Computerised VSP & HDT Apparatus
Computerised VSP & HDT Apparatus (Product Code: SLE/ET/05) is a heated-bath testing instrument used to find the Vicat softening point (VSP) and heat deflection temperature (HDT) of plastics in polymer testing and quality-control laboratories. Loaded specimens are heated from ambient to 300 °C at 120 °C/hour or 50 °C/hour while sensors with 0.01 mm resolution follow them, and 2 to 6 stations can be specified. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among its test and measurement instruments in India.

What Is the VSP & HDT Apparatus Used For?
Both tests show how a plastic behaves as it warms under load. In the Vicat test a flat-ended needle rests on the specimen under a set load, and the bath temperature at which it penetrates a specified depth is taken as the softening point; in the HDT test a bar is loaded in bending, and the temperature at which it deflects by a specified amount is recorded. The microcontroller shows both results directly, and the PC software plots penetration or deflection against temperature.
Material suppliers, moulders and polymer courses use these results to compare grades and judge the temperature limit of a moulded part. Choose the heating rate your method requires, build the load from the 5 g to 2000 g weight set, and zero each sensor before heating begins. With several stations, specimens from one batch run side by side under identical heating, which makes the unit a productive choice among polymer laboratory instruments in India.
What to Specify When Ordering
- Number of stations, from 2 to 6
- Heating rate required: 120 °C/hour, 50 °C/hour or both
- The loads your method needs, so the 5 g to 2000 g weight set can be checked against it
- Whether a PC and printer for graphs and reports should be quoted (confirm with us)
- Quantity and delivery location

Frequently Asked Questions
What do VSP and HDT stand for?
VSP is the Vicat softening point and HDT is the heat deflection temperature. The Computerised VSP & HDT Apparatus measures both, recording the temperature at which a loaded plastic specimen penetrates or deflects by a set amount as its bath heats up.
What temperature range and heating rates does it offer?
The Computerised VSP & HDT Apparatus heats from ambient to 300 °C at either 120 °C/hour or 50 °C/hour, so the rate can be chosen to suit the test method your laboratory follows.
How many specimens can be tested at once?
The Computerised VSP & HDT Apparatus is offered with options from 2 to 6 stations, so two to six specimens can be tested in a single heating run. State the number of stations you need when you enquire.
Which weights are supplied with the apparatus?
A set of weights ranging from 5 grams to 2000 grams is supplied with the Computerised VSP & HDT Apparatus for applying incremental loads to the specimens at each station.
How fine are the displacement sensors?
Each sensor on the Computerised VSP & HDT Apparatus has a range up to 10 mm and a resolution of 0.01 mm, which is fine enough to follow the small penetrations and deflections these tests measure.
Who supplies the Computerised VSP & HDT Apparatus?
The Computerised VSP & HDT Apparatus is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to polymer, packaging and engineering laboratories in India and international markets.
Is a calibration certificate available?
Calibration-certificate availability for the Computerised VSP & HDT Apparatus, including its temperature and displacement sensors, should be discussed with us before ordering. Send your documentation needs through the contact page for confirmation.
