Product Details

Sure Electronics Red LED Temperature Display Dual External Sensors

Temperature displays offer the ability of measuring two different environments at the same time in Celsius (°C) or Fahrenheit (°F), making it perfect for monitoring the temperature of your equipment closet, computer case, amplifier, fish tank or for comparing two devices under test.

Three 7-segment red LEDs offer great visibility and a wide viewing angle. Additionally, this display features auto-brightness for reduced power consumption in darker settings and offers the ability to change the display from Celsius to Fahrenheit with a wave of a hand. The small display housing footprint opens up application possibilities and since it can run on 12 VDC (8.5 to 26 VDC working voltage), this display is right at home in your car or truck.

Included with this display are two waterproof NTC thermal probes on 119" long cables that offer durability and precision incorporating the use of UL and CE-certified cables for low voltage drop. 8" power cable included.

Specifications: • Power requirement: 8.5 to 26 VDC • Current consumption: 36 mA (@ 12 VDC) • Temperature range: -24°C (-11°F) to 125°C (257°F) • Display resolution: 0.1° (@ -9.9°C/°F to 99.9°C/F), 1° (@ 100°F and above) • Accuracy: ± 1.0°C • Dimensions: 3.11" (79 mm) W x 1.65" (42 mm) H x 0.98" (25 mm) D.

Sure Electronics Red LED Temperature Display Dual External Sensors
Sure Electronics Red LED Temperature Display Dual External Sensors is rated 4.0 out of 5 by 2.
Rated 3 out of 5 by from Disappointed so farMaybe I'm not getting it, but that could be because there were no instructions. Seems accurate - is one good plus. But, even though it has .1 F display resolution, it never changes by just .1 or .2 or even .3 degrees. Also, only one temp probe displays at a time and I can't figure out how to change (one is used for internal temp and the other for external temp)! Additionally, the display changes from Celsius to Fahrenheit on its own! From the product description, it says you can wave your hand to change the display. I can't get that feature to work. So, unless I find some manual or instructions somewhere online, or find out this is a defected unit, I'll have to rate this just average at best. I'll update if possible later.

Rated 5 out of 5 by from Sweet....I use two of these in a semi truck. One probe for outside air temp one for inside. One unit located on the dash and one in the bunk area. They are a fraction of the cost compared to units that are made for trucks. I have them wired to remain on all the time... with no issues.

Sure Electronics Red LED Temperature Display Dual External Sensors

I just received one and it does not appear to work at all with 12 V applied from a battery and with the sensor plugged in to either of the input jacks.  Is there some trick to this?
