ETT-3000  Automatic Flash Point Tester (open and closed)

Feature of this instrument
Original of a multifunctional furnace using a modular design, a host can simultaneously control multiple test furnace at the same time or time to test different samples;
The original disordered access capabilities, regardless of serial number of the test furnace interface any connection to the host, the host automatically identify the number of access to the test furnace. The host set aside three access port, access port number can be increased according to user needs;
The high-speed signal processor control, high-precision analog / digital conversion circuit, and reliable instrumentation, and test accuracy;
Electric ignition of the gas source, the auto-ignition;
Built-in barometric pressure sensors, atmospheric pressure automatic measurement, automatic calibration results;
Adaptive PID control algorithm to automatically adjust the heating curve according to the standard requirements;
Warming program sweep (openings), ignition, alarm, cooling, print the entire experimental process is done automatically;
With automatic fault detection and alarm functions. Sensor failure, the oil sample error, the temperature value, the instrument will automatically stop the test and alarm;
Built-in high-speed thermal mini-printer, print beautiful, fast, with off-line printing capabilities;
History with time stamp and store up to 255;
320 × 240 dot-matrix graphic LCD, touch screen operation, the screen saver function to prolong LCD life;
With standard the RC232 interfaces, and can connect with computer, easy to deal with the experimental data;
