The 3M 740 Series multi gas detector has been discontinued. Please contact AFC International for other multi gas detectors to fit your applications.

The 3M Multi Gas Detector 740 Series is designed for ease of use, durability, convenience and low operating cost. 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 95 dBA 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, infrared 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. The 3M 740 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 every day before use to help ensure accurate operation.
• Long Memory - The 740 detector's long memory allows you to maintain more than 1000 hours (six months) of data on usage, exposure levels, and other important site conditions.
