WYK-Series DC stabilized power supply with international advanced "floating superposition type" technology developed from. Integrated electronic circuits by the step-down transformer, rectifier, filter, high power transistors and benchmark adjustment, sample amplification etc., dual independent output power can also be used in series or parallel. In series from the output voltage to track the main output voltage, maximum output current can be parallel to the sum of two independent output current. DC output ripple, high stability, voltage regulators, automatic conversion steady flow, flow over-current limit, short circuit protection and automatic recovery features, is the tertiary institutions, industrial enterprises, scientific research units and electronic maintenance personnel ideal DC power supply .

Setaflash Series 8 Closed Cup... The Setaflash Series 8 is an automated closed cup flash point tester with a temperature range of ambient +5 to 300°C (ambient +9 to 572°F). The instrument uses an electric hot wire ignitor (gas flame option).
There are two modes of flash point operation; Flash/No Flash and Ramp. The ramp mode increases the sample temperature at a rate of 2°C/min, allowing determination of a flash point in accordance with ASTM D7236 and IP 534. The dipping sequence occurs automatically every 1°C up to 100°C (every 2°C rise above 100°C), until either a flash is detected or the end of test temperature is reached. The ignitor uses a new electrical hotwire (a gas flame option is available).
