Universal Application. Singular Performance. You’ll find
Honeywell Sensing and Control (S&C) hour meters where quality,
performance and rugged construction are needed. So track and
record elapsed time more effectively and efficiently, whether in
hours or tenths of hours. Log running time of your equipment,
designed to assure proper maintenance of expensive machines
or systems, or track warranty programs. Often eliminate the
guesswork with elapsed hours for better machine resale value, or
logging actual time on your rental products.
Hour meters differ by power, display, shape and data. And
while there are many factors to consider — from panel profile,
to analog or LCD, shock and vibration resistance to noiseless
performance — Honeywell S&C is your one-stop shop. No matter
the terminal specification, the shape or configuration, we’re up-to-
the-minute on hour meter technology and applications.
FEATURES
AC/DC HOUR METERS
LM Series.
Features: Accuracy: ±200 ppm/hour
• Backlight and large 7 mm display •
Digital, microcontrol unit LCD • Durable
design of mounting assembly • IP67
environmental sealing • Customizable
Benets: LM Series microcontroller
unit LCD hour meters are sealed digital
instruments to monitor and record elapsed
running time. The large 7 mm display
eases readability and offers backlight
options and a running indicator.
The hour meter also features a long reset
time to offer customers the protection
against malfunction of reset. Shock and
vibration resistance allow for use in a wide
variety of tough transportation applications
including agricultural vehicles, blowers,
engines, heavy-duty construction vehicles,
heavy-duty trucks, mterial-handling equip-
ment, and mowers.

AC HOUR METERS
20000 Series.
Features: Polycarbonate, shock resistant,
tamper-proof case • Totally sealed •
Single phase, synchronous, permanently
lubricated motor • Custom logo dials,
screw terminal, wire lead or 1/4 in blade
terminals, special wire lengths
Benets: From testing purposes to leasing
applications, maintenance and warranty
programs, this often accurate, reliable
hour meter passes 100% function and
timing accuracy tests before shipping. All
parts are in process inspected and benefit
from an uncommon design — integrating
the motor and frame into one substructure.
28100 Series.
Features: Unlike conventional hour
meters, this hour meter operates over a
full range of voltages and frequencies.
Working accurately over a voltage range
of 90 Vac to 264 Vac and frequencies
of either 50 Hz or 60 Hz, it fits a wide
range of applications, anywhere in the
world. It offers reduced parts count and
inventories. With fewer purchase orders
and reduced service parts, the meter often
eliminates production line errors.
Benets: Records time 0 to 99,999.9
hours • Accuracy ±0.02 % • UL
recognized • CSA (UL) • CE mark
• Totally sealed from dirt and moisture
• Termination - 1/4 in spade • Options
include custom lens and terminal
orientation (up, down, straight)
301 Series.
Features: Offering enhanced accuracy
and quiet operation in an economical
design. The display reads to 1/100 of an
hour for greater resolution. Available in
standard case configurations that can
interchange with virtually all meters on the
market.
Benets: Often ideal for multiple
applications: medical, office equipment,
electric panels, tanning beds, fans, and
furnaces
