3M Multi-Gas
Detector 740 Series
 The
3M Multi-Gas Detector 740 Series is designed for ease of use, durability, and
low operating costs. It's the ideal companion for workers on industrial
sites or in confined work spaces - scenarios where potentially hazardous levels
of CO, H2S, O2 or combustible gases may be found.
Apart from its power
to detect up to four gases at a time, the 740 series detector features a bright,
readable display, pre calibrated sensor replacement packs and heavy duty
construction. Simply put: it's smart technology that you can count on to
do its job, so you can focus on doing yours.
The 3M 740 detector
offers a quality instrument with a low operating cost, which is good news for
your employees and your business.
Features
-
Unsurpassed
convenience - The 3M 740 detector makes it easy to replace sensors with a unique
Pre-Calibrated 3M Smart Sensor Pack. Why bother with individual sensors
when you can replace all the sensors with one convenient insert in minutes?
-
Safety First - 3M
has equipped the 740 detector with a 95dBA alarm, dual red LED warning lights
and a vibrate mode to get immediate attention in a busy work environment.
-
Maximum Endurance -
The 3M 740 detector features remarkable staying power with long lasting lithium
ion batteries. Now, you can rely on your detector to provide over 18 hours
of run time. What's more, you can easily swap in three 3M recommended AAA
alkaline batteries on the job if needed.
-
Great features and
accessories - All 3M 740 detectors come with standard rechargeable Li-ion
battery, charger adapter, visual, auditory, vibratory alarms, data logger,
rugged alligator clip, infared port, gas test hood and instruction manual
-
Built Tough - Tough
jobs demand tough equipment. The 3M 740 detector is built with a rugged
circuit board design and a heavy rubberized casing that helps deliver superior
durability and protection against dropping, dust, and liquids.
-
Easy Maintenance -
Stay ready with simply the push of a button: over time or with heavy use,
sensors in any gas detector need to be calibrated or replaced. The 3M 740
detector test mode helps ensure your unit is accurately measuring the target
gas. Detector sensors are stingy when it comes to using calibration gas
for testing. With a recommended flow rate of 0.2 LPM, the 3M 740 detector
can help reduce your overall operating costs. 3M recommends the 740
detector be bump tested or sensor tested everyday before use to help ensure
accurate operation.
-
Long Memory - The
740 detector's long memory allows you to maintain more than 1000 hours (6
months) of dataon usage, exposure levels, and other important site conditions.
