The HHLM112SD has a large
backlit display for easy viewing of
light levels. Comes complete with
light probe with protective cover and
can measure a wide range of either
LUX or footcandles. Applications
include indoor light and work area
lighting monitoring and verification
useful for facilities engineers,
building maintenance personnel and
anyone who wants to measure
illuminance. Ideal for Industrial and
commercial photography and
videography applications. Because
it is microprocessor-based, the
HHLM112SD can make full use of
the portability, reliability and large
storage capacities that SD memory
cards offer. Measurements can be
made automatically at any sampling
rate between one second and one hour. After the instrument timestamps
and stores the
measurements on an SD card
plugged into it, the user can remove
the card and plug it into a laptop or
desktop computer either directly or
via a USB card reader. The logged
data is stored on the card as files
that can be opened by Microsoft’s
Excel application. Unit accepts SD
memory cards as large as 16 GB.
Temperature measurements are
made using a Type K or J
thermocouple. The HHLM112SD is
powered by 6 “AA” alkaline batteries
or an optional AC adaptor.
