Uei EM700 Differential Manometer

Product Description

The UEI EM700 is a differential manometer designed for accurate pressure measurement across two points in HVAC, combustion, and duct systems. Differential manometers read the pressure difference between two ports simultaneously, giving technicians a direct readout without manual subtraction. The EM700 is a single-unit instrument suited for field diagnostics, filter pressure drop testing, heat exchanger leak screening, and gas appliance commissioning. HVAC technicians and service professionals are the primary users of this type of instrument.

The EM700 is used in residential and light commercial applications where precise differential pressure readings are required. Typical use cases include measuring static pressure across air handlers, verifying pressure drop across filters or coils, and checking draft in combustion appliances. It is sold as a single unit and is intended for field service use by trained HVAC technicians.

Key Features

• Differential pressure measurement across two input ports for direct delta-P readings
• Single-unit instrument well suited for portable field diagnostics
• Applicable to duct static pressure testing, filter drop evaluation, and combustion appliance checks
• Compact design appropriate for service bag carry and on-site use

Compatibility

Designed as an OEM-style field instrument for use in residential and light commercial HVAC pressure measurement applications.

Installation Notes

The EM700 is a handheld test instrument and does not require permanent installation. Before connecting to a pressurized system, ensure the system is at a safe operating state and that tubing connections are secure and free of leaks. Follow the instrument manufacturer guidelines for zeroing the unit prior to taking readings. This type of instrument is typically used by licensed HVAC technicians in accordance with applicable service codes and manufacturer commissioning procedures.
