Turbidity meter is easy to use
Portable meter sealed to IP67 covers the range 0.01 to 1000 nephelometric turbidity units, making it suitable for a wide range of applications from drinking water to waste waters
Water analysis specialist Palintest has introduced a new multi-range meter for on-the-spot measurement of turbidity in water The Micro 950 waterproof turbidimeter is a portable meter sealed to IP67, covering the range 0.01 to 1000NTU (nephelometric turbidity units), making the instrument suitable for a wide range of applications, from drinking water to waste waters

Turbidity is an important measurement for clean water systems such as natural and drinking water.
The test is also widely used in other systems such as effluent and industrial waters.
The new meter is designed for bench use in laboratories and for field use by sampling engineers or contractors.
It will accurately measure turbidity rapidly, in accordance with recent UK, EU and ISO standards, and requires no technical knowledge.
Turbidity is measured within the ranges 0.01-19.99NTU, 20.0-99.9NTU, and 100-1000NTU.
After a water sample is inserted in the meter a single button press displays the reading on a large LCD screen together with units, and status codes.
Accuracy is +/-2% of reading below 500NTU and +/-3% above 500NTU.
The turbidity is measured using the nephelometric principle.
A beam of light with a wavelength of 850nm is passed into the water sample and the amount scattered by the particles present is detected at right angles to the incident beam.
The use of a near infrared LED light source ensures precision, eliminating any interference from inherent colour in the water, and is in accordance with national and international standards on the determination of turbidity.
Powered by four AAA batteries, which should last for over 1200 test samples, the meter has automatic switch-off.
It is supplied as a complete test kit in a rigid carrying case including sample vials with light shield caps, and four calibration standards which can be used to confirm settings.
