Cyclic Corrosion Test Chamber

Cyclic Corrosion Test Chamber

Corrosion Test is an accelerated corrosion test that produces a corrosive attack on the samples so as to predict their corrosive behavior under various environmental conditions as well as their suitability in use as a protective finish.

An accelerated corrosion test chamber performs the test by creating different environmental conditions such as Salt Fog, Salt Spray, Humidity & dryness in order to simulate the effects that a material will see under real life.

Cyclic Corrosion Test is popular because it is cheap, quick, well standardized and reasonably repeatable.

Whether you are new to corrosion testing or have been conducting test for years, you will find DnG Technologies equipments easy to use and operate. They are designed to provide the accuracy and flexibility necessary to meet today's industrial testing standards.

Tensile Testing Machine

Tensile Testing Machine

Tensile Testing Machine finds its application in determination of the tensile strength and elongation of variety of raw materials such as rubber, leather, fabric, plastics, Belts, wires etc.

The machine works on constant rate of traverse principle in which one end of the test specimen is held in a stationary grip while the other end is made to move at a known fixed speed. The load exerted on the stationary grip is sensed by a load cell and indicated by a digital load indicator. The load directly indicated in kilograms or Newton. The elongation of the test specimen is measured on a digital indicator.

Isoperibol bomb calorimeter

Isoperibol Bomb Calorimeter

DNG Series of Isoperibol Bomb Calorimeters features an integrated platform based Bomb Calorimeter that combines all the features required for Calorific Value measurements of Solid and Liquid samples along with an Integrated Closed Loop water Chilling and circulating system.

The special feature of the instrument is that it does not require any special chemicals or water additives for the operation of the instrument. It is robust and highly durable and has proved its application in a wide range of applications and environments.

The instrument is designed with the latest Combustion Bomb, Auto Oxygen Charging and Venting System and Auto Lift System. The operator’s job is limited to putting the Oxygen Bomb with sample on the Bomb Hook. The instrument is designed to take over the operation thereafter.

All processes in the experiment are fully automatic. There is no requirement to either fill Oxygen externally or Relief Air or Measure Water or Adjust the Water Temperature etc. thereby reducing the workload of the operator and the errors associated with it.

Choice of Dual Operating Modes give Additional choice to customer to configure the experiment as per their own requirement. The precision mode takes a slightly longer time compared to the Predictive Mode.

A highly accurate measuring and dosing system is used to measure and fill water in the Calorimeter Vessel. This latest design ensures high repeatability and accuracy.

The customer has a choice of either a Solid State Peltier based Chilling system or a more heavy duty Compressor based chiller as per their requirements. The system automatically determines the cooling requirement and adjusts the circulating system accordingly. The same water is reused in a closed loop water circulation system.
