Product Details

Red 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 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 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 38" long cable that offers durability and precision, 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" (79 mm) W x 1.65" (42 mm) H x 0.98" (25 mm) D.

Red LED Temperature Display Internal & External Sensor
Red LED Temperature Display Internal & External Sensor is rated 4.0 out of 5 by 2.
Rated 3 out of 5 by from Unexpected surprisesI was surprised to find the power input wires had no plug - I guess I was expecting an automobile cigarette lighter (male) plug. I had to buy one and solder it on (with some extra wire, since their wire leads were short).There was NO instruction sheet included! I went on line and found extremely brief "user guide" comments. A clue was that the DIP switches controlled C/F degrees. But nothing said how to set them. It turns out there are 4 switches (a possible 16 combinations) and you have to experiment. After some anger I finally discovered (by trial & error) that setting #1 & #4 in the on position (#2, 3 off) results in degree F display AND alternates the display between CH1 & CH2 - what I wanted. I have no idea what other switch combinations do, and never will. This satisfied my needs, and it works great (now)!

Rated 5 out of 5 by from Great for monitoring equipment baysI bought this to monitor the temperature in my stereo case. It seemed to be too hot from the back, and I don't want to have to replace my tuner or CD recorder. I responds quickly to temp changes, and is big enough to see from across the room without being garish. It auto-dims in the dark, which my wife really likes.

Can the sensor cable be extended?

Is it possible to extend or purchase a longer sensor cable?
Asked by: Yattr
Yes the cable can be extended although we do not sell longer cables than they come with. you will have to splice a small 2 conductor wire in between the plug and sensor.

Is the face (display side) waterproof?

Asked by: Chinpokumon
The sensors are water-resistant, but to my knowledge, the display itself is not.

what is length of the probe cable?

Can you manually shut off the wave C/F change feature?
Asked by: Peterwolfs
The probe is on a 38" cable, and yes, the "wave" feature for switching between C and F readout can be disabled at your discretion.
