Redarc Dual Temperature 52mm gauge with Optional Temperature Display, 2-year warranty. The REDARC 52mm dual temperature gauge is ideal for monitoring your engines oil and water (coolant) temperature. The G52-TTT gauge is supplied with two REDARC 1/4 NPT thread temperature senders that measure from 60 to 150°C.
Oil subjected to excessive temperatures can lose its lubrication properties that keep metal parts from touching. If the oil temperature rises above the desired limit, you can reduce the load placed on the engine or transmission to reduce the temperature and prevent engine failure. Similarly, monitoring the water (coolant) temperature of your engine ensures that it does not overheat, resulting in major engine damage.
The G52-TTT gauge also supports one of four optional temperature sensors. You will need to purchase one of the following REDARC temperature sensors to equip the gauge with this function:
GS-UT-80: An NTC temperature sensor in a plastic housing for measuring cabin, fridge or outside temperature. The range is -20~+80°C. This sensor is supplied with a 6-metre extension cable.
GS-UT-120: An NTC temperature sensor in a metal copper housing with 6mm diameter mounting hole. The range is -20~+120°C. This sensor is supplied with a 6-metre extension cable.
GS-OWT1-4: Water or Oil temperature sender. 1/4 NPT threaded. Designed to measure from -20~ +170°C. Supplied with the 3-metre extension cable.
GS-OWT1-8: Water or Oil temperature sender. 1/8 NPT threaded. Designed to measure from -20~ +170°C. Supplied with a 3-metre extension cable.
The G52-TTT gauge diameter requires a 52mm hole for mounting. REDARC offer a range of mounting solutions including a 2” black plastic mounting cup (GH-CUP) and one (GH-MP1), two (GH-MP2) and three (GH-MP3) hole gauge mounting panels. Radio inserts are also available that suit the Toyota Hilux (GH-RI05).
The REDARC 24 to the 12-volt adaptor (GA-2412V) can be used to connect this gauge to a vehicle with a 24-volt ignition and lighting supply, however, only a 12-volt battery can be monitored.
Enhanced Lighting Controller
REDARC recommends the purchase of an Enhanced Lighting Controller (GA-ELC) with this gauge. The GA-ELC is designed to enhance the lighting of your REDARC gauges as only one required for a set. It is to be used when you do not have a dimming circuit to connect your gauge to or the dimming circuit in your vehicle does not dim the REDARC gauge to your liking.
The GA-ELC also allows you to program nighttime brightness and colour of your REDARC gauges, including dimming if connected to a dash dimmer. Once programmed your gauges will change colour when turning on your park lights and back to a daylight colour when you turn them off. The GA-ELC is also 24 volt capable.
Satin Chrome Bezel
13 Selectable Backlight Colours
Multiple programmable alert levels with amber or red backlight and audible beep
Display illuminates when park lights are turned on so you can check battery voltages and discharge or charge current without turning on the ignition.
If fitting more than one REDARC gauge, a communications link can be connected between the gauges to change the backlight colour all at once.
