Feature
●【Multi-Functional Intelligent Digital Vacuum Gauge】Vacuum gauge is versatile,it can accurately measure micro change of pressure in vacuum.Also,you can gauge the real-time pressure of the refrigeration system in vacuuming,thus gathering information relevant to dehydration and cleaning foreign body.In addition to monitoring the vacuum system in real time,it can also identify the quality of the vacuum pump,measure whether the system is leaking,obtain the status of the refrigerant charging,etc.
●【High-Precision Vacuum Sensor &13 Measurement Units】HVAC micron gauge is accurate and reliable in measurement,and the range is reduced to 0-100Kpa/0-750,000microns,which further improves the measurement accuracy(measurement accuracy:±0.1%FS,minimum resolution:1 micron).Built-in high-precision vacuum sensor,which is not only accurate and reliable,but also quick to respond.It has 13 measurement units (mmHg,inHg,umHg,ftH2O,cmH2O,inH2O,Pa,Kpa,mbar,bar,Kg/cm²,psi,oz/in²)which can be switched freely.
●【Two Working Modes & 1 Calibration Modes】Digital vacuum gauge has two working modes,normal and monitoring.The normal mode (default mode) is when the gauge is switched on,and press the "SET" button" for monitoring mode in short time. In the monitoring mode, the screen displays a flashing SET indicator,and the buzzer sounds.In addition, the vacuum gauge is also designed with a calibration mode,long press the "CAL" button to enter calibration settings,automatically exits upon completion.
●【Sound & Light Dual Alarm】Vacuum gauge hvac can be set to an pressure alarm value and has a buzzer alarm function.In monitoring mode,if the current pressure is lower than the set pressure at that time,the buzzer will alarm continuously and the backlight will flash.It also has a temperature measurement function,when the refrigerant hose is connected to the air-conditioning pipe,it can display the temperature in the air-conditioning pipe in real time,helping you to judge the degree of vacuuming.
●【Humanized Design】HVAC vacuum gauge adopts a high-definition LCD display with backlight function for better readability,and it can work normally even in a dim environment.Vacuum gauge is designed with non-slip rubber on the both sides,which can effectively prevent slipping and have a comfortable grip.Also,the vacuum gauge comes with an extension connector,saving you the time of buying extra.It is a good helper for AC technicians who do air conditioning charging or automotive AC work
●【2 Years Warranty】Our digital vacuum gauge provides a two-year warranty. If you have any questions during use, please feel free to contact us, we will reply you in time. Note: Digital vacuum gauges are always used with vacuum pumps, and are often used in conjunction with refrigerant gauges to monitor refrigeration systems.
Description
2 Working Modes & 1 Calibration Modes
2 Working Modes：
The mode is normal when the device is turned on, and in short time press the "DIF" button for monitoring mode. Again short press it to exit the monitoring mode.In the monitoring mode, the screen displays a flashing SET indicator, and the buzzer emits a single beep every three seconds, with a frequency cycle of 1Hz. If the current pressure is lower than the designated pressure at this time, an alarm will run.During this period, the backlight flashes and the buzzer alarms continuously, whose frequency is 1Hz. The alarming will automatically disappear, or pressing any key, or automatically disappear after 30 seconds, when current pressure is higher than the set pressure, and after that, the device is still in the monitoring mode.
1 Calibration Modes：
Calibration mode : Long press the "CAL" button to enter calibration settings,automatically exits upon completion.
Our digital vacuum gauge to accurately measure micro change of pressure in vacuum. You can use the vacuum gauge to monitor the performance of refrigeration systems and heat pumps (usually during commissioning).
You can gauge the real-time pressure of the refrigeration system in vacuuming, thus gathering information relevant to dehydration and cleaning foreign body (such as oil, external gas and etc.).
13 Measurement Units
The vacuum gauge is set up with 13 measurement units (mmHg, inHg, umHg, ftH2O, cmH2O, inH2O, Pa, Kpa, mbar, bar, Kg/cm², psi, oz/in²) which can be switched at will.
Buttons：
1. Power Button::Long press to turn on the device, and press again the power button to choose turn on or off the backlight.
2. Unit Button：Press the “UNITS” to choose the needed pressure unit.
3. MAX Button：Press the “MAX” to switch between the maximum and the minimum pressure.
4. DIF Button：“DIF” is identical with “SET”. Press “DIF” for some time accompanied by “C/F” and “MAX” to designate the alarming value of vacuum pressure, and confirm by pressing “HOLD”.
5. C/F Button：Press “C/F” to switch the unit of temperature.
Technical Parameters：
Working temperature：-10~50°C
Storage temperature：-20~50°C
Temperature scale：-10~50°C
Temperature resolution：0.1°C
Measurement cycle：0.5s
5 Types Of Connection
Digital vacuum gauges are always used with vacuum pumps (to generate vacuum).In addition the vacuum gauges are often used with digital manifold gauge (B0922S5TT6 / B0936JWQ9S) to monitor refrigeration systems.
