The ZF-19RL portable industrial LED film viewer is a new product developed by our company for the NB/T47013.2-2015 "Non-destructive testing of pressure equipment" and GB/T 19802-2005 "Industrial radiography film viewer" standards. product. The light source adopts high-power LED surface light source, so that it still has a high uniformity under high brightness, and can clearly observe and evaluate the film with a blackness of 0-4.5, which meets the needs of daily use and has a theoretical working life. Over 50,000 hours.

Features:

1. LED aluminum substrate, low-resistance radiator, internal fan, metal paint shell quadruple heat dissipation, effectively reducing the working temperature of the shell;

2. The method of PWM pulse width modulation is adopted to realize 3%-100% ultra-wide range stepless dimming, which can be adjusted arbitrarily according to needs;

3. Use manual and foot switch control to improve the convenience of operation and meet different operating habits;

4. The shell is designed with a stainless steel pull ring, which is convenient to carry;

5. Tailor-made external power supply can be used for normal film review when there is no 220V in the field;

6. Long life, working life is more than 50,000 hours, which is 10 times the brightness of ordinary fluorescent lamps. With special overcurrent and temperature protection devices, the life of the light source is further improved;

7. Fast start-up. Due to the fast start-up characteristics of LEDs, the light source has a fast start-up time, which is different from fluorescent lamps and does not require warm-up time, and the number of starts will not affect the life of the light source;
