P51-870 TITAN Digital Manifold
View Larger


The YELLOW JACKET® P51 TITAN™ Digital Manifold Series provides ultimate system measurements with ease. This 4-valve manifold provides fast and accurate measurements for refrigeration and a/c systems. Measurements are displayed on a backlit digital display and can be transmitted via Bluetooth® to a Smartphone for even further analysis. Local display of system pressures and temperatures, superheat and subcool provide instant analysis. When connected to your Smartphone, target superheat and subcool are easily attained, along with all the other capabilities of the ManTooth™ app. The flagship YELLOW JACKET P51-870 TITAN features a 4.3” full color touchscreen graphic display with digital and graphical representation of pressure and temperature measurements. It also features on-board data logging and standard vacuum sensor and measurements (vacuum sensor included). A 4-pak of hoses is included as well as two temperature clamps and a backpack carrying case for safe storage.

IMPORTANT SET-UP INFORMATION: The touchscreen calibration of your new P51-870 may have been compromised during shipping. To recalibrate, follow these quick steps:

  1. When the device is powered on, press the power button three times in quick succession (this should power the device off).
  2. Power the device back on to prompt calibration.
  3. Tap the three -flashing dots as they appear on the screen. For the best calibration, use a fine tip to tap the center of each dot.

When the calibration is complete the device will startup normally. This process is demonstrated here: https://yellowjacket.com/videos/p51-870-recalibration-guide/
