Digital Tensile Testing Machine

Test Method - IS 3400:2012 Part I

Feature –

  • Variable frequency 2 -speed control
  • Digital load indication
  • Capacity – 5000 N

Application – For determining the tensile and elongation properties for rubber compounds


Ozone Chamber


Test Method – IS 9573:2012

Ozone Chamber covers the estimation of the resistance of vulcanized rubber to cracking when exposed to an atmosphere containing ozone. The rubber specimens are kept under a surface tensile strain, and the ozone content or partial pressure in the test chamber is maintained at a fixed value. It provides precise and accurate ozone (O3) concentration environment for rubber and polymer testing

Application – It is used to evaluate the ozone ageing resisting performance of Rubber.

Fourier Transformation Infrared Spectrometer

Test method – ISO 4650:2012 (E)

Feature –

  • Real time, ratio-recording instrument with built in handling facilities
  • Continuous recording of infrared transmittance or absorbance of sample as a function of frequency to record spectra.
  • Minimum sample preparation required for testing.

Application – Qualitative identification and estimation of Compounds in polymer materials


Humidity Chamber


Test Method – IS 3400:2012 Part I

Feature –

  • Temperature upto 10 Deg C / 60 Deg C and humidity range 40% to 95% Rh
  • Microprocessor controller with LCD display and sensor for precise control of temperature and humidity.
  • Self-Diagnosis for errors
  • PC Compatible

Application – For conditioning of Rubber samples prior to testing

Profile Projector

Application – This instrument is used for precision dimensional analysis of soft rubber parts.
