Water Temp Gauge(Celsius)

This is a reliable and accurate gauge.Just be sure to note that it reads in metric Celsius/Centigrade.The warning light comes on at 100° C.Hook up was easy. The temp sender is 1/4 NPT. If using Teflon tape be sure to NOT wrap the end of the sensor.Be careful when installing as the electrical connection stud on the sensor is easily damaged. This is not a failing of the product just inherent in the design. Be sure to use a deep enough socket when installing so there is no pressure on that stud when installing.The included cable is only a few inches long so you will need extra wire for the sensor and/or electrical connection.There are three wires: black (-) & red (+) for power and a green sensor wire

Good product but corrosion in marine use

Bought this for a water cooling project. I needed something cheap and easy to read. I accidently ordered Celsius when I needed Fahrenheit. No biggie I need to learn the metric system anyway.

Wires to connect VERY SHORT...must spice in more wire to reach sender from gauge.Sender for block connection very small must buy some type of adapter.I gave up and used a mechanical gauge.

I recently purchased this HOTSYSTEM water temperature gauge for my car, and despite a small incident that occurred during shipping concerning an incorrect gauge, I cannot be more satisfied with my purchase of this water gauge. Not only are HOTSYSTEM gauges very high quality performance parts, but the customer service on their end is absolutely phenomenal. The people there at HOTSYSTEM worked with me as quickly as possible to replace and reship the guage that I originally ordered. I highly recommend this gauge and this company! I am truly grateful and impressed!

This gauges will precisely monitor the temp within your coolant that is within a range of 40to 120 celsius. This series is fully electronic with a blue digital LED readout, which allows for easy viewing at all angles during all lighting conditions. Each gauge includes an temperature sensor with all necessary mounting and installation hardware. that's not true in order to have this device installed you have to buy a separate part which is called sensor attachment which is in fine print this is a real headache to have purchased something then you find out you don't have everything you need :(

It's in Celsius not Fahrenheit, so if you dont know the conversion might suggest looking for a Fahrenheit guage.

Works as it should looks really good love it wiring was easy as I have never done it before and was super easy. Bought 4 of them all different gauges obviously 🙄 and they are all great.
