Digital Temperature Gauge 37mm with 40 Inch Capillary Tube – Universal 12/24V

Description

There’s nothing worse than cooking an engine or burning up a hydraulic pump because you didn’t know things were running hot. This digital temperature gauge takes the guesswork out of monitoring your equipment’s vital signs, giving you exact temperature readings instead of hoping that old needle gauge is telling the truth. Whether you’re watching engine temps on an older tractor or keeping tabs on hydraulic oil heat during heavy work, you’ll know exactly what’s happening before problems turn expensive.

What You’re Getting

• Digital display shows precise temperatures from -40°C to 125°C (-40°F to 257°F) – no guessing with analog needles
• 40-inch capillary tube reaches anywhere you need to monitor, from engine blocks to hydraulic reservoirs
• Works on both 12V and 24V systems automatically – one gauge fits everything in your fleet
• Bright LED display stays readable in blazing sun or dark cab conditions when you need it most
• Compact 37mm face fits tight dash spaces with standard 29mm mounting hole

Built for Real Farm Work

This gauge monitors any temperature-critical spot on your equipment. Mount it to watch coolant temps on that ’80s tractor with the questionable cooling system, keep an eye on hydraulic oil during hay season when your loader’s working overtime, or monitor transmission temps on your biggest rig during heavy tillage. The long capillary tube lets you place the sensor exactly where the heat matters while keeping the display where you can see it.

Made to Last

Digital gauges used to be fragile, but this one’s built for tractor life. The electronics are sealed against dust and moisture that get into every cab, and the flexible capillary tube is armored to resist damage from engine heat and sharp edges. Unlike analog gauges that drift over time, this stays accurate year after year, and the LED display won’t fade or fog like old gauge faces.

Installation Notes

The 29mm mounting hole is about 1-1/8 inch – a common gauge size that often matches existing holes. The 40-inch capillary gives you plenty of reach to route from dash to engine or hydraulic tank. For coolant monitoring, thread the sensor into an existing boss or the dipstick hole. For hydraulics, the dipstick tube usually works perfectly. You can switch between Celsius and Fahrenheit depending on your preference. Having accurate temps helps you catch problems early, like a radiator starting to plug or hydraulic oil getting too hot from a failing pump.
