Gas-Pro TK Portable Multigas Detector

Hydrocarbons stored in inerted environments create a particular flammable gas detection challenge, whether during transport at sea or storage on shore. Gas-Pro TK dual-range portable monitor is designed for use in this specialist environment where standard gas detectors just won’t work whether tank purging or gas freeing. More

Tank check functionality summary

Tank specialist Designed to perform in the challenging inerted tank environments
Dual IR sensor Detects the spectrum of possible flammable gas concentrations from high %vol to low %LEL.
Auto-ranges, switching between %LEL and %vol as gas concentration demands.
Notifies you of auto-ranging as it happens
Monitors oxygen Know when it’s safe to load fuel
Know when it’s safe for operators to enter
High H2S sensor option Understand possible risks if gases vent during purging helps inform you of potential risk from pyrophores
Alarms disabled in tank mode High gas levels are to be expected, so alarms can be misleading and annoying
Automatic flow plate recognition Integrated pump turns on as soon as the flow plate is applied
Tank samples can be drawn from up to 98.4ft


Mode indication Clearly indicated when in Tank Check mode, avoiding potential confusion
Confirmed alarm status In Tank Check mode, alarms are disabled. You must acknowledge this before you can proceed

Personal monitor functional summary

Personal gas detector Gas-Pro TK has full Gas-Pro functionality, so can double up as a personal detector, as required Full range of alarms are enabled: audible (>95dB); visual (red and blue flashing LED); tactile (vibrating)
Confined space pre-entry check function Assists you through the pre-entry check process

Personal protection monitor

Gas-Pro TK is an extension of the Crowcon Gas-Pro range. Therefore, in addition to its superb Tank Check capabilities, it also offers the full personal gas detection and confined space pre-entry check functionalities provided by other Gas-Pro units. Gas-Pro TK units are black, so you can easily tell them apart from other Gas-Pro in your detector fleet.

As an additional, important safety feature, before it can be returned to Tank Check mode, Gas-Pro TK demands confirmation that the user understands that by doing so, they have disabled the alarms.
