R-Tek Digital Probe Thermometers

A. Product Overview

R-Tek Digital Probe Thermometers provide direct contact temperature measurement through a probe inserted into or placed against the material being tested. The series is suitable for liquids, food products, refrigerated items and a variety of general temperature measurement applications.

RT-600Pro Digital Folding Thermometer
The RT-600Pro features a folding 304 stainless steel probe with a measurement range of -50°C to 300°C and 0.1°C resolution. It provides a backlit display, fast response, temperature hold, MAX and MIN memory, Celsius and Fahrenheit selection and automatic power operation through the folding probe.

RT-850N Digital Probe Thermometer
The RT-850N measures from -50°C to 300°C with 0.1° resolution. It features a waterproof design, bright backlit LCD, magnetic mounting, temperature hold, low battery indication and automatic power off.

RT-500 Digital Probe Thermometer
The RT-500 provides a measurement range of -50°C to 300°C with 0.1°C resolution. Important functions include HI and LO alarm settings, MAX and MIN temperature memory, data hold, Celsius and Fahrenheit selection and stainless steel probe covering.

RT-604N Digital Probe Thermometer
The RT-604N comes with two probe options. A rotating probe is intended for applications such as meat temperature measurement, while a wired probe is useful for grilling and remote measurement. It also includes a backlit LCD, recalibration function, magnetic mounting, temperature hold, Celsius and Fahrenheit selection and a programmable high temperature alarm. Its measurement range is -50°C to 300°C.

B. Working Principle

R-Tek Digital Probe Thermometers work by using a temperature sensing element located inside the probe. When the probe contacts or penetrates the material being measured, the sensor responds to its temperature.

The electronic circuit converts the sensor signal into a digital temperature value, which is then displayed on the LCD screen. The user can monitor the temperature until the reading becomes stable.

Models with folding probes provide convenient portable measurement, while models with wired probes allow temperature to be checked at a separate sensing location. Functions such as data hold, MAX and MIN memory and temperature alarms help users record or monitor important temperature conditions.

C. Why It Is Used

Digital probe thermometers are used when direct and quick temperature measurement is required. Their probe design allows users to measure the internal or contact temperature of food, liquids, refrigerated products and other suitable materials.
