The PRO range builds on the success of the Aquaprobe and Aquasonde series, elevating every aspect of the construction, design, features and specifi cations. They bring with them new- to-industry materials allowing measurement at far greater depths, a unique measurement chamber for improved sensor stability in the most demanding applications and smart sensors that hold their calibration data, allowing for simple sensor exchange in the fi eld.


Aquaread Launch new PRO range of multiparameter water monitoring instruments The PRO range come complete with all the key water


Both the Aquaprobe (AP) and Aquasonde (AS) models of the PRO range feature a combination of titanium and carbon fi bre, offering both exceptional corrosion resistance and high compressive strength. As a result, both are capable of measuring at extreme depths of up to 1000ft (300m).


The protective end cap, found on all Aquaprobes, has been extended along the inside of the sleeve. When screwed onto the sleeve it creates a more stable measurement chamber for all installed sensors. Its matt black design prevents refl ection and the sealed environment is not subject to interference from stray light.


The measurement chamber can also be used for sensor calibration using the calibration cup that push-fi ts to the base of the probe. This surrounds and seals the holes and allows the probe to stand upright. Utilising the measurement chamber for calibration in this way reduces the volume of calibration solution required, reducing maintenance costs.


The range sees the introduction of smart sensors, sensors that hold calibration data allowing exchange without the need to recalibrate. Sensors can be carefully calibrated in the lab and taken to the deployment site for simple exchange, removing the need to calibrate in the fi eld.


quality smart sensors as standard and is equipped with a self-cleaning system to keep them clean for prolonged monitoring. Standard sensors include optical dissolved oxygen, conductivity, pH, ORP, temperature and depth.


Four Auxiliary ports allow extra smart sensors to be installed, diversifying monitoring options.


The AS-PRO is fi tted with a novel three-position switch ring mechanism allowing you to confi dently switch the function of the sonde. Using the switch ring you can turn the unit off, set it to auto or activate Bluetooth mode. The switch ring includes multi-coloured LED for various indications.


When in Auto mode the sonde will detect if its connector has been blanked off, if it’s connected to a vented cable, if it’s connected to an Aquameter or if it’s connected to a PC via USB, and reacts accordingly.


When set to Bluetooth mode, using the SondeLink App, the user can take live data readings, calibrate the Sonde, set-up the logging regime, check battery and memory levels and upload logged data from the Sonde to the PC.


“The new PRO range expands our capabilities and opens-up new markets for us, it is already proving incredibly popular with our distributors and with our customers. We are very excited to bring this new product to the water monitoring industry this year.” Says Aquaread’s managing director Craig Harrison.

New mass fl ow controller great performance, low price and attractive delivery time


The ideal solution for precise hydrostatic pressure measurements in harsh conditions


email:


KELLER’s 26X level probe provides highly accurate and reliable hydrostatic pressure measurements with exceptional long-term stability, making it the ultimate solution for demanding environments.


For More Info, email: email:


The KELLER 26X level probe is designed with mathematical modelling to compensate for temperature dependencies and non-linearity by the microcontroller, to ensure highly accurate measurement results. The probe offers a scalable analogue output and a combination of analogue and digital interfaces, enabling straightforward integration into automation systems while facilitating the reading of measurements.


The 26X level probe boasts a robust, fully welded stainless-steel construction with high- quality cable glands, ensuring maintenance-free operation for years to come. The extended lightning protection option provides additional safety, making it the perfect solution for demanding environments.


The new SFC6000 is Sensirion’s next-generation mass fl ow controller, impressing with an unbeatable price–performance ratio and a very attractive delivery time of eight weeks. While the industry is currently struggling with delivery times of 30 to 53 weeks, SFC6000 samples are available within two to four weeks. In addition, selected SFC6000 confi gurations (labeled SFC6000D) are available by catalogue, meaning you can order them for initial testing and evaluation today and have the product in your mailbox tomorrow.


The SFC6000 is very compact and lightweight; it therefore allows the customer to optimise their devices in terms of size and weight. This is a decisive advantage, especially for portable devices. Furthermore, it offers great performance in terms of repeatability, accuracy, control range and speed. The SFC6000 is highly integrated and has a very robust supply chain due to how few electronic components are used. It is best suited for analytical instruments (gas chromatography or bioreactors), semiconductor applications and process automation.


Based on the principle of thermal mass measurement and using the proven CMOSens® MEMS technology, Sensirion builds revolutionary mass fl ow controllers with best-in-class performance and speed which – unlike most other devices on the market – do not drift and do not require in-service re-calibration.


If you are looking for a mass fl ow meter, the SFM6000 is a valve-less sister variant of the SFC6000 that offers the same performance at an even lower price.

email: High-effi ciency peristaltic pump with improved ease of use


For More Info, email: email:


Verder Liquids introduces the new Verderfl ex Dura 80 peristaltic pump. The Verderfl ex Dura 80 is a high-performance industrial peristaltic pump designed for a wide range of applications in the process industry.


The Dura 80 has a fl ow rate of 42 m³/h and a maximum differential pressure of 16 bar, making it an ideal solution for high-fl ow applications. New features include a lifting point, a lubricant fi lling point, and a new access cover for cleaning. These new features are based on feedback from users and are designed to provide easier operation and maintenance.


“We are pleased to announce the Verderfl ex Dura 80 as the latest addition to our Dura range,” says Michael Homer, managing director at Verder Ltd. “This pump sets new standards in performance and ease of use, providing an ideal solution for applications where high fl ow and discharge pressure are required.”


The key features which make a difference are the lifting point, for supporting the front cover if it needs removal, the lubricant fi lling point, to allow easy access for this task without requiring


removal of other bolting and the access cover at the bottom of the front panel to allow cleaning of any debris during hose change to ensure that the new hose has the best life.
