One, purpose:
The ND-W330 hand-held melting temperature measuring instrument is a high-precision special temperature measuring instrument specially developed for the smelting and casting industries to quickly measure the temperature of the molten metal during the smelting process. This temperature measuring instrument takes a high-performance single-chip microcomputer as the core, adopts high-precision measurement sensors, and various intelligent processing technologies, which improves the anti-interference ability of the instrument and ensures the long-term stable operation of the temperature measuring instrument. This temperature measuring instrument is used in conjunction with a corresponding thermocouple and can perform fast and precise temperature measurement in a variety of smelting situations.
Two, characteristics:
The ND-W330 hand-held melting temperature measuring instrument adopts an integrated design with the temperature measuring gun. According to the harsh working environment and high temperature characteristics of the smelting temperature measurement site, it uses a shock-resistant all-metal housing design and a high-brightness LED digital tube display, which is durable. It has the following characteristics:
-
When the temperature measurement in the furnace is successful, the temperature value is automatically maintained.
-
The lighting and buzzer sound synchronize to prompt the end of temperature measurement (the test gun can be picked up).
-
Alarm for open circuit, overrange, and power undervoltage.
-
The power supply uses nickel-hydrogen rechargeable batteries (after one charging, it can generally measure the temperature more than a thousand times). When the power is turned on, if there is no signal input for 2 minutes, the power is automatically disconnected (for power saving).
-
It can be equipped with 5 types of thermocouples. Due to the adoption of very new anti-interference measures, it has good anti-interference ability. When the intermediate frequency furnace is powered on for smelting, it can perform temperature measurement in the furnace without power off.
