G.A.S Replacement Probe (Pack 24) – 5m Connector Block

Restore accurate readings with a genuine plug-in probe swap

The G.A.S Controller Replacement Probe Pack 24 is a temperature and humidity sensor for compatible G.A.S environmental controllers that use the newer connector block attachment. A controller is only ever as good as the data it reads, so a worn, drifting or damaged probe leaves it regulating fans, humidifiers and heaters from bad figures, causing swings that stall vegetative growth and invite humidity problems in flower. This genuine replacement restores precise readings with a straightforward plug-in swap, and its 5 metre cable reaches canopy height or anywhere in the room you need to measure.

Key Benefits

• Genuine temperature and humidity probe for compatible G.A.S controllers
• 5 metre cable for flexible placement at canopy height across the grow room
• Connector block attachment matched to newer G.A.S controller models
• Restores accurate climate control of fans, humidifiers, heaters and dehumidifiers
• Stable conditions that support root development and nutrient uptake in veg and bloom
• Suits hydroponic, coco and soil indoor growing setups

How to Use

1. Turn off and unplug the G.A.S controller before starting.
2. Remove the back cover to access the probe connection.
3. Locate the connector block attachment inside the unit.
4. Disconnect the old probe from the connector block.
5. Plug the new Pack 24 probe directly into the connector block.
6. Refit and secure the cover.
7. Position the probe at canopy height for representative temperature and humidity readings.

Before ordering, remove the back cover to confirm your controller uses a connector block, as some older models use a push-fit wire connection instead.
