Product Details

AccuTech SMi Water Temperature Gauge in Modular Panel - 100 - 280 


'Stepper Motor' Racing Gauges
The next generation in instrumentation

Stepper motor gauges use a small electronic motor that only turns a tiny fraction of a rotation to drive the pointer. It is electronically controlled and is much more precise than the traditional mechanical instruments whose accuracy can be affected by many factors. Many professional race teams -NASCAR, etc. " are switching to this style of gauge for the improved accuracy(see the in-car cameras). Approved for use by IMCA.

Built-in Warning Lights " Ultra Bright 2 Stage LED
2 set points are easily adjusted to your needs (critical oil pressure has 3 set points). For example set water temp for just above normal running temp (if you run 215F set it at 230F). Above that the LED comes on to let you know the motor is starting to get warm. Set the second one at the max temp your engine can tolerate (say 250?). At this point the LED flashes to attract your attention, possibly saving motor damage.

Since oil pressure is so critical it has 3 set points.
You can set the first just below normal running pressure (say normal is 60 psi " set it at 50 psi " no damage there). At this point the LED comes on. Set the second at 35 psi. The LED flashes " you need to know here, possible damage. Set the third at 20 psi. Engine damage is likely here. At this third set point the LED continues to flashPLUS the gauge backlight starts to flash.It s hard to miss this " day or night. It allows you to get the engine shut down before it blows up, saving you $$.


  • Gauges are2-5/8" and have a molded polycarbonate / ABS case (virtually unbreakable)
  • Anelectronic sensor(incl.) is installed on the motor to drive the gauge -no oil or fuel in the driver s compartment for safety.
  • Thru-the-dial LED backlightsand an illuminated pointer make these easy to read at any speed
  • ?Presentation? at turn-on- Gauges go through a self test. Pointers swing full scale and all LEDs come on
  • Quick & simple to install- Connect power to one gauge and daisy chain the others to it (wiring included). Connect the sensor wire and you re done
  • Can be used with 12 & 16 Volt negative ground systems


Modular Composite Panel
Build Your Own Panel -the way you want it

Here's a different way that gives you flexibility in laying out your gauges. These individual 'modular' panels can be arranged any way you like and are easily connected by just plugging in the wiring included. The panels are lightweight molded ABS with a carbon fiber pattern and really look great. Build your custom panel with any combination of gauges, as many as you need, with or without a tach.
