- Pressure range covers 29 in Hg to 1000 psi
Professional HVAC Diagnostic Tool
The JB Industries DM4-Z is a four-valve digital manifold gauge built for technicians who service multiple refrigerants. Its transflective display remains readable in bright sunlight and the water-resistant housing with protective boot withstands daily field use. Laser-welded stainless-steel transducers deliver reliable pressure data across a wide operating range. The kit includes four 60 in hoses for immediate connection to system ports.
Pressure Range and Accuracy
The gauge measures vacuum down to 29 in Hg and positive pressure up to 1000 psi with a stated accuracy of +/- 0.5 percent full scale and 1 to 2 percent of reading. This single specification determines whether the instrument covers the systems you service. Technicians working exclusively on ultra-high-pressure CO₂ transcritical racks will find the upper limit insufficient. Buyers who need documented NIST traceability should verify certification separately.
Build Integration
Quarter-turn handles open and close valves fully for faster evacuation and charging cycles. Universal K-type clamp thermocouples connect directly to the unit for real-time superheat and subcooling calculations without extra adapters. The aluminium block and Zeppelin design reduce weight while maintaining durability. Users who require wireless data logging or smartphone integration will not find those features on this model.

Questions about this item
What does the 1000 psi pressure range mean when I'm using this manifold on a real job?
The 0 to 1000 psi scale covers high-side readings for common refrigerants, so you can charge and diagnose without switching gauges.
How does the 3/8 inch connection affect what hoses or fittings I can use?
The 3/8 inch port accepts standard 3/8 inch flare hoses and allows faster evacuation than smaller ports.
What clearance do I need for the 60 inch hoses when routing them around a condenser unit?
Each hose is 60 inches long, giving you five feet of reach to position the manifold away from hot surfaces or tight corners.
