WTW portable turbidity meter Turb® 355 T
The WTW Turb® 355 T portable turbidity meter is a high-precision instrument for measuring turbidity in various liquids. It is frequently used in water and waste water analysis, in the food and beverage industry as well as in the chemical and pharmaceutical industry. Thanks to its compact design and easy handling, it is ideal for mobile use. Compared to similar devices such as the WTW Turb® 355 IR portable turbidity meter, the Turb® 355 T offers excellent accuracy and reliability.
Technical details and functions
The Turb® 355 T works according to the nephelometric principle (90° scattered light) and uses a tungsten lamp as light source. This enables precise measurements in a range from 0 to 1100 NTU (Nephelometric Turbidity Units) and FNU (Formazin Nephelometric Units). The resolution varies depending on the measuring range:
- 0.01 NTU in the range 1...9.99
- 0.1 NTU in the range 10.0...99.9
- 1 NTU in the range 100...1000
The accuracy of the device is ±2 % of the measured value or ±0.1 NTU in the range 1...500 NTU and ±3 % in the range 500...1100 NTU. The repeatability is ±1 % of the measured value or ±0.05 NTU/FNU. The device has an automatic 1 to 3 point calibration and a response time of 14 seconds.
Other special features include:
- Calibration record
- Measured value memory
- RS 232 interface
- Date/time
- Data evaluation
- Optional rechargeable battery
The device operates in a temperature range of 0 to +50 °C and is powered by 4 MICRO (AAA) alkaline-manganese batteries, which are sufficient for more than 1,500 measurements.
