iTX Multi Gas Monitor

Capable of Monitoring 1-6 Gases

The iTX Multi-Gas Monitor is the industry’s most versatile portable gas detection instrument. Designed to grow with you as your monitoring needs change, the iTX can go from being a single gas unit to a six-gas monitor, or anything in between, with just a few simple user configurations and sensor changes. Featuring advanced “smart” sensor technology, the iTX is capable of recognising and configuring a wide assortment of field replaceable, interchangeable sensors. 
Enhanced benefits include a 50 ppm resolution for hydrocarbons, LEL and methane sensor over range protection, and a zero-bias ammonia sensor for increased stability. Providing simplified, single-button operation and calibration functions, the iTX’s special Quick-Cal feature quickly calibrates up to four sensors at once, saving time and calibration gas costs.
The iTX provides superior, user configurable datalogging and hygiene functions which allow the monitor to store up to 300 hours of survey data at one minute intervals. The unit also includes STEL and TWA readings and alarms as well as iButton® technology, which allows the operator to input user data and site information.
The iTX also features a backlit LCD that simultaneously displays all gases monitored, ultra-bright LED visual alarms and a powerful 90 dB audible alarm, all encased in a compact, rugged stainless steel housing to provide maximum durability and RFI protection.
The iTX boasts superior security and safety features including configurable user access codes to protect calibration and alarm settings, and a time delay power button to prevent accidental turnoff. The unit is also DS2 compatible to utilise the additional benefits of the Docking Station™.
