Portable Potentiostat – Galvanostat

Feb 03, 2018 

The potentiostat Model 2559, newest instrument of the potentiostats Amel series, can operate both as potentiostat that galvanostat with 9 current range, from 1 nA to 100 mA fs, and is particularly suited for ultra sensitive measurements, where currents are very low in the pico Ampere order or for field measurements due to its portability.

  1. It can be powered either by the powerline, with an appropriate power supply, or by a 12 V battery
  2. Built in an aluminum container which makes it particularly rugged.
  3. Given its small footprint is easily transportable so it can also be used for measurements in the field.
  4. It can be easily closed in the Faraday cage for very sensitive measures to interference of the power line.
  5. It can be connected to the PC via USB cable and thanks to the new VApeak software, has the ability to make different types of measures for both the electrochemical (batteries, electrode materials, corrosion) that electroanalysis (quantitative analysis for standard additions or with external standard).
  6. Possibility of performing impedance measurements using appropriate external interface specification

thincorrThinCorr: think local, be versatile

In many metal corruption analysis scenarios, extracting small samples of material from large components and bringing to the laboratory is simply impossible. In such situations measurements on site become the only option. Since the advent of very precise miniaturized electrochemical cells, Amel has developed his own on-site system, called ThinCorr, designed to get the same performance of a complete laboratory set, wherever you need.

A unique bundle for a double convenience

ThinCorr includes a miniaturized cell – EC Minicell – designed to perform localized electrochemical investigations on surface areas of the order of mm2. thincorrThe test component is the 2556 Amel Portable Potentiostat, designed on purpose to pair the EC MiniCell features.

Nice ’n easy to work with

The miniaturized cell has been designed in a way that the electrolyte can flow in proximity of the working electrode, avoiding concentration gradients and the corresponding polarizations. Within the body of the EC Minicell there are channels that allow the flow of the electrolyte and that contain a counter electrode and a reference electrode. At the nozzle of the cell there is a gasket that delimits the area of the working electrode, when the EC Minicell is pressed against a metallic surface. ThinCorr system is driven by a proprietary software via personal laptop.

Performance you’ll simply adore

  • EC Minicell is a miniaturized, resistant, handy, and complete electrochemical cell suitable for localized electrochemical measurements.
  • Measurements are carried out with the electrolytic solution flowing from the reservoir to the WE and then back to the reservoir in a closed circuit loop. Fluid flow favors the removal of reaction products from the WE region.
  • There are not specific constraints on the types of electrochemical tests that can be performed, e.g. cyclic voltammetry, coulometry, and localized electrodeposition, thanks to the 2556 dedicated Potentiostat.
  • ThinCorr is a handy, trustable and versatile instrument for a variety of electrochemical measurements.

  • Measures pH, mV, and °C/°FF
  • Automatic and/or manual calibration
  • Absolute or relative measurements
  • Measure maximun and minimun
  • Automatic or manual temperature compensation
  • Auto-Power-Off
  • Hold function to block reading
  • High precision

The HD 8705 is a combined instrument for taking precise measurements of pH, mV and temperature in the laboratory, on the field and in industrial systems.

Various types of electrodes for pH may be connected to the BNC connector, electrodes for measuring the oxidoreduction potential (ORP) or ion specific electrodes (ISE). The temperature probes of the TP870 series are optional (TP870 for immersion, TP870C for contact, TP870A for air, TP870P for penetra-tion). In pH measurements the temperature probe automatically compensates the electrode temperature coefficient. If the temperature pro-be is not connected, manual compensation is automatically enabled (with the “up” A and “down” V keys).

For measuring pH, mV and °C

HD8602 - Microprocessor Multiuse pHMeterThe HD 8602 is a combined instrument for measuring pH, mV and °C in the laboratory, in the field and in industrial plants.

The instrument is provided with a BNC connector for pH electrodes, electrodes for measuring redox potential (ORP) or specific ion electrodes (ISE). A socket for 0 4 mm banana plugs is provided for connecting a reference electrode independent of the measuring electrode.

Compared to a cable that cannot be detached from the instrument, the BNC offers the advantage of being able to use all the electrodes available on the market an especially those types which for cost reasons do not have a connector directly on the electrode. Furthermore, with the BNC connector it is possible to disconnect the pH measuring cable (ORP, ISE), so that temperature can be measured alone without the electrode connecting cable getting in the way.

The STS 4 temperature measuring probe is optional and is connected to the instrument by means of a 5-pole DIN connector. During pH measurements this probe automatically compensates the electrode temperature compensates the electrode temperature coefficient. If the temperature sensor is not connected, the temperature coefficient may be compensated manually. A mechanical push-button panel protected by a polycarbonate membrane offers the possibility of selecting the desired unit (pH, mV or °C).

Adjustment of asymmetry ( ~0> pH) and ( z slope) in pH measurements is also carried out on the push-button panel. During the calibration phase (CAL) the symbols on the display flash. To return to the measuring mode, push the CAL button again. The calibration data are memorized event when the instrument is turned off. When the HOLD button is pressed the reading on the display is blocked; when the HOLD button is pressed for the second time the instrument returns to normal operation (continuous updating of the reading). To turn the instrument off, press the OFF button.

The instrument will also turn itself off automatically after about 3 minutes if it is in the measuring mode. In the HOLD and calibration modes the instrument will not turn itself off. Automatic cut-off in the measuring mode may be avoided by shifting the jumper in the battery compartment.
