Metrix+ DT 305S K-Type Digital Thermometer 1200C Temperature Meter

A. Product Overview

The Metrix Plus DT 305S is a portable K type thermocouple digital thermometer developed for accurate temperature measurement in industrial, commercial and technical applications.

It features a large 19999 count digital display and provides a resolution of 0.1 degree Celsius or 0.1 degree Fahrenheit. The instrument takes approximately 2.5 readings per second, making it suitable for routine inspection as well as process temperature checking.

The DT 305S supports different K type thermocouple probes depending on the temperature range and application.

The standard TP 01 probe measures temperatures from minus 50 to 250 degree Celsius.

The optional TP 02 probe can be used for high temperature measurements from 0 to 1200 degree Celsius.

The thermometer can store up to 100 sets of measurement data, allowing technicians to record and recall previous readings during inspections or maintenance work.

The standard package includes the DT 305S thermometer, TP 01 temperature probe, batteries, technical manual and packing box.

B. Working Principle

The Metrix Plus DT 305S works using a K type thermocouple temperature sensor.

A K type thermocouple is made using two different metallic conductors. When the measuring junction of the thermocouple experiences a change in temperature, a very small electrical voltage is generated.

This phenomenon is known as the thermoelectric or Seebeck effect.

The DT 305S receives this electrical signal from the connected K type probe and converts it into a temperature value. The measured temperature is then shown on the digital display in either degree Celsius or degree Fahrenheit.

The type of probe connected to the thermometer determines the practical temperature range and the type of surface, liquid, air or process temperature that can be measured.

For normal temperature measurements, the supplied TP 01 probe can be used from minus 50 to 250 degree Celsius.

For considerably higher temperature applications, the optional TP 02 probe allows measurements up to 1200 degree Celsius.

C. Why It Is Used

The Metrix Plus DT 305S is used when technicians need a portable and accurate instrument for checking temperatures at different points of a process, machine or installation.

Unlike a permanently installed temperature controller or indicator, a handheld K type thermometer can be carried from one location to another and connected to a suitable thermocouple probe.

It is useful for:

• Furnace temperature checking
• Oven temperature measurement
• Industrial heating equipment inspection
• HVAC troubleshooting
• Process temperature monitoring
• Machinery maintenance
• Laboratory temperature testing
• Production quality checks
• Preventive maintenance
• Electrical and mechanical maintenance
• Heating system inspection
• High temperature process measurement
• Equipment commissioning
• Temperature comparison and verification

The high and low temperature alarm functions are particularly useful when an operator wants to identify temperatures outside predetermined limits.

The 100 set data storage function is useful where several temperature readings need to be taken and reviewed during inspection work.

D. Suitable Buyers

The Metrix Plus DT 305S is suitable for buyers who regularly perform temperature measurement, maintenance or inspection work.

Typical users include:

• Industrial maintenance engineers
• Electrical maintenance teams
• Mechanical maintenance engineers
• HVAC technicians
• Furnace manufacturers
• Oven manufacturers
• Heating equipment manufacturers
• Process industries
• Manufacturing plants
• Quality control departments
• Testing laboratories
• Research laboratories
• Production engineers
• Facility management teams
• Service engineers
• Machine manufacturers
• OEM companies
• Calibration and testing professionals
• Industrial contractors
• Technical service companies
