Ultra Low Chamber (Deep Freezer)  
 Ultra Low Chamber (Deep Freezer)

The Ultra Low Temperature Freezers are equipped with special air cooled compressor and CFC free refrigerators to give the efficient cooling and flow in the cabinet. High capacity air cooled condensers with aerodynamically shaped fans and washable condense filter keep fine free of dust to maintain utmost cooling efficiency.

Size : 18" x 18" x 18", Chest type freezers with temperature upto minus 40 degree C.

  • Accurate temperature control & holdover capability.
  • Thick polyurethane insulation of 50 - 80 mm.
  • Minimum power consumption.
  • Digital electronic temperature controller cum indicator allows for easy readability.
  • Durable stainless steel interiors aid in maintaining temperature and makes cleaning easy.
  • Outer is made of Galvanized sheet finished with epoxy paint.
  Digital Tensile Strength Tester

Digital Tensile Strength Tester for plastic, rubber & metal is based on the Constant Rate of Traverse (CRT) principle. The sample is held between two jaws, the upper one is a stationary jaw while the other end is made to move at a known fixed speed with the help of Motor, Gear Box and Lead Screw arrangement (75mm or 300mm per minute).

The load exerted on the Stationary jaw is sensed by a sensor connected with load cell which directly indicates the load in Digital form in kgs. The Elongation is digitally displayed.

Conditioning Chamber  
 Conditioning Chamber

The PRESTO Conditioned chamber is a ideal environmental chamber with the latest technology used to create the designated temperature. It has the lowest heat loss ratio due to high quality of insulation with imported glass wool. The chamber has a sealed compressor unit for high speed 'almost instant' cooling. Ergonomics and user ease are given a lot of importance while designing the system. It has complete DIGITAL controls.

Technical Specifications:
Size 18" X 18" X 28"
Humidity Range 65% - 95% (tolerance of +/- 2% RH)
Temperature Range Ambient to 65 deg.C

 Digital Tensile Testing Machine

The Presto Digital Tensile Strength Tester is electrically operated and is used to check the physical Impurities. It is basically vertical type, limit switches are incorporated for both the direction so to limit the traveling range. The accuracy of the machine is with in permissible limits as par IS:1828.

The test specimen is held between two grips the upper one of which is connected to the load indicating arrangement while the lower moves down at constant speed with the help of a motor operated screw. The elongation is measured as the displacement of the lower grip. The equipment is designed to test as per Indian and other international specifications.

Models available from 500 kg to 10,000 kgf.
