Product Description

HT-1890 Digital Manometer Air Pressure Differential Pressure Meter with Large LCD Backlight for HVAC Clean Room Testing


[High Precision Measurement] The ht1890 digital manometer offers exceptional accuracy with ±0.3% fso at 25°c, making it for professional hvac and ventilation system testing. its 11 selectable units (including inh2o, psi, mbar, kpa) provide versatile measurement options for various applications. the device features advanced functions like zero adjustment, offset, and dif for precise calibration.


[Complete Measurement Solution] for hvac technicians, clean room maintenance, and industrial applications, this kit includes everything needed for pressure measurement. the package contains the manometer, user manual, carrying pouch, tubes, and metal accessory (battery not included). its wide measurement range (±55.40 inh2o) handles most pressure testing needs.


[Advanced Data Functions] This digital manometer records max/min/average values with a relative time clock for comprehensive pressure analysis. the data hold function freezes readings for easy recording, while automatic shutdown conserves battery life. these smart features make it ideal for long-term monitoring tasks.


Features:



Large LCD backlight display, providing clear reading.


11 selectable units for measurement, convenient for use.


Max./Min./Average values, and with a relative time clock.


Low battery indicator and pressure unit indicator.


Zero adjustment, offset and DIF function.


Data hold and automatically shutdown function.
