Introduction
The portable smelting thermometer is a high-precision special instrument specially developed for the rapid measurement of molten metal temperature in the smelting process of smelting and casting industries.
The instrument takes high-performance single-chip microcomputer as the core, adopts high-precision measurement sensor parts, and adopts various intelligent processing technologies to ensure long-term stable operation of the instrument. Improve the anti-interference ability of the instrument

Main feature:
W330 portable smelting thermometer adopts integrated design of temperature measuring instrument and temperature measuring gun. According to the characteristics of harsh working environment and high temperature in smelting temperature measurement, it adopts shockproof and high brightness LED digital tube display and full metal casing design, so it is more For durability.
(1) The temperature value is automatically maintained when the temperature is measured.
(2), the light, the buzzer synchronization prompts the end of the temperature measurement (lift the test gun).
(3), alarm function such as break, over-range, power supply undervoltage.
(4), the power supply uses nickel-metal hydride rechargeable battery (usually can measure temperature thousands of times after one charge).
(5) After the power is turned on, the power is automatically turned off after no signal input for 2 minutes.
This instrument has excellent anti-interference ability due to the latest anti-interference measures. When the intermediate frequency furnace is energized and smelted without power supply, the temperature can be measured in the furnace.
