018 delivers excellent flow dynamics and is designed to protect the integral pleat pack whilst providing overall rigidity and strength to the cartridge.
Flexseal AC2654 adaptor coupling with a shear banded seal, designed for pipe with an outside diameter of 240mm to 265mm and 144mm to 160mm. Manufactured from EPDM rubber, incorporating a Grade 1 304 stainless steel shear band.
Fernco shear banded couplings are specifically designed to connect and repair pipes on adopted sewer and drainage applications, as required by the UK water companies. The stainless steel central band protects the joint under shear loads and helps to keep the joining pipes aligned, helping to prevent pipe displacement.
Fernco shear banded couplings are specifically designed to connect and repair pipes on adopted sewer and drainage applications.
Shear banded couplings are a requirement of the UK water companies when connecting onto their assets. This requirement forms part of Water Industry Specification (WIS) 4-41-01, which outlines the requirements to connect pipes on adopted systems using only shear banded couplings.
The shear band on this range of couplings gives the connection added protection against shear loads that could cause the pipes to become mis-aligned.
Features & Benefits

Stainless steel shear band helps prevent pipe displacement
Less excavation compared to replacing a whole length of pipe
Approved to WIS 4-41-01- Flexible couplings for gravity sewerage and drainage pipes
Approved to BS EN 681-1:1996, BS EN 295-4:2013 & BS EN 10088-2:1995
Flexseal provides the most extensive range of Standard Couplings available in the marketplace and has revolutionised traditional pipe repair methods over the years. Flexseal Standard Couplings are specifically designed to connect and repair pipes of different materials or sizes used in sewerage, drainage and other underground applications. When excavation work is required to repair a damaged pipe, Flexseal Standard Couplings will reduce the amount of time required and minor differences in pipe diameter can be accommodated. The combination of a durable design and excellent sealing properties when tightened to the correct torque enable the Flexseal Standard Coupling to provide a reliable seal on rough pipe surfaces e.g. concrete, as well as on smooth surfaces e.g. PVC. Standard Couplings can be combined with Flexseal Bushes in order to act as an adaptor between pipelines of differingoutside diameters. Flexseal can also supply the product with nitrile sleeves for use with effluent which may be contaminated with hydrocarbons. Couplings are also available with Grade 1.4401 (316) stainless steel for improved corrosion protection.
