2. T4x Features TWA resume function Unique this innovative feature ensures toxic gas exposure is calculated accurately over an entire shift, even if switched off for a break or during travel to another site. Battery life T4x: 35+ hours battery (double the battery life of our original T4) allows multiple or longer shifts to be worked between recharging. Backlit display Large, clear display with backlight and option to flip the screen 180° for easy viewing whilst worn. Rugged design With a thick anti-shock rubber casing and drop tested to 4 metres on concrete, provides dependable operation under the most demanding use. Water & dust resistant to IP65 & IP67 Provides protection in the harshest environments. Dedicated sensors One sensor for every gas ensures effective, fast and reliable detection. Positive safety indicator A simple ‘traffic light’ status indicator which, at a glance, provides visual assurance of operational and compliance status to both users and supervisors. Green light - Working safely Red light - Attention required Intrinsically safe T4x: ATEX Type 1 (Zone 0) approved and UL Class 1 Division 1 allows for uninterrupted working in the most demanding environments. Multiple alarms Audible 95dB alarm, bright red/blue LED’s and vibrating alerts provide effective warning to gas hazards. Easy operation Large single button and intuitive menu system minimise training and allow easy operation whilst wearing gloves. T4x helps ensure compliance across site by eliminating the need to ensure each device is calibrated for the relevant flammable gas as it accurately detects more than 15 flammable gases, in any mix, at once, while being Type 1. Being poison resistant and with battery life doubled, operators are more likely to never be without a device. T4x reduces the 5 year total cost of ownership by over 25% and saves 12g of lead per detector which makes it easier to recycle at the end of its life, and better for the planet.
