W330 Type Wireless Handheld Digital Thermometer

Specifications

Digital thermometer with the measuring rod be connected together with dislplay part, it is easy to carry and convenient operating.
This instrument has high anti-jamming ablitydue to its meter shell shield. So IT CAN MEASURE TEMPERATURE AT ANYWHERE OF THE WORK SITE.
Model LDT-2002 thermometer has automatic search function to find the stable temperature value to hold and display within 3-5seconds. At the same time to send hinting sound and ture on the measure end indicator for operator to take the probe away from the measuring region.
Considering the actual condition of the work site, the probe also may be bent a certain angle for convenient operating, and the direct insertion mode is used to connect the probe with the instrument for user to change different type probes more easily.
Features as follow:
1. High accuracy, error≤ ± 2
2. Wide measure range: (0-1999)
3. Accept 4 type thermocouple probe
4. Battery voltage alarm function

Feature:

1.Automatic save measuring temperature records

2.Acousto-optic to suggest you the measuring over.(When you hold the lance)

3. It has the function of fault alarm for power line broken,bad connect and overrange .

4.Power adopt nickel metal hydride rechargeable batteries( One charging time,the Lance can used 1000 times )

5.Automatic two minutes after the power input signal no

6.Strong anti-jamming ability

Working principle

W330 type indicator is a sensor to connect with sensor.

Thermocouple temperature measurement is generated when the electric potential after instrument preamplifier device, and then after A/D converter converted into digital quantity, let into the data processing in the computer, and realize the environment temperature automatic compensation, zero since calibration, furnace temperature stable value is automatically and keep.

This instrument is over, when measured with a light, sound synchronous tip measurement buzzer is over, display temperature measurement, and keep a value measurement for a time.
