Photo-Meter 1 (PM1)
With strap and case. Reads from 0.01 to
99,900 in footcandles or footlamberts.
The measurement of either unit is select-
ed by a precalibrated turret attached to
the instrument. The turret can be
removed for the addition of accessory
attachments for special readings.

SPECIFICATIONS FOR PHOTOMETER LX
The Photo-Meter 1, 2 and Lux Meter are precision digital meters for
laboratory, scientific and industrial use, as well as for video and cin-
ematographic applications wherever accurate footcandle, footlambert
or lux measurements are called for. The hand-held Photo-Meters are
used for lighting surveys by architects, designers, or industrial engi-
neers to determine the efficiency of lighting design. For example, they
can quickly compare ambient illumination to video screen brightness
to determine suitability of the visual environment. The switch from
footcandle or footlambert calibration is accomplished in seconds.
Cinema, video, and still photographers use Photo-Meter 2 for light
readings that are more precise than those with conventional light-
meters. Scene lighting of sets can be measured and adjusted for uni-
form illumination. This is particularly important for critical, high
contrast video work. Other applications suited to the pocket-sized
Photometers are stage lighting design, greenhouse surveys, measure-
ment of illuminated signs, lamp manufacturers’ testing, and more.
Photometer LX (PMLX)
Used for lighting surveys by architects,
designers, or industrial engineers to
determine lighting design efficiency.
Quickly compares ambient illumina-
tion to, for example, video screen
brightness to determine suitability of the
visual environment. The switch is accom-
plished in seconds. Scene lighting of sets can
be measured and adjusted for uniform illumi-
nation. Other applications suited to the pocket
Photo-Meter LX are stage lighting design, green
house surveys, measurement of illuminated signs,
lamp manufacturers’ testing, and more.

Rotating Illuminance Receptor (PM-11)
The receptor disc rotates to read footcandles
from any direction. This type of receptor is used
frequently by TV and film camera-men, and
its operating position is preferred by some.
When ordered, PM-11 replaces the standard
turret supplied with photometers. PM-11 has an
alternate position for footlambert readings.
Meter must be calibrated.

Fiber Optic Probe (PM-12)
This flexible probe is approximately 12˝
(30cm) long by
1
⁄8˝ (3mm) diameter. It
reads luminance of video screens, light
diffusers and other self-luminant objects.
It may also read small areas of film trans-
parencies when illuminated from behind.
The meter must be calibrated.
