High input impedance amplifiers types Ex02, Ex04 and Ex06

Some applications require low electrical loading, requiring very high impedance measurement inputs. Examples are the use of Ph electrodes and ion-selective electrodes. Reference electrodes will have a much longer lifetime when connected to a high impedance input.

Ext-Ins offers specialized equipment able to buffer or amplify high impedance signals with negligible input current. The output can be connected to a data logger, voltmeter or other (voltage) monitoring equipment. The input impedance is more than 1 Tera-Ohms (10^12Ohms). The equipment is mounted in an practical enclosure and has all necessary protections for a reliable use.

Multiple versions are available:
Ex02- a single ended dual channel amplifier, with input range between -5 and 5V (new version), Datasheet Ex02
Ex04- a differential dual channel amplifier, with input levels ranging from -10 to +10 V, Datasheet Ex04
Ex06- a differential amplifier with input range from -50 to +50 V, Datasheet Ex06. this version has also a remake, the Ex06_MK2,
