ETI Mini RayTemp Infrared Thermometer – Gun for Grow Rooms

Point-and-Shoot Surface Temperature Readings

The ETI Mini RayTemp Infrared Thermometer gives an instant, non-contact surface temperature reading from leaf canopy, growing media, ducting or light fixtures — point the built-in laser at the target and pull the trigger. It reads from -50°C to +330°C with ±2°C accuracy, covering everything from a chilled reservoir to the outer glass of an HID bulb.

Key Benefits

• Non-contact reading — checks canopy or equipment temperature without touching a hot lamp or a wet leaf
• -50°C to +330°C range — one tool covers reservoirs, media and hot equipment
• ±2°C accuracy — reliable enough to spot a real problem, not just a trend
• Laser sighting — shows exactly where the reading is being taken from
• 12:1 distance-to-spot ratio — stays usable further back from the target as distance increases

A room's air temperature can read fine on a thermostat while the leaf canopy directly under an HID light is running several degrees hotter — heat stress that shows up as curling or scorched leaf tips before anyone notices the cause. Spot-checking canopy, media and equipment temperature directly catches this kind of localised heat build-up that an ambient room thermometer misses entirely.

How to Use

Point the laser at the surface to be measured — top canopy leaves, media surface, ducting or bulb glass — from a distance appropriate to the 12:1 distance-to-spot ratio, and pull the trigger for an instant reading. Check canopy temperature at multiple points across a grow room, particularly directly under HID lighting, and compare against ambient air temperature to spot hot spots early.
