ESAW EEC-10640 Potentiometers Error Detector Specifications High-quality servo-potentiometers of 360 shaft rotation Requires an external CRO for a.c. Studies Built-in signal and power sources 3% digit DVM for measurements

For investigating transpiration. Measures the uptake of water by a cut plant shoot. The cut shoot may be replaced by a porous pot filled with water which enables measurement of the rate of evaporation from a moist surface, thus giving indication of relative humidity. Comprises a capillary tube wi...

Apparatus to measure absorption of water by transpiring plants, Comprising a glass tube with upper end of straight limb closed with rubber stopper, lower end of the limb is fitted with a bored rubber stopper to take length of capillary tubing.

A reservoir with 3 hole stopper for holding a graduated capillary tube 390 mm long, a short length of 10 mm dia glass tube to hold plant shoot and a funnel of 25 ml with a stopcock.

To demonstrate rates of transpiration and of water absorption by a cut shoot, with a graduated capillary tube bent down at right angle at one end with a small orifice and having water reservoir with glass stopcock and the end tube with rubber stopper for the plant shoot at the other end, on base.

On base, with jar for seeds, pointer and scale.
