ELECTRICITY
Water electrolysis experiment device HG0130
Lab power supply HG3005
Multimeter TS15090 • voltmeter and ammeter • separate 10 A socket • battery-powered (battery not included)
An electrolyzer in the form of a cylindrical plexiglass container with a raised bottom with two banana sockets (+ and -) underneath. These are connected with electrodes threaded through rubber stoppers of respective colours placed in the inlets of two acrylic test tubes with
General specifications: • output voltage 0÷30 V, output current 0÷5 A • voltage and current stabilization • ripple noise 0,5 mV rms • simultaneous reading of amperage and voltage for each output • digital display (2 x LCD - 220V) • fan • LED indicator
A very accurate power supply with protection against high temperature, short circuit, overload and damage. The output voltage and current are controlled steplessly with coarse and fine knobs - separately for the output current and voltage. The device operates in „constant current” (CC) and „constant voltage” (CV) modes.

Galvanometer HG0070
This sensitive galvanometer is an educational tool which can be helpful in physical laboratories. An analogue meter is used to measure very low values of electric current. It is equipped with three sockets with clamps adapted to cables with forks or banana plugs. • 13,3 x 9,7 x 10,2 cm; weight: 165 g • measuring range: -300µA~0~300µA • supply voltage: alternating current 220 V, 240 V
