Portable Thermometer

1. Product Introduction

The KDW330 portable smelting thermometer is a high-precision special instrument developed for the rapid measurement of molten metal temperature in the smelting and casting industries.

The instrument is centered on high-performance single-chip microcomputer, uses high-precision measurement sensor parts, and adopts a variety of intelligent processing technologies to ensure the long-term and stable operation of the instrument. It improves the anti-interference ability of the instrument.

This instrument can be used with a suitable thermocouple to perform precise and rapid temperature measurement in various smelting occasions.

2. Product Features

The KDW330 portable smelting thermometer uses  an integrated design of the thermometer and the thermometer gun. According to the harsh working environment and high temperature on the melting temperature measurement site, it adopts shock-resistant and high brightness LED digital tube displayer and all-metal shell design, so it is more durable.

This instrument has the following functions:

1) The temperature value is  maintained automatically when the temperature is measured.

2) The lighting and beep  prompt the end of the temperature measurement (lift the test gun) function synchronously.

3) Alarm functions such as off-couple, over-range, power supply undervoltage etc. 

4) The power supply uses a nickel-hydrogen rechargeable battery (the temperature can  be measured thousands of times after one charge) generally.

5) Turn on the power supply and  disconnect the power supply function after 2 minutes of no signal input automatically.

This instrument can be equipped with 5 types of thermocouples in the same machine.

Since this instrument adopts the latest anti-interference measures, it has excellent anti-interference ability. The temperature measurement in the furnace can be measured  no need to turn off power  when the medium-frequency furnace is turned on and melted.

3. Technical performance indicators

1) Measurement range and measurement accuracy

2) Resolution (℃): 1

3) Response time (S): 1

4) Power supply: rechargeable battery DC6V±10%

4. Installation and operation

1) Installation of test gun

Open the packaging box, take out the three sections of the test gun, hold the copper head section with your hand, and rotate it one by one to avoid twisting the compensation wire and breaking the welding. There should be no shaking feeling after tightening.

connect the two-core plug in the barrel to the same type of two-core plug in the connection sleeve on the portable smelting thermometer Carefully ( make sure to plug the signal plug to the bottom when inserting the socket), then insert the test gun into the connection sleeve and tighten it with the stop screw.

2) Operation of portable smelting thermometer

Press the power switch (ON/OFF) on the instrument surface panel and the  moniter immediately displays "" and then displays the thermocouple model to be equipped (  / is S type,  / is R type,  / is B type,  / is WRe3/25, and  / is K type)

When the thermocouple is not plugged in, the instrument displays " ". When the thermocouple is plugged in and the contact is good, the instrument displays ambient temperature (the instrument of the B index number shows ""), and the temperature measurement can be performed at this time. When measuring the temperature, insert the thermocouple into the metal liquid at a depth of ≥20mm to ensure fast, accurate and stable. When the measurement indicator light (H) is on (sound and light prompt), the thermometer should be lifted immediately (usually 3 to 5 seconds). The instrument automatically displays and maintains the measured temperature value.

Replace the used thermocouple, insert a new thermocouple (removal even if it is not damaged, stop, and reinsert the test gun), and re-temperature measurement.

The instrument displays "-1" means that the thermocouple is not plugged in or the contact is not good.  Push it in or rotate the paper tube slightly to make it have good contact.

The input signal of the instrument displays "-000" is connected in reverse.

The meter displays the input signal "1" exceeds the range.

The instrument displays "HELP" to indicate that the battery is undervoltage.

The instrument should be turned off in time after the measurement is completed to avoid waste of battery.

5. Supporting kits

1) Test gun: The model of the test gun must match the instrument model, and the specifications are 1.5~2.5m.

2) Charger

3) Quick head
