## Description

Proster Digital Thermocouple Temperature Thermometer Dual Channel - with Two K-Type Thermocouple Probe, Backlight LCD Thermometer for K J T E R S N Type: desertcart.com: Industrial & Scientific

## Features

- Support K/J/T/E/R/S/N Type Thermocouples Measurement: Packed with two K-Type thermocouples, this Proster Digital Thermocouple can direct measure the temperature of tested object
- Considerable Measuring Range: Can be used to measure the temperature of liquid / vapors and surface temperature of a solid object.Also suitable to be used both in the high temperature fields of blast furnance and cookery and the low temperature measuring for liquefied hydrogen and liquefied nitrogen etc
- High Accuracy: K-type Thermocouple Measuring range: -50~300℃ ; Accuracy: 1.5%; Resolution: 0.1℃/℉＜1000°,1.0℃/℉≥1000°
- Functional Design: Data Hold Function;MAX/ MIN/ AVG Value Measurement;Auto Power Off; Double display with LCD Backlight shows T1/T2 and combination of T1 and T2
- Wide Applications: Fish tank, pool, furnaces, ceramic, pottery, molten metal etc Test Tips: Five seconds is generally sufficient in a stable ambient temperature environment. For moving liquids, however, a longer time is required—wait until the liquid stabilizes for an accurate reading
- 【Compatible with 7 Thermocouple Types】 Beyond K-type, this thermometer supports J, T, E, N, R, and S thermocouples (probes sold separately). Each type offers different ranges: J-type: -210~1200°C | T-type: -250~400°C | E-type: -150~1000°C N-type: -200~1300°C | R/S-type: 0~1767°C
- 【Dual Channel with T1-T2 Differential Measurement】 Monitor two separate temperature sources simultaneously on one backlit LCD screen. The T1-T2 (ΔT) function automatically calculates the temperature difference between your two probes – perfect for inlet/outlet HVAC diagnostics, radiator temp drop, heat exchanger efficiency testing, or supply/return temperature comparisons

## Questions & Answers

**Q: Can the probe's plastic insulation be stripped back an additional 2". Would like to place end of probe between to aluminum plates**
A: Yes they can.

**Q: How long are the probes?**
A: The probe leads are just over 40” k type thermistors. For the money this is a good tool to have. 
For any  Critical temperature measurements I use the copper brand

**Q: Does this thermometer have a user calibration option? Does it have cold junction compensation?**
A: Not that I know of. A digital thermometer, that, depending on the probe, can measure extreme heat and cold.

**Q: Would this make a good field thermometer - subject to wet conditions?**
A: Not sure about the unit itself the probes can be put in water.
