Holdpeak Manometer Dual Port Pressure Gauge for HVAC, 11 gas pressure units (inH20,psi,bar,mbar,kPa,inHg,mmHg,ozin2,ftH20,cmh20,kgcm2) 4 measuring modes (Max, Min, Avg, DIF).

This product can measure differential pressure, positive pressure and negative pressure, with the following optional measurement units: inH20,psi,bar,mbar,kPa,inHg,mmHg,ozin2,ftH20,cmh20,kgcm2. Equipped with simple hose connection device. It is applicable to the measurement of ventilation and air conditioning system, on-site calibration, and troubleshooting of any gas pressure system. Simple operation and clear reading are indispensable measuring tools for HVAC technicians, operation and maintenance engineers and scientific researchers.

Description:

Measurement range: ±30psi; Accuracy: ±0.3%FS ; Repeatability: ±0.25%FS ; Linearity/Hysteresis: ± 0.1% FS of full scale

 

Two input ports - based on a dual port design, one for positive pressure testing and one for negative pressure testing, using these two ports together makes it easy to determine the air pressure differential. The air pressure tester comes with two 4mm diameter hoses and a standard 1/8" hose adapter and is suitable for testing and replacing gas valves on natural gas furnaces, diagnosing instantaneous water heaters, and measuring static pressure in piping, etc.

Zeroing & Data Hold - "Zeroing" function is supported to clear remaining data and ensure accurate gas pressure readings are obtained. An essential tool for any HVAC technician checking airflow pressure, static pressure or pressure switches when installing and maintaining commercial air conditioning systems.

Time Display & Data Record- This Manometer would be record 99pcs data with time stamp, which help to easier to  view the maximum, minimum.and average values and analyze the data.
