Features:
1. Using a silicon photocell detector with good stability, light resistance and impact resistance, it can achieve accurate photometric measurement after strict visual correction.
2. Wide measurement range, can measure 0.01-39990cd/m2 without dimmer
3. Digital display, with good indication reproducibility, data latch and peak value latch functions;
4. The power consumption is extremely low, and the 9V laminated battery can be used continuously for 100 hours;
5. Small light metering probe, measuring angle <10O;
6. Small and easy to carry, easy to use.
