The J-221 Meter complies with MIL STD 45662-A and can be found in MIL-I-6868D. Each meter features two scales for low and high-intensity readings. For remote readings, a four foot (1.2m) cord connects the sensor to the meter. Two scales measure a wide range of intensity. An infrared filter assures accurate readings when measuring light sources producing infrared radiation. The 5X attenuation screen can be used for very high-intensity lamp measurements.
