Gradient Heat Seal Tester RTD-R2

Product catalog summary

Overview
The Labthink RTD-R2 Gradient Heat Seal Tester is designed to efficiently determine heat seal thresholds. It features up to 5 jaws with independent temperature control, allowing for a temperature gradient on the film. The device can be equipped with heated upper and lower sealing jaws, providing heat from both sides of the materials.

Standards Compliance
The instrument conforms to ASTM F2029, which is the standard practice for making heat seals to determine the heat sealability of flexible webs as measured by seal strength.

Sealing Temperature
The tester uses Digital P.I.D. temperature control technology to achieve defaulted temperatures efficiently and accurately. It displays temperature values digitally for ease of use and allows for independent upper and lower sealing temperatures.

Sealing Pressure
Controlled by a microcomputer, the device features an electronic pressure timer with a digital display of pressure values. It includes a high-precision pressure sensor and dual underneath and closed-loop gas cylinders to ensure even pressure on the sealing surface.

Dwell Time
The tester includes an electronic timer with a digital display for dwell time, designed to measure accurate dwell time on the sealing sample.

Sealing Jaws
The device can test 5 groups of specimens at different temperatures simultaneously. It ensures even temperature distribution across the sealing jaws, which can be customized into different shapes. It includes a safe use caution sign and a pedal switch for safe test operation, along with a standard RS232 port.
