pH 205 starter set

Precise measurements of pH and temperature for small sample volumes

The pH 205 is a handy insertable meter for measuring pH and temperature. It features automatic temperature compensation. This device is well suited when only small samples are available for measuring, such as for a small partition in a cultivation system. It can also be used to measure in solutions. The insertable probe tip is embedded in impact-resistant plastic. The tip is not sensitive to contamination (thanks to the hole diaphragm) and can be easily replaced. The device also features an illuminated display and buttons with acoustic feedback. Single, double or triple point calibration is possible. The calibration process automatically detects the end value.

Bambach-BLUMAT plug-in tensiometer

A tensiometer is used to measure suction tension. The porous cell of the tensiometer uses capillary action to transport water outwards into the drier soil. A negative pressure is then created within the closed pipe. This negative... ...more Topseller
