 Turbidimeter PCE-TUM 20
Portable turbidimeter according to ISP 7027 /
Two automatic switching measuring ranges between 0 ... 50 NTU and 50 ... 1000 NTU

The turbidimeter is a handy device equipped with a large display, fulfilling all standards for a tubidity analysis on-site. The measuring range of 0 ... 1000 NTU is parted into two automatically switching measuring ranges for purposes of increasing the accuracy of the turbidimeter. With a well-arranged keyboard the turbidimeter is easy to operate. LED's are used as a light source, which work with a wave length of 830 nm in infrared ranges of light, und by that are invisible to the human eye. Since the measurement is not performed in a visible range, possible pigmentation of the sample plays a minor role during measurement. Due to a formation of the photodiodes in a 180 ° and 90 ° angle, transmitted light measurement is performed for higher ranges whereas diffused light measurement is used for lower ranges. With the reference standards of 0 NTU and 100 NTU included in delivery, the turbidimeter can be calibrated or adjusted at any time. The turbidimeter PCE-TUM 20 fulfills according to EN 27027 / ISO 7027 all acquired standards. If there are any questions about this turbidimeter PCE-TUM 20, please have a look at the technical specification below or call: UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703. Our technicians and engineers will gladly advise you in all photometers and all products in the field of measuring instruments, regulation and control and scales

Units

The turbidimeter PCE-TUM 20 displays the measurement results in NTU units (Nephelometric Turbidity Unit). This unit is preserved in the ISO standards. NTU is identical with FTU (Formazine Turbidity Unit). Furthermore there are two more units in practice for turbidity: JTU and SiO2. JTU (Jackson Turbidity Unit) is equal to 19 NTU, while the Silicia Unit equals 7.5 NTU. 

Measuring Principle

Inside the turbidimeter there is a infrared LED installed with 850 nm as a light source. A photodiode positioned in a 90 ° angle to the measuring ray absorbs the light reflected by the particles in the dissolution (diffused light or nephelometric measuring methods for lower measuring range). For higher measuring ranges an additional photodiode is positioned at the opposite side (measurement is performed via transmitted light method). By that the meter determines the turbidity in NTU (FTU). By using infrared LED even measurement of colored dissolution e.g. red wine is possible .
