Protective clothing worn near molten metal faces a threat that is difficult to simulate: droplets at over 1000°C striking fabric at speed. The Molten Metal Tester recreates that impact under controlled conditions, generating metal droplets of defined mass and frequency, directing them onto a tensioned sample, and measuring the temperature rise on the back side of the fabric. This Molten Metal Tester is built for protective clothing manufacturers, third-party PPE testing laboratories, and research institutions that need ISO 9150 and EN 348 compliance data without assembling a custom oxyacetylene rig.

Key Benefits: Repeatable Splash Data Without Hand-Built Rigs

Standards-Matched Droplet Generation

The Molten Metal Tester produces droplets at 0.50 ± 0.05 g and 20 drops per minute, matching the mass and frequency windows specified in ISO 9150 and EN 348. The wire feed rate of 10 ± 1 g/min keeps droplet production steady across the test, so each sample sees a comparable thermal load.

Back-of-Sample Temperature Measurement That Alerts in Real Time

The armoured platinum sensor sits in direct contact with the sample back, with a thermal response time of ≤0.5 seconds. The system displays temperature rise against droplet number and time, and triggers an alert when the guide slot exceeds 250°C or the back temperature rise reaches 40 K. You do not need to watch a separate readout to catch the failure point.

Three-Dimensional Sample and Guide Adjustment

The funnel guide angle is adjustable, and the holder moves in three dimensions. This lets you position the droplet impact point precisely on the sample and match the geometry your standard requires, rather than accepting a fixed drop location.

Software-Integrated Data Capture

The included professional computer software logs the temperature rise, droplet count, and timing throughout the run. Your test records are captured digitally from the first droplet, which simplifies reporting for certification or supplier qualification.

Solving the Problems That Slow PPE Qualification Down

Struggling to produce droplets at a consistent mass and frequency?
The wheel-driven wire feed and fixed welding tip geometry hold droplet weight at 0.50 ± 0.05 g and frequency at 20 drops per minute. The oxyacetylene flame melts the wire under regulated feed, not manual timing.

Concerned about missing the moment the sample fails?
The system alerts automatically when the back temperature rise hits 40 K or the guide slot exceeds 250°C. You do not have to monitor a separate thermometer while the test runs.

Tired of repositioning samples by eye between runs?
The three-dimensionally adjustable holder and funnel guide let you set the impact point and sample position repeatably. The 175 g pre-tension keeps the fabric in contact with the sensor.

Need test records that hold up to ISO 9150 or EN 348 review?
The software captures temperature rise, droplet count, and timing throughout the run. The instrument geometry follows the standard dimensions, so your setup documentation matches the method.
