Standards

The QualiHDT 300 series of HDT/vicat heat deflection testers enables material laboratories to verify how solid polymer specimens react to elevated thermal conditions. By switching the specimen holder, your team can examine both heat distortion and Vicat softening point values from ambient room temperature up to 300℃. This configuration supplies direct mechanical data for quality teams checking rigid plastics across industrial production facilities.

Room temperature to 300℃ range
0.001 to 3.000 mm deflection
1, 2, or 3 stations
0.445 MPa or 1.82 MPa

Product Applications & Operating Environments

The QualiHDT 300 operates within indoor research rooms, industrial inspection areas, and third-party hdt testing lab spaces with single phase 220VAC or 110V power connections. The hardware evaluates structural polymers that retain their rigidity at 27°C, accommodating ASTM test bars measuring 127 mm by 12.7 mm by 6.35 mm as well as ISO samples measuring 120 mm by 10 mm by 4 mm or 80 mm by 10 mm by 4 mm.

This equipment serves industrial sectors evaluating rigid polymers, technical textiles, and advanced synthetic materials:

Technical textiles and performance fabric reinforcement compounds
Advanced materials and synthetic polymer compounding
Aerospace component polymer screening
Defense hardware resin verification
Healthcare plastic device assessment
Rubber manufacturing facilities requiring high temperature deflection records

Key Features

Dual Purpose Fixture: Operators can swap the contact holder to carry out either standard heat deflection or Vicat softening trials without moving to a separate heat deflection test apparatus.
Automated Weight Selection: The control panel lets you choose ASTM or ISO test guidelines and enter precise sample dimensions, prompting the system to calculate the required physical weights automatically.
Dedicated Sensor Instrumentation: Every station features an independent temperature probe and displacement sensor, giving your personnel real-time data visibility across all active sample locations.
Controlled Thermal Shutdown: The heating element switches off and the water cooling system turns on the moment a specimen meets its target deformation benchmark (0.254 mm for ASTM, 0.32 mm for ISO edgewise, or 0.34 mm for ISO flatwise).
Data Handling and Export: The terminal saves 30 test records internally, and inserting a USB flash drive allows you to log the entire thermal run and export raw values in CSV format for analysis.

Interface Introduction

Weight Calculation Able to switch test standard ASTM or ISO and enter the specimen dimension for load auto-calculation.	Vicat Heat Deflection Able to switch in to Vicat heat deflection test mode. Test standard can be switch into ASTM or ISO Support with specimen dimension enter for load auto-calculation.
Test Setting Built-in standard test condition and standard test process can reduce the test error. Able to support with special test condition setting.	Test Display Able to test 6 specimen to test at the same time. Each sample holder has its own temperature and displacement measure tool. Display will show the real-time test situation. When reaching deflection value, it will stop and start cooling system.
Test Process Exclusive test operation leading can make it easier to use and help user to reduce the man-made improper operation.

Result Saving 1. Display can store 30 test data and able to save the result with USB.

2. Pluging in the USB while testing can record the whole test process and save the raw data in CSV format for anlysis.
