Voltmeters
Voltmeters present a convenient and easy-to-use tool for measuring the voltage. The meters can also be used to calculate the potential in direct-current or alternating-current circuits, and voltages developed in electrochemical or voltaic cells in chemistry applications. Models may offer audible or visual indication of voltage readings. The sensitivity ranges can be adjusted to sense particular voltage levels. All voltmeters are portable and are constructed from durable materials.

Linear Stimulus Isolators, A395
Supplier: WORLD PRECISION INSTRUMENTS LLC
A395 generates a user-defined output current of wave shape; DC, AC, pulse and combinations. Battery operated, photoelectrically isolated from the input voltage drive, the instrument regenerates output currents which are linearly proportional to the analog voltage waveforms provided by your D/A converter or signal generator.

High Current Stimulus Isolators, A385
Supplier: WORLD PRECISION INSTRUMENTS LLC
The A385 is an optically isolated current source, which can generate up to 100 mA of unipolar or biphasic constant current pulses or DC. Pulse duration is controlled manually or by an external 5 V command. Output current amplitude is determined by a 3-digit 10-turn potentiometer. Maximum output voltage between the stimulating electrodes is +36 V.
