Digital Vacuum Gauge HVAC Vacuum Test Gauge Pressure Gauge Kit with 13 Units

Description: Description: This 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).And 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.). Digital vacuum gauges parallel with vacuum pumps (making vacuum) in utilization and further, refrigerant gauges (emulation or digital) are often employed to monitor refrigeration system.Warm tips: product buttons have old and new versions, random delivery. 【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】The vacuum gauge uses a professional sensor for more accurate measurement. Measuring range: 0-100KPa/14.50Psi, resolution: 0.001Kpa/1umHg, accuracy: ±0.1%FS. The HVAC vacuum gauge supports 13 units: mmHg, inHg, umHg, ftH2O, cmH2O, inH2O, Pa, Kpa, mbar, bar, Kg/cm², psi, oz/in².【Two Working Modes & 4 Calibration Modes】Meter has two working modes,normal and monitoring.The normal mode (default mode) is when the gauge is switched on,and press the "DIF" button" for monitoring mode in short time.Also,the gauge has four calibration modes.Mode 1: Atmospheric calibration (exercised under atmospheric pressure),Mode 2:Vacuum calibration (performed in a vacuum environment),Mode 3: Custom calibration (under specified negative pressure),Mode 4: Restore factory calibration values.【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 and battery,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. 2 Working Modes & 4 Calibration Modes2 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. Under the monitoring mode, the temperature is showed normal, with the SET light on the screen flashing, whose cycle is 1Hz. The buzzer sounds once every three seconds. If the current pressure is lower than the designated pressure at this time, an alarm will run. In which 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.4 Calibration Modes：Under normal mode, long press “HOLD” to enter calibration mode1.Atmospheric correction: showing CAL---1 means short pressing the "HOLD", and at this time the show of the lower row of Nixie tube shifts from empty to sequentially lit ------, and returns to the normal mode. This calibration is just a translation curve (exercised under atmospheric pressure ) (the air pressure needs, during calibration, greater than 85kap, otherwise a fault will appear).2.Vacuum calibration: showing CAL---2 , short press the "HOLD1". At this time, firstly judge whether the current air pressure is lower than 15kpa. If it isn’t, the lower row of Nixie tube will exhibit Error, and press any key to return to the normal. If it is, the exhibition of the lower row of Nixie tube will shift from empty to ------, and return to the normal mode. This calibration will change the slope of the curve. (performed in the vacuum environment) (the air pressure needs lower than 15kap, during calibration, otherwise a fault will appear)3.Custom calibration: showing CAL---3,After setting the value（settings range 0-60kpa）, short press the "HOLD" for calibration, and at this time, the exhibition of the lower row of Nixie tube shifts from empty to sequentially lit ------ and returns to the normal. This calibration will change the slope of the curve (under specified negative pressure )4.Calibration mode : resume the factory-set calibration value, showing CAL---4, short press the "HOLD", and the pressure curve will return to the factory settings 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 UnitsThe 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°CStorage temperature：-20~50°CTemperature scale：-10~50°CTemperature resolution：0.1°CMeasurement cycle：0.5sVacuum range：0~100 Kpa 5 Types Of ConnectionDigital vacuum gauges are always used with vacuum pumps (to generate vacuum).In addition the vacuum gauges are often used with digital manifold gauge (https://www.ebay.com/itm/185999252198) to monitor refrigeration systems.
