Holdpeak Manometer Dual Port Pressure Gauge for HVAC, 11 gas pressure units (Bar,mmHg,Ozin2,Kgcm2,Psi,inH2O,kPa,ftH2O,inHg,cmH2O,Mbar. ) 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: ±2.000psi; 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.

Buttons Operation:
1.Power on/off Button: Short press to turn on or off, long press to select whether to turn off automatically, and press HOLD to select ON or OFF. ON means automatic shutdown is on (automatic shutdown time is about 25 minutes), and OFF means automatic shutdown is off.
2.HOLD Button Power on status:Short press is the data holding function. At this time, the "HOLD" symbol will appear on the display, and then short press to cancel the holding function. If there is a base number before measurement, press and hold it for more than 5 seconds, the display of the screen will show “---”, and the instrument is reset to zero.
3.UNITS Button Power on status:Unit conversion function. Press this button to cycle between units, Bar,mmHg,Ozin2,Kgcm2,Psi,inH2O,kPa,ftH2O,inHg,cmH2O,Mbar.
4.DIF Button Power on status: Difference value button, the pressure value after pressing the button minus the pressure value before pressing the button. 5.RFC Button on status: Press the button for a short time to enter the recording mode, and press and hold button for 5 seconds to exit the recording mode. In the recording mode, continue to press the button briefly to view the maximum, minimum and average values recorded in the measurement. Other functions cannot be operated.
6.LIGHT Button on status: Press this button once to turn on the backlight, and press it again to turn off the backlight, or the backlight will turn off automatically after 30 seconds.
