Characteristics

The NJ330 portable melting thermometer adopts an integrated design of thermometer and temperature gun. Based on the harsh working environment and high temperature of the melting temperature measurement site, it adopts a shock resistant and high brightness LED digital display and a fully metal shell design, making it more durable.

This instrument has:

1. The temperature value is automatically maintained during temperature measurement.

2. The function of synchronously indicating the end of temperature measurement (lifting the test gun) through lighting and buzzing sounds.

3. Alarm functions such as disconnection, over range, and power undervoltage.

4. The power supply adopts nickel hydrogen rechargeable batteries (which can generally measure temperature thousands of times after one charge).

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

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

This instrument has excellent anti-interference ability due to the adoption of new anti-interference measures. When the intermediate frequency furnace is powered on for melting, temperature measurement can be carried out inside the furnace without cutting off the power.
