Sensorex Transmitter Provides Real-Time Data For Pool Monitoring
Sensorex’s TX-3000 pH/mV Transmitter monitors changes in pH or oxidation reduction potential (ORP, measured in mV), and temperature for more accurate disinfection control in commercial pools, spas and aquatic attractions. The TX-3000’s data can be used to regulate chemical injection pumps to ensure proper sanitiser levels.
The line-powered TX-3000 can be user programmed on-site to measure either pH or ORP (Redox), both important parameters determining the quality and safety of bather experience. Its dual output design, with an isolated (0)4 – 20mA output for pH or ORP readings and one for temperature measurement, eliminates the need for a separate temperature transmitter. A large backlit LCD screen displays both parameters simultaneously and two adjustable Hi/Lo relay contacts deliver results to automated injection control systems. With an extended pH measurement range of -2.00 to 16.00, the TX-3000 is suitable for a full range of applications. The NEMA 4x, IP65 enclosure can be wall, panel, or pipe-mounted for easy integration in most installations. The TX-3000 can be easily programmed onsite with its push button interface. The unit can be password protected for secure installations.

Hugo Lahme Takes The Next Step Toward More Brightness And Efficiency
Hugo Lahme GmbH, a leading manufacturer of high-quality swimming pool technology and equipment has announced the next generation of VitaLight® POWER LED under-water spotlights. This new series of ‘Made in Germany’ spotlights possesses numerous innovations and replaces the proven and sought-after first generation of the premium spotlight. This POWER LED 2.0 series simplifies cable installation as it is operated by intelligent DC Powerline Technology by way of 2-wire technology.
It also set new benchmarks in the sector’s light yield and brightness. Up to 50% more brightness at almost equal power consumption compared to the former monochrome VitaLight®
underwater
spotlights and still clearer, more brilliant colours in the RGB variations provide ever more impressive colour designs for swimming pools. Also design choice has increased with both the known and proven round stainless steel
covers as well as new, high quality rectangular covers made of stainless steel (316L/316Ti) being available for all POWER LED spotlights. All new VitaLight®
POWER
LED underwater spotlights are suitable for a wide range of pool types including the retrofitting of existing facilities. With the launch of the new underwater spotlights, the company will also simplify its product descriptions and in future, all new spotlights shall carry the specification VitaLight®
by the number of LEDs in the spotlight. The new large spotlight consequently carries the specification VitaLight® POWER LED 30 as it possesses a total of 30 POWER LEDs. The specifications of the former spotlights shall not change.

Don’t Believe Everything You Read These Days!
We all like the feel good factor that comes from buying British products, but is British design really any better than the plethora of cheap imports?
When it comes to heat pumps, British really does seem to be best according to Calorex. With the coldest and wettest April and May for 200 years, it seems many who installed imported heat pumps last year now regret that decision. Pool builders are fighting for excuses to explain the ice build-up and their failure to perform in the cold. By contrast, the rapid defrost facility and superior performance of Calorex has proved their ability to handle the extremes of the UK weather. Designed and built in Britain for the British climate, the Calorex X range uses a hot gas defrost to melt ice rapidly
28 February 2013 SPN
and ensure that pools are heated in air temperatures down to 3o
C. If you want to
go even lower, the Y range features superior reverse cycle defrost, drip tray defrost and crank case heaters as standard, ensuring efficient reliable operation 365 days a year in temperatures as low as -15o
C.
It’s sad to say, but not all manufacturers are as scrupulous about their claims as Calorex. The company tested four of the best- selling imported models, comparing their own claims with their actual performance and shortfall against claimed figures ranged from 28% to a whopping 44%! What is immediately obvious is that competitors are very free and easy with figures they produce but even the best do not compare with a Calorex, independently
verified by BSRIA. Quoting performances at 26oC is ludicrous when we seldom achieve that in the UK. Certikin’s heat pump sizing chart can be trusted, without the need to move to the next one or two model sizes up. According to Calorex, for April to October operation, based on electricity at 10.5p/kWh and gas at 3.9p/kWh, heating a typical 45 m2
outdoor pool using gas will cost £1,475/
year, using a Calorex £925/year, or £1,529 using the best of the imported models. In other words, the customer would be better off using a gas boiler than even the best of these inferior brands!
