An intuitive and comprehensive software
MT-Lab® is the user-friendly software package 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
Open-circuit & short circuit compensation.
MT-Lab® software is provided with a compensation protocol for the compensation of residual impedance due to cell cables and/or sample holders
Temperature control management
MT-Lab® software includes a temperature control interface with five temperature modes in the temperature range -40°C to 1100 °C. The setpoint temperature range, the temperature ramps are adapted to the specifications of the TCU connected to MT-Lab® software. Up to three temperatures can be managed and acquired by MT-Lab® software: TTCU, TSample holder and TSample.
A complete graphic package
MT-Lab® is an easy to use software. The settings and graphs displayable on one screen view. The software provides automatically the processed electrical parameters like the electrical conductivity (σ), the electrical resistivity (ρ), the complex permittivity ɛ* and dielectric loss tangent (tan δ). It also includes ZFit, the powerful Equivalent circuit modeling tool used for modeling EIS data with equivalent circuits.

MT-Lab® software release notes are listed below:
MT-Lab® v1.21 (online May. 11, 2017)
Optimization of MT-Lab temperature control algorithm with HTF-1100 furnace. During a temperature ramping (heating) the measurements take less time than previously. Loading of the setting made by HTF-1100 furnace is now possible with offline MT-Lab. The floating window “Temperature control” was renamed as “temperature plots”. The unit on the time axis (x axis) is now hh:mm instead of date.“Permittivity” plot was removed from “Bode” tab of the graphic window.
The bug of “Hold last temperature” feature observed in the version 1.20 was fixed Minor bug corrections
MT-Lab® v1.20 (online July. 01, 2016)
Control of the Intermediate Temperature System through USB connection. Management of the temperature of the ITS, CESH and the sample
Temperature display with 1 digit after decimal (instead of 2 digits) in temperature plot window. Furnace setpoint is replaced by Control Unit Setpoint in the temperature plot window. Furnace Temperature Unit is replaced by Control Temperature Unit in the temperature plot window and data.
MT-Lab® v1.13 (online September. 30, 2015)
New ZFit module inspired from our popular EC-Lab software. Improved GUI. More functionalities (ZSim, Multi-cycle, more circuit selection).
MT-Lab® v1.12 (online December. 02, 2014)
Management of New temperature controller from Eurotherm: model 22xx and model 35xx.
Possibility to program temperature steps in two modes: cyclic mode and advanced mode. Option at the end of a temperature cycle to select between holding the last temperature value or returning to 0°C. Temperature is added and saved in the impedance data file. A programmable soak time has been added after the stabilization phase. Negative temperature values can be set in the temperature list if supported by the temperature controller.
Size of the settings window corrected. Scroll bar to scroll down the settings added. Setpoint to 0°C fixed.

MTZ-35: instrument/accessory set-up (video tutorials )
Which communication port should I connect the MTZ-35 to?
When you install MT-Lab® software, the driver of the MTZ-35 is automatically installed and two virtual communication ports are generated. To access to these communication ports go to control panel>external devices> ports(COM & LPT). You will see two virtual communication ports “USB l serial port (COM N)” and “USB l serial port (COM N+1)”. Select the one with the highest number (COM N+1).
Which communication port should I connect the HTF-1100 to?
First the HTF-1100 has to be connected to the MTZ-35 using the DB9-DB9 cable provided. Then, on MT-Lab® software, open “Configuration” window and select the appropriate communication port and click on the “connect” button. The appropriate communication port can be obtained at “Control Panel”> ”Device Manager”> “Ports (COM & LPT). You can see two virtual communication ports “USB serial port (COM N)” and “USB serial port (COM N+1)”. Select the one with the lowest number (COM N) to connect the furnace to MT-Lab® software. More details can be found in Installation and User Manual for MTZ-35 & its accessories.
I cannot connect the HTF-1100 to any communication ports?
As stated in answer No.2, the HTF-1100 has to be connected to the lowest communication port number generated by MT-Lab®. However, the HTF-1100 does not accept communication ports with a number higher than 9. The HTF-1100 furnace can connect only via communication ports between 1 and 9. If only communication ports with a number higher than 9 are available, the COM port number must be changed and lowered to a number lower than 9.
I performed impedance measurements at various temperatures with MT-Lab® software. The temperatures displayed on the impedance plots are the setpoint temperatures. How can I access the actual temperatures at which the impedance measurements have been performed?
You can access the actual sample’s temperature at which the impedance measurement has been performed by selecting the “Data” tab in the graphics window of MT-Lab® software and then select “sample temperature” column.
How can I access the coordinates (frequency, phase, etc) of the measured points on an impedance diagram?
You can access the coordinates of the measured points by clicking on “Data view”. A data view window is displayed. In the case of multi-temperature graphs, select the graph and the impedance representation and then click on the point for which you wish to display the coordinates. “Data view” is disabled during data acquisition.
