Inline turbidimeter
13 November, 2006Sigrist's AquaScat WTM turbidimeter offers maintenance-free inline turbidity measurement. The WTM model features contactless measurement, using a 'free-falling' stream together with programmable, automatic calibration. The AquaScat WTM has a wide measuring range from 0 to 4000 FNU covering all applications - from highly turbid raw river water, to optimally filtered pure water with 0.015 FNU. For normal measurement there is no need for a de-aeration tank, as the WTM model has an electronic, built-in bubble trap. This feature is sufficient for occasional bubbles. With an integral display and operating panel the AquaScat is fast and easy to install.
In situ oxygen and pH monitoring
11 September, 2006Ocean Optics offers unique sensors that can be used to monitor oxygen or pH in biological samples, headspace gasses, slurries, cosmetics, foods, gasses and liquids in natural environments. The picture shows a FOXY fibre optic oxygen probe monitoring headspace gas in food packaging.
Turbidity measurement
05 May, 2006With the introduction of the Turbimax CUE21-CUE26 compact line, Endress+Hauser now offers an alternative for turbidity measurement in drinking water and service (grey) water applications, while conforming to ISO and EPA standards.
Moisture analyser
18 July, 2005The Process Sensors MCT300 near infrared moisture analyser has a wide variety of industrial process applications giving simultaneous instant information on product constituents.
Graphic display pH meters
20 June, 2005Hanna Instruments has introduced HI4211 (single channel) and HI4212 (dual channel) meters with Calibration Check.
Electrochemistry meters
20 June, 2005Thermo Electron Corporation has unveiled the Orion Star series, a range of meters, accessories and solutions for electrochemistry measurement.
pH meters with calibration check
20 September, 2004The HI221 and HI223 pH meters compare the characteristics of the pH electrode from one calibration to the next. The Calibration Check feature alerts the user if parameters are not suitable for an accurate calibration.
Isoelectric focusing system
14 July, 2004The Ettan IPGphor II first-dimension isoelectric focusing system delivers high throughput, speed, reproducibility, and high protein-loading capacity.
Portable turbidity meter
14 July, 2004Hanna microprocessor-based portable turbidity meters provide laboratory-grade accuracy for field or laboratory use. HI93703-11 measures turbidity from 0 to 1000 FTU (NTU). For best accuracy, HI93703-11 measures from 0.00 to 50.00 FTU in steps of 1/100th of FTU. The meter meets ISO 7027 requirements. HI93703-11 is equipped with an infrared LED light source. The infrared LED has a long life and maintains constant emission for the life of the instrument. The wavelength peaks at 890 nm, which provides the required intensity of diffused light even in samples with low turbidity values, and also reduces the interference from colours.
Analytical determination of ions in water
08 November, 2001Water analyses are carried out by many different laboratories for a whole variety of constituents for as many different reasons. Techniques that involve the direct determination of ions present in the water play key roles in these analyses
pH electrodes evolve into the silicon age
08 March, 2001Silicon chip pH sensors overcome breakage, maintenance and storage problems. Since the early 1930s when the first pH meter was invented, the core technology for quantitative pH measurement has, until recently, remained fundamentally unchanged
