Uploaded by Melati

TSI’s Gas Monitor Model GM460 is a rugged handheld instrument designed for simultaneous detection of up to six gases in harsh environments. It supports four standard confined-space gases (combustibles, O2, CO, H2S) plus two smart sensor slots compatible with PID, IR, or super toxic sensors. The device features bright multi-angle LED alarms, vibration and loud audible alerts, internal sample pump, IP-67 dust-and-water resistance, and flexible power options (Li-ion or alkaline).

Gas Monitor Model GM460 TSI’s Gas Monitor Model GM460 is a powerful hand-held instrument capable of simultaneously monitoring up to 6 gases. In addition to the standard 4 confined space gases which include combustibles, O2, CO, & H2S, the GM460 has two additional smart channels that accept PID, IR or super toxic sensors. The GM460 has a rugged design, built for the harshest environments. It is equipped with a removable impact-resistant rubber boot and a dust-and water-resistant enclosure with an IP-67 rating. With 5 bright LED lights on 3 sides of the instrument, alarms are easily seen from a variety of perspectives. With vibration and loud audible alarm, GM460 will easily alert users when needed. Features and Benefits ▪ Monitor up to 6 gases ▪ 2 smart sensor slots auto recognize PID, IR, and super toxic sensors ▪ 6 operating modes: normal, leak check, benzene select mode, inert, snap log and bar hole ▪ Library of over 600 VOCs ▪ PPM Leak Check mode ▪ Man-down and panic alarms ▪ Auto display rotation ▪ LED light source ▪ Internal sample pump ▪ Glove friendly, glow-in-the-dark buttons ▪ Light weight, small, rugged IP-67 design ▪ Interchangeable battery packs Li-ion / alkaline ▪ Operates up to 14 hours on Li-ion battery pack, fully recharges in 3 hours ▪ Field replaceable sensors, batteries and filters Applications ▪ Remediation sites ▪ Perimeter monitoring ▪ Leak detection ▪ Landfill monitoring ▪ Hazmat response teams ▪ Arson investigation ▪ Confined space entry ▪ Wing tank entry Equipped with a strong internal sample pump, a man-down alarm, a panic alarm, an LED flashlight, and large auto rotating LCD display, the GM460 can operate as a single gas PID unit or a multifunctional tool utilizing all 6 channels. The GM460 with a PID sensor will come equipped with a library of over 600 VOC gases to choose from as standard. Choosing from the library is easy, with a personalized favorites list of 30 commonly used VOC’s as well as a list of 8 of the most recently used VOC’s. A benzene-specific version is available using a pre-filter tube for detecting low levels of benzene. Measure PM2.5, PM10, and gas in one enclosure The GM460 easily mounts into the DustTrak™ Environmental Monitor. Measure both mass and gas in any outdoor application.
