The NIOS series of nanomechanical testers is available in three platforms: NIOS Compact, NIOS Standard and NIOS Advanced. Depending on the size of the selected platform the device may comprise one, two of three of the following measurements modules:
-
Wide-range nanoindenter
-
Scanning nanomechanical tester
-
Atomic force microscope
-
Optical microscope
Special modification of NIOS Standard instrument can be equipped with three-axis heterodyne interferometer used for application in linear displacements nanometrology.
Depending on the type of the platform, one extends the capabilities of the instrument with additional options such as a lateral force sensor, heating stage, high load option, acoustic emission sensor, reciprocating wear module, etc.
Wide-range nanoindenter module
Purpose:
The wide-range or instrumented nanoindenter module is designed to measure the mechanical properties of various materials using a wide range of applied loads and depths. The range of application spreads from sufficiently hard materials (sapphire and harder) to quite soft polymeric materials, plastics and some sorts of rubbers. This capability to conduct a measurement for the different types of materials is provided by the big displacement range of the shaft and by the method of load application.
This module is also used for the wear resistance measurements as well as for the scratch testing, which can be used for the mechanical and adhesive properties measurements. Using lateral force sensor it is possible to measure a lateral force and a friction coefficient.

Modes and methods:
• Instrumented indentation in accordance with ISO 14577
• Vickers hardness measurements
• Scratch tests (hardness measurements by scratching) with constant or variable load
• Dynamic stiffness measurements
• Beams and membranes stiffness measurements
• Hardness and elastic modulus dependency of the indentation depth
• Automated mapping of two- and three-dimensional hardness and elastic modulus distribution over the surface within the area of 50x50 mm
• Adhesion characterisation by the scratch method
• Measurements in liquids
• Additional option for the loads up to 30 N
Technical data:
The indentation module has 4 basic operating modes:
















Additional units and sensors
NIOS nanomechanical testers have a lot of additional units and sensors. This extends the functionalities of the measurement system and provides a maximum level of device adaptation for customer's needs.
Measurement platform final configuration is selected depending on the customer's research tasks.
In order to deal with unusual research tasks it is possible to create new units, modify existing units and sensors and install on NIOS units from other manufacturers.

IN-situ and EX-situ NIOS Nanomechanical Testers
About NIOS
The technologies underlying NIOS nanomechanical instruments have been developed by russian materials scientists and engineers since 1995. All technical solutions employed on NIOS instruments are protected by patents under Russian Federation.
The modular design of NIOS series allows end-users to configure a nanomechanical tester specifically for their needs and requirements. Configurations of NIOS nanomechanical tester can consist of the following modules:
-
Wide-range nanoindenter
-
Optical Microscope
-
Atomic Force Microscope
-
Scanning nanomechanical tester
-
Electrical Properties Measurement
-
Lateral Force Sensor
-
In-situ Topography Imaging
-
Heating Stage
NIOS Advanced is the flagship model which implements more than 30 different measuring techniques covering all types of physical and mechanical properties measurements at the submicron and nanometer scale.
With NIOS control software a high degree of automated measurements can be achieved allowing the end-user to configure any set of measurements recipes to be performed without operator intervention. This feature is particularly useful for the technical control of the materials quality. With this added functionality, NIOS can be used for research work as well as for industrial applications.
