Highly accurate turbidity standards composed of suspended microspheres, suitable for instrument calibration and control of all turbidimeters. Stable, shelf life 2 years (from date of manufacture). NIST traceable, US EPA approved and tested in accordance with ISO 7027.
100 ml HDPE bottles.

Two ranges available:
Range Ratio for Ratio Turbidity Measurement instruments (measurement of the light scattered by the sample at a 90° angle to the incident light, plus additional angles – different detectors).
Non Ratio for Non Ratio Turbidity measurement instruments, which will measure the light scattered by the sample at a 90° angle to the incident light (one detector).

Benchtop water bath made of high-quality, corrosion-resistant and easy-to-clean stainless steel for the working chamber and housing.
Temperature range: + 5 °C above ambient up to 95 °C; Accuracy: 0.1 °C
Volume: 10 liters
Interior:
Perfect for everyday laboratory use: The high-quality stainless steel tank with rounded corners is easy to clean and can be completely emptied using the standard drain valve without leaving any residue.
Compact and ergonomic design: The Memmert WTB fits on any laboratory bench.
Controller: Intuitive 3.5″ color graphic display with touch screen.
Timer: Digital from 1 min. to 99 hours 59 min., visual and acoustic.
Controller: Digital display of set and actual temperature and program (remaining) time.
Control:
