Icstation Digital Car Thermometer - Automotive Temperature Gauge Sensor

RS: Great value - easy to read. Probably within a degree or 2 accurate. Need to add a cheap DC power adapter to it. I use it to monitor the input and output temperature of my central air conditioner evaporator coil to try to predict when it will need recharging with refrigerant, since it has a small leak. (There should be about a 20 def F temperature differential).

MoparMan91: Primary problem, live view of potentiometer value based on ntc temp curve.

I have a simulator system with 2 controllers, one allows me to check inputs, simulated by potentiometers, the other allows me to simulate use case scenarios of a AC, after processing through an ecu.

The ecu interprets the potentiometer settings and reacts how it would if actually installed. However I can not simulate the response, and view the inputs at the same time, thus my interest in this product.

With a potentiometer simulating the temperature of ntc sensor, I initially tried to reference a 10kohm @25c chart to find my temperature, however the values were inaccurate.

Using this product it returns a code reading LLL. I assume its out of range.

however out the box it work well, and is accurate. If you are inclined you can use most types of 10kohm@25C NTC probes, and extend the probe cables as needed, I believe you could use a Molex 2181120204 pigtail, and butt connectors to customize your device, as it should connect to any of the 3 inputs where you could change wire lengths as needed, I believe adding a substantial amount of length could however introduce some error in...

beckalizbeckaliz: I am pleased with this product and I think I could make good use of it. I have compared the measurements it takes against a precision temperature monitor that I have and the results are within +/- 0.5 degrees Fahrenheit (possibly better). (There is a photo showing how I connected the probes of the other temperature monitor for the comparison.) I would buy another if I needed a second one.

I tested it from 4VDC to 28VDC and varied the power supply output rapidly by hand. It handled it without issue. I did not do high speed power input testing, though (but really that's a bit excessive for a product like this anyway).

There are a few things I would mention to buyers of this device:
1. The temperature probes have a fairly high thermal mass (they are large). This is not necessarily bad, but it means that they will not react very quickly to temperature changes. For an automotive application I don't think this is a bad thing - it is just an observation. This is why the product description mentions it working best in water (as in an aquarium, etc.).
2. If you run the device at its maximum voltage (28V), it heats up after a few minutes. It draws 0.250W at 28V but only...

JohnG: So I know that the IS Icstation Digital Thermometer was meant for use with fish aquariums but as usual I have found other uses for it.

First of all I was surprised at the accuracy of the unit and the tracking of the two probes. They were within .6 degrees (F) of each other. Again, very surprising for a device in this price range. The unit is well built and simple to set up and operate as there are no user controls or calibration procedures. The wide input voltage range (4-28 VDC) lends its self to well various power supply options. I used an old USB “Wall wart” that I had lying around. Although I have not yet used the complete temperature range of -58F~257F it is nice to know that such a wide spread is available.

The winter season is beginning here and this past week I have seen temperatures down to 18 degrees (F). I figured that it was time to prepare my gas fired furnace for the long cold season.

First of all if you are not qualified and trained to do any of the procedures I talk about here, DO NOT DO IT!

I used the digital thermometer to check the temperature differential between the return air and output air of my furnace. After all, the...
