The Fluke 50 Series II digital thermocouple thermometer is used for applications requiring a broad range of temperatures, including furnaces, kilns, freezers, and other industrial applications. This thermometer measures temperatures in Celsius, Fahrenheit, or Kelvin via a Type K, Type J, Type T, Type E, Type N, Type R, or Type S thermocouple probe. It comes with one or two Type K bead thermocouple probes with 40" cables that measure from -40 to +260 degrees C (-40 to +500 degrees F). It can store up to 500 points of data for analysis and monitoring, and it has an infrared communication port for exporting data to a computer for analysis. This thermometer provides the relative time of minimum, maximum, and average temperature measurements for monitoring. It has an offset function that allows the operator to compensate for thermocouple errors and increase accuracy. The thermometer body protects against splashing water and dust, and it comes in a holster that absorbs impact to help protect against damage if dropped. The thermometer enters sleep mode after 20 minutes of inactivity to help preserve battery life. It conforms to National Institute of Standards and Technology (NIST) standards for compliance with regulations. The European Conformity (CE) marking indicates compliance with applicable European Union (EU) directives, and CSA mark indicates compliance with applicable Canadian Standards Association directives. This thermometer is suitable for measuring the temperature of equipment, systems, and processes in industrial and manufacturing environments.

Type K temperature range -200 to +1372 degrees C (-328 to +2501 degrees F)

Type T temperature range -250 to +400 degrees C (-418 to +752 degrees F)
Type E temperature range -150 to +1000 degrees C (-238 to +1832 degrees F)
Type N temperature range -200 to +1300 degrees C (-328 to +2372 degrees F)
Type R and Type S temperature range 0 to 1767 degrees C (32 to 3212 degrees F)
Temperature accuracy above -100 degrees C Type K, J, T, E, and N: + or - 0.05% + 0.3 degrees C; Type R and S: + or - 0.05% + 0.4 degrees C
Temperature accuracy below -100 degrees C Type K, J, E, and N: + or - 0.20% + 0.3 degrees C; Type T: + or - 0.50% + 0.3 degrees C
Display resolution 0.1 degrees C / degrees F / K < 1000 degrees; 1.0 degrees C / degrees F / K > or = 1000 degrees
Applicable standards NIST-175
Power Supply (3) AA Batteries
Weight 400g
Dimensions 173 x 86 x 38mm (H x W x D)

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Digital thermocouple thermometers measure the temperature of air, liquids, or surfaces. They may measure temperature in Celsius, Fahrenheit, or both. Thermocouple thermometers are composed of two conductors of different metals, usually alloys of the same metal, which touch at the sensor end of the thermometer. The difference in conductivity between the two metal pieces produces a voltage flow between the sensor end and the open end of each conductor, which can be used to determine the temperature. Different alloys are used for different temperature ranges. Thermocouple thermometers are used in applications that require a large temperature range and do not require a high degree of accuracy. These thermometers are used in kilns, turbine exhaust systems, and furnaces.

Fluke Corporation manufactures electrical testing tools and software for industrial and commercial applications. The company, founded in 1948, is headquartered in Everett, WA.

La Crosse Technologies V10-TH

The La Crosse V10-TH Wireless Weather Station (Model No. C84343) is absolutely wonderful. The setup was easy with the Quick Setup Guide provided with the unit. The packaging contains additional support information with the website and phone number if there are questions. I especially liked the daily high low readings and the color on the unit! Tech Instrumentation provided great communication as to the availability of the product and shipping details. If fact, it arrived one day prior to the estimated delivery date. I would absolutely recommend this product and Tech Instrumentation for anyone looking for an indoor/outdoor weather station!


I needed a replacement as my original sensor no longer worked. This one works fine.

Excellent Customer Service!

I can't way enough about the customer service at Tech Instrumentation. I was looking for a hard to find specialty part, which the manufacturer told me would need to be custom made. After calling and speaking with a representative at Tech Instrumentation, the part was located and order was filled, right over the phone. Delivery was prompt, and instrument is working great. Highly recommended company for lab supplies!

Worked great

Put batteries in and worked great
