eDAQ produces a variety of amplifiers designed to work specifically with e-corder units. eDAQ Amps become an extension of the e-corder system, and are fully controlled by software. All eDAQ Amps draw power from the e-corder unit via a proprietary ‘I2C’ interface which also facilitates software recognition and control of the amplifier operation. You can operate multiple eDAQ Amps on the one e-corder unit.
Quad pH/mV Amp
The Quad pH/mV Amp consists of four high impedance electrometer type pH/mV amplifiers. It is designed to operate with e-corder systems, and can simultaneously record signals from up to four pH, ion selective and potentiometric redox (ORP) electrodes. Each amplifier can be used with either combination, or half cell electrodes with separate reference electrodes. The amplifiers are galvanically isolated to minimize interference from ground loops or other nearby sensors.
The unit can also be used with other high impedance sources up to ±2 V, requiring electrometer input.
Quad Tc/mV Amp
The Quad Tc/mV Amp can simultaneously record signals from up to four thermocouples. The thermocouple inputs are individually galvanically isolated to minimize interference from ground loops or other nearby sensors. Sensor calibration can be performed with the Thermocouple extension.
The unit can also be used to monitor other voltage sources (up to ±50 mV), requiring electrometer input
The C4D Amp is a high sensitivity capacitively-coupled contactless conductivity detector (C4D) for capilliary electrophoresis (CE) and ion chromatography (IC) systems, using PowerChrom system, or e-corder data acquistion systems. It is supplied with a suitable headstage, usually the ET120 C4D Head (for CE or IC), or optionally the ET121 C4D Microfluidic Platform for use with microfluidic channel chips. Excitation frequency and amplitude can be optimised by the user for maximum signal sensitivity. Suitable for use with e-corder or PowerChrom systems for data collection.
The pH Pod is a fully software-controlled miniature amplifier suitable for use with pH, ion selective, and potentiometric redox (ORP) electrodes with internal reference cells (combination electrodes).
Ideal for student experiments monitoring solution pH, or redox potential.
The Conductivity Pod is a fully software-controlled miniature amplifier suitable for use with laboratory conductivity cells.
Ideal for student use in monitoring solution conductivity levels.
The RTD Pod is a fully software-controlled miniature amplifier suitable for use with 100 ohm platinum RTD probes. It can be used in normal or differential mode. In differential mode an offset can be applied, via the front panel knob, so that very small temperature fluctuations can be measured.
The Thermocouple Pod is a fully software-controlled miniature amplifier suitable for use with K- and T-type thermocouples. It can be used in normal or offset mode. In offset mode a temperature offset can be applied, via the front panel knob, so that very small temperature fluctuations can be measured.
Ideal for student use in thermochemistry including melting and boiling point determinations, and calorimetry experiments.
A compact signal conditioner for use with an e-corder unit, providing a continuous AC coupled signal from PCB Piezotronics ICP® accelerometers, microphones, vibration and related sensors requiring a constant current supply.
