Did you know?

The LTH of LTH Electronics is the initials of the three founding directors of the company: Le Gros, Tedder and Hall.

The first product sold by LTH Electronics was a LLC-A1 liquid level controller which was sold to ICI on the 21st of November 1967. The product serial number was 1002 and the LLC-A1 series of level controllers ran from 1967 to 2003. We would be interested in hearing from any customers who have any of our early products still in operation to find out who has the oldest LTH instrument still working.

Since their launch in 1999, LTH Electronics have manufactured and sold over 8,150 ECS40 series Electrodeless conductivity sensors for use in industrial process applications.

Our Sales and service team has over 98 years of experience and knowledge of instrumentation and sensors used in the process measurement world.

Did you know that over 1.2 billion 8 oz. servings of Coke are consumed daily around the world. LTH’s pH instrumentation is installed at a number of Coca Cola sites and is used to monitor the factory effluent to ensure they remain within their discharge consent levels.

Orange juice is acidic due to its content of Citric acid and typically has a pH of around 3.5 whereas Milk of magnesia is alkaline and typically has a pH of 10. As many factories have a discharge consent level of between 5.5 to 9.5 pH even some everyday liquids would need to be treated before they could be discharged.

The LTH product range has evolved since the company started in 1967 but conductivity measurement has remained a core product for LTH since the first conductivity instrument supplied in January 1968. Conductivity measurement still accounts for over 42 % of our turnover. We like to think of ourselves as conductivity experts.

In our last financial year we have exported products to over 40 different countries around the world. Exports now account for over 40 % of our turnover with 60 % of the exports going to countries outside the European Union.

As the population of Earth grows exponentially, it is increasingly important for every person on the planet to be aware of how much water he or she consumes and wastes. For example, if every human on Earth saved just one drop of water each day, the annual savings would be over 24 million gallons or 90,849,882 litres! One use for our conductivity systems is for rinse water control in process industries ensuring water consumption is controlled, reducing waste and costs and saving a valuable resource!

The monitoring and control of cooling tower water is vital to stop bacteria thriving and to prevent Legionella. The name Legionella goes back to an outbreak of severe pneumonia at a meeting of the American Legion in Philadelphia in 1976 where 221 people received medical treatment and 34 deaths occurred. Legionella can contaminate water systems such as cooling towers, central air conditioning systems, hot water systems, showers and spas. If you do not look after your water system you could have a problem! One of the successes of the MXD53 series is the MTD53 series cooling tower monitor which offers all the functions for dosing and control of cooling water. The MTD53 offers conductivity or timed bleed control, Biocide and Inhibitor control to help prevent the buildup of bacteria and Legionella.

High consumption of good-quality water is part of beer brewing. More than 90% of beer is water and an efficient brewery will typically use between 4 and 6 litres of water to produce one litre of beer. Water in breweries has many different uses including production-mashing, boiling, sparging, filtration, and packaging-breweries also use water for heating and cooling as well as cleaning and sanitation of equipment and process areas. Our Electrodeless conductivity instrumentation and sensors are widely used to improve processes and reduce water consumption in cleaning and sanitization processes.

Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.

The first documented primary flowmeter element was a crude form of weir used in ancient Egypt over 3000 years ago.

Despite the fact that total suspended solids or TSS affect Turbidity, Turbidity is not the same as TSS. They are, however, related. TSS is a measurement of the dry weight mass of non-dissolved solids which are suspended in the water. They are measured as the solids suspended per unit volume of water and expressed as mg/l. Both organic (like algae, zooplankton and detritus) and inorganic (like clay, silt and sand) solids are included in TSS. Turbidity refers to the optical properties of water and is not a measurement of the concentration of suspended sediments. Turbidity is not only affected by TSS, but also by the shape of particles, size distribution, refractive index, colour and absorption spectra. For a specific location and specific sediment properties, simultaneously measuring Turbidity and taking water samples for TSS analysis will normally result in a good correlation between TSS and Turbidity.

The UK water industry collects, treats and supplies more than 16 billion litres of water a day to domestic and commercial consumers and then collects and treats more than 10 billion litres of the resulting wastewaters, returning them safely to the environment

In a 100-year period, a water molecule spends 98 years in the ocean, 20 months as ice, about 2 weeks in lakes and rivers, and less than a week in the atmosphere.

Around 5 billion litres of milk are sold in Britain each year and we consume an average of 1.6 litres each a week. On top of that, 6 billion litres go into dairy products such as cheese, butter and dried milk powder, which is a vital component of many other food products. All in all, we buy enough dairy products every year to fill nearly 4,500 Olympic-size swimming pools. Our Suspended solids instrumentation and sensors are used in dairies for product standardization and product loss detection.

Pure water is actually a good insulator (poor conductor), meaning that it does not conduct electricity well. Because water is such a good solvent, however, it often has some solute dissolved in it, most frequently salt. If water has such impurities, then it can conduct electricity much better, because impurities such as salt comprise free ions in aqueous solution by which an electric current can flow.

LTH has been an ISO registered company since the 21st of November 1991 with product quality and customer satisfaction and important part of our success.

LTH now offers a complete range of level measurement transmitters including Pulse and Guided wave Radar, Ultrasonic, Capacitance, Conductivity and hydrostatic to meet process requirements.
