Mastercool 99903 4-Valve Digital Manifold

The Mastercool 99903 is a 4-way digital manifold that displays pressure, saturated temperature, actual temperature, superheat, subcooling temperatures as well as vacuum. The 4-valve manifold can record and store 24 hours of data directly on the manifold memory. This HVAC digital manifold comes preprogrammed with over 60 refrigerants and can be updated with new refrigerants via a USB connections and the Mastercool Software. Residential and commercial refrigeration technicians will love the convenience, accuracy and data logging capabilities this 4-way AC digital manifold provides when analyzing a HVAC system. The Mastercool 99903 is perfect for the technician who already has the hoses, thermocouple, and vacuum sensor and just needs to replace or upgrade his equipment as this model does NOT include any accessories.


Key Features
  • Preprogrammed with 63 refrigerants
  • Records up to 24 hours of data on manifold memory / data can be downloaded to computer with Mastercool software
  • Shows corresponding saturation, dew or bubble point temperature for current pressure
  • Shows sensor/ thermocouple temperature when connected
  • Calculate superheat and subcool temperatures when using a thermocouple
  • Shows vacuum when vacuum sensor cable is connected
  • Large 3/8” VAC port
  • ¼” M-Flare connectors

Overview

The 99903 digital manifold is able to record and store data up to 24 hours or 15 different jobs directly on the manifold memory. The data can be viewed in real time on a computer or downloaded when the manifold is connected to a computer using a USB cable and the Data Logger Software. The software allows the service technician to open the appropriate job on the computer and view, zoom, and evaluate the data in real time or review after it has been downloaded. The software has different display functions so the technician can view different parameters simultaneously or separately. The data will be displayed with the correct measurement specification for each reading.

This AC digital manifold is ideal for a technician to quickly and accurately get the data to diagnose, vacuum or charge an HVAC system using the four ports. When used with a thermocouple clamp, the manifold will display the current temperature (°F or °C) as well as calculate the superheat or subcooling temperatures.

In addition, this digital manifold will display the vacuum measurement in Micron, mBar, KPa, Pa, Torr, MTorr, or mmHg when the vacuum sensor cable is connected.

The VAC port is a 3/8” ball valve connection that has a 3/8” bore for increased flow using the vacuum pump.

The 99903 digital manifold is constructed of durable ABS material with a protected rubber boot for years of service. It is powered by one 9V DC battery with a battery life of about 30 hours depending on usage. It does have auto-off after 15 minute of inactivity that can be disabled as well as a low battery indicator. An optional AC/DC adapter (p/n 99334-110) can be purchased separately.

If you would like to purchase a complete manifold gauge set, the Mastercool 99961 includes the manifold, 3-60” ball valve hoses, one black vacuum hose, vacuum sensor with cable, clamp-on thermocouple, data logger CD and USB cable.
