Intermediate Temperature System

A compact temperature chamber enabling temperature control from - 35 °C through to + 150 °C. The device has been designed to accommodate Bio-Logic sample holders such as leak-tight sample holders (CESH).

A compact temperature control solution for electrical characterization

The Intermediate Temperature System (ITS) is a Peltier effect based temperature control unit.

The ITS is a compact temperature chamber with a small laboratory footprint. It enables accurate temperature control from – 35 °C to + 150 °C and is designed to accommodate Bio-Logic sample holders such as leak-tight sample holders (CESH).

The two PT-1000 temperature probes provided with the ITS, ensure accurate measurements and temperature control. An optional PT-1000 probe enables direct measurement of the actual sample temperature.

The  ITS  is highly suitable for determining the characterization of materials’ properties by impedance measurements, under controlled temperatures. It has been adapted for use in controlled atmospheres (up to 2 bar relative pressure) with CESH.

An oxygen and moisture-sensitive sample can be prepared in a glove box, placed in the CESH and then installed in the ITS. The ITS is compatible with the MTZ-35 impedance analyzer and with Bio-Logic potentiostats/galvanostats/FRAs, facilitating the setup of experiments for Bio-Logic system users.

The ITS can be controlled via a USB cable from your computer using MT-Lab® software. A wide range of temperature control modes is available with MT-Lab® software resulting in intelligent temperature management capability.

The ITS is also controllable via EC-Lab® software using the auxiliary inputs/output of Bio-Logic potentiostats. Both the MT-Lab® and EC-Lab® interfaces provide protocols and data graphing for impedance measurement and data processing.

The impedance data can be fitted using the powerful Z Fit tool available in both software packages.

 

An intuitive and comprehensive software

MT-Lab® is an intuitive and user-friendly software dedicated to the control of Bio-Logic’s impedance analyzer, the acquisition of the impedance data and the temperature. It also allows the control of many temperature control units:

  • High-temperature furnace (HTF-1100)
  • Intermediate Temperature System (ITS)
  • Temperature control systems using Eurotherm 22xx and 35xx series controllers…

Specifications

  • Temperature range -35 °C to +150 °C
  • Temperature accuracy ±0.3 °C
  • Computer Interface USB 2.0
  • Mains voltage 115 V/230 V 50/60 Hz
  • Power consumption 250 W
  • Dimension 400 x 313 x 385 mm (L x W x H)
  • Weight 8 kg

In the ITS’s brochure, two PT-1000 are mentioned to be provided with the ITS? I received only one PT-1000. What about the second PT-1000?

Two PT1000 are provided by default with ITS. The first one (not visible) is installed inside the ITS for measuring the ITS temperature and the second one is expected to be connected to CESH sample holder.

I cannot connect ITS to MT-Lab® software?

First check if the ITS is seen by the operating system of your computer by clicking on “Control Panel” > “Device Manager”> “Ports (LPT & COM)”. If you see “communication device class ASF example (COM X)”. This means that the USB driver is working. In case you cannot see it, that means that the ITS driver was probably not well installed. Re-install MT-Lab® software and the ITS driver.

Can I use ITS with another impedance analyzer?

ITS is controlled by MT-lab® software only if MT-lab software is connected to MTZ-35 impedance analyzer. It can also be controlled by EC-Lab® software connected to potentiostat.

Can I control the ITS manually?

No

How can I control ITS with a potentiostat?

An ITS can be controlled by a Bio-Logic potentiostat through the analog output using a DB9-DB9 cable. The user has to load Temperature Control (TC) protocol and to go to “External Devices” tab of EC-Lab, select “TCU” in the device type and ITS as a device name in order to control the temperature of the ITS. More details can be found in the Operating manual for ITS.

I performed impedance measurement at various temperatures with MT-Lab® software. The temperatures displayed on the impedance plots are the setpoint temperatures. How can I access to the actual temperatures at which the impedance measurements have been performed?

You can access to the actual sample’s temperature at which the impedance measurement has been performed by selecting “Data” tab in the graphic window of MT-Lab® software and then select “sample temperature” column.

How can I access to the coordinates (frequency, phase, etc) of a measured point of impedance diagram?

You can access to the coordinates of a measured point by clicking on “Data view”. A data view window is displayed. In case of multi- temperature graphs, select the graph at the desired temperature and the impedance representation and then click on the point you want to display the coordinates. “Data view” is disabled during data acquisition.

I bought an additional PT1000 to monitor the temperature of the sample. Can MT-lab® control the temperature versus the Tsample or it still control the temperature versus the Tcell even if a second PT1000 is connected to ITS?

MT-Lab controls the temperature versus Tcell even if a Tsample is displayed on the temperature plot. If you want to control the temperature versus the sample temperature the PT1000 placed in the central hole of the CESH, close to the sample has to be plugged in the “TCell” Lemo connector on the rear panel of the ITS.

I use In-plane CESH with interdigitated electrode. What is the nominal constant of this electrode?

The nominal constant of the interdigitated electrode is 0.2 cm-1. This constant can be determined using a standard solution. More details can be found in the TN#06 – Calibration of a sample holder.
