953-ZQJ-2000 leak detector

1. Product Overview

ZQJ-2000 leak detector is a fully automated, LCD screen and digital tube dual display leak detector, it is composed of molecular pump (FF-40/25J), backing pump (RV4), mass spectrometry chamber, combined valve body, circuit board, LCD screen and operation buttons, etc., the leak detector built-in RS232 communication interface, external control IO interface and printer interface, at the same time, users can also choose wireless remote control and other accessories.
The outline structure of the instrument is shown in the following figure:

3. Working environment

Ambient temperature	5℃～45℃
Relative humidity of the air	<80%
Supply voltage	220VAC±10%, 50Hz, single phase, with ground wire
There is no strong electromagnetic field in the vicinity of the 8A instrument	There is a ground wire with a solid ground maximum current
There is no strong electromagnetic field interference, no violent vibration, no corrosive gas near the instrument; The room is well ventilated to avoid helium interference
It is recommended that the backing pump vent be connected to the outdoor or other exhaust system via an appropriately sized hose to reduce helium background in the test environment.
Maintain air circulation in the test environment to reduce the influence of the helium background signal in the environment on the measurement results

 
 

4. Storage environment

Ambient temperature	-15℃～60℃
Relative humidity of the air	<90%
If it is not used for a long time, it is best to store it in a dry and dust-free environment, and when using it again, it is recommended to turn on the machine for more than 4 hours before use

 

5. Power supply and external interfaces

●Leak detector power supply: including power cord and leak detector main switch;
● External interface: including RS232 interface, external control IO port and printer interface. Among them, the RS232 interface and the external control IO interface are the standard configuration interfaces of the system; The RS232 interface enables computers and other devices with standard 232 interfaces to communicate with the leak detector to control the leak detector or read data from the leak detector; The external control IO interface realizes the external switch to control the leak detector or the leak detector outputs digital and analog to external devices;
