Product Details

Sure Electronics Blue LED Temperature Display Internal & External Sensor

Temperature displays offer the ability of measuring two different environments (one local, one remote) 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, pool or for comparing your indoor temperature versus the temperature outdoors.

Three 7-segment bright blue 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 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 is a waterproof NTC thermal probe on a 119" long cable. The cable is UL and CE-certified for low voltage drop. 8" power cable included.

Specifications: • Power requirement: 8.5 to 26 VDC • Current consumption: 36 mA (@ 12 VDC) • Temperature range: Internal sensor: 0° C (32° F) to 60°C (140°F), External probe: -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: Internal sensor: ±2.0°C, External probe: ±1.0°C • Dimensions: 3.11" W x 1.65" H x 0.98" D (79 x 42 x 25 mm).

Rated 2 out of 5 by from External sensor cord failuresI like the way these work in general. I have however had problems with the sensors cords all of a sudden starting to read very high temperatures. I was using to measure temp of water in a hot tub, generally around 102 degrees. Sensor starter reading 203 and jumping around plus or minus 10 degrees. Put cord from another unit I had and that's working ok for now.

Rated 4 out of 5 by from Minor issue, but overall good itemI bought both a red and blue display version.  Nice items for the price, but one needs to adjust the dip switches in order to get the units to function as advertised.  The problem is-they don't come with a chart indicating what the switch settings should be to get the desired function.  It only took a few minutes to figure out, but still a bit frustrating.

Rated 5 out of 5 by from Good ProductThis unit came as described but with an added bonus. It had a long probe which made me install much more flexible.
