Digital 2-in-1 52mm Dual Gauge with Alarm | Water Level and Temperature Monitor for 12V 24V Vehicles

This 52mm dual gauge combines water level monitoring and water temperature reading in one compact unit. It works with a programmable 0-190 ohm signal and includes an alarm function to alert you when levels reach critical points. Designed for boats, trucks, buses, and other 12V or 24V vehicles, it gives you two essential readings from a single dashboard display.

Keeping track of your water tank level and engine temperature separately can clutter your dashboard and make monitoring harder. This 2-in-1 gauge solves that by showing both readings on one clear screen. The stainless steel water level sensor and 1/8 NPT temperature sensor work together to give you accurate data at a glance. The built-in alarm adds an extra layer of safety by notifying you when water level is low or temperature rises too high.

The gauge features a 20-second reading delay to avoid reacting to water splashes inside the tank, giving you stable and reliable readings. Its IP66 waterproof rating and reverse polarity protection make it suitable for demanding environments. The programmable input lets you match the gauge to different sensor resistances, including 0-190 ohm, 240-33 ohm, and 240-30 ohm, giving you flexibility for various setups.

Installation is straightforward with the included fastening ring and wiring diagram. The gauge connects to your vehicle's 9-32V power system and works with both 12V and 24V electrical systems. The high-resolution LED display remains readable even under direct sunlight, so you can check your readings without straining.

Key Features and Benefits

- 2-in-1 dual gauge design that shows water level and temperature on one display, reducing dashboard clutter

• Programmable input resistance from 0-190 ohm, 240-33 ohm, and 240-30 ohm, making it compatible with various sensors

• Built-in alarm that alerts you when water level is low or temperature is too high, helping prevent damage

• 20-second reading delay that ignores water splashes for stable and accurate readings

• IP66 waterproof rating and reverse polarity protection for reliable operation in tough conditions

• High-resolution LED screen that stays visible in direct sunlight for easy monitoring

Who Is This For

- Boat and marine owners who need to monitor both freshwater tank levels and engine temperature from one gauge

• Truck and bus drivers who want a clean dashboard setup with dual readings instead of separate gauges

• RV and motor home users who need reliable water level and temperature monitoring for long trips

• Hot rod and custom vehicle builders looking for a compact, programmable gauge that fits a standard 52mm opening

Usage Scenario

Mark runs a small fishing charter boat. Before this dual gauge, he had two separate displays for his freshwater tank and engine temperature, which made his dashboard feel crowded and hard to scan quickly. He installed this 2-in-1 gauge in the standard 52mm opening and programmed it to match his existing sensors. Now he can see both water level and temperature on one screen. The alarm gave him peace of mind when his coolant temperature started rising during a long run, letting him slow down before any damage occurred. The 20-second delay also stopped false alarms from water splashing in the tank, so he only gets alerts when there is a real issue.

Micro Comparison

Some dual gauges require separate sensors that are sold separately or use fixed resistance values that may not match your setup. This gauge includes both a water level sensor and a water temperature sensor in the package, and its programmable input lets you adjust the resistance range to match different sensor types. The built-in alarm and IP66 waterproof rating add extra functionality and durability that many basic dual gauges lack.

The programmable input means this gauge can adapt to your existing sensors instead of forcing you to buy new ones. The alarm gives you real confidence that you will know about problems before they turn into costly repairs.

Questions and Answers

Question: Can this gauge work with my existing water level sensor?

Answer: Yes, the gauge has programmable input resistance that supports 0-190 ohm, 240-33 ohm, and 240-30 ohm signals, so it can match many common sensors.

Question: Does the gauge work with both 12V and 24V systems?

Answer: Yes, it operates on a working voltage range of 9-32V, which covers both 12V and 24V electrical systems.

Question: How long does it take for the reading to update?

Answer: The gauge has a built-in delay of about 20 seconds to avoid reacting to water splashes in the tank, giving you stable readings.

Question: What size hole do I need to cut for installation?

Answer: You need to cut a 52 mm (2-1/16 inch) diameter hole and allow at least 55 mm (2-3/16 inch) clearance behind the panel.

Question: Is the gauge waterproof?

Answer: The gauge has an IP66 waterproof rating, and the water level sensor has an IP67 rating, making both suitable for wet environments.

Question: Does the package include the water level sensor?

Answer: Yes, the package includes one water level sensor and one water temperature sensor with 1/8 NPT thread.

Question: Can I use this gauge for fuel level monitoring?

Answer: Yes, the programmable input supports fuel level sensors that use 0-190 ohm or 240-33 ohm signals, and the display shows percentage for fuel or water level.

Question: How do I set up the alarm function?

Answer: The alarm activates automatically when water level is very low or temperature exceeds safe limits. You can adjust settings through the button menu on the gauge.
