Uei Test Instruments EM152 Digital Manometer Differential Backlit LCD ±60 in wc accessory

SKU CH-VZMS-5W5JZ

Measures differential gas pressure from –60 to 60 in wc with ±0.3 % full-scale accuracy on a backlit LCD

  • Measures differential pressure up to ±60 in wc for HVAC diagnostics
  • Backlit LCD ensures clear readings in dim or bright conditions
  • Accuracy of ±.3 % of full scale supports reliable gas pressure checks
  • Auto power-off extends 9 V battery life during field use
  • Data hold function freezes display for easy recording

Purpose and user

The Uei Test Instruments EM152 is a digital manometer built for differential gas-pressure measurement up to ±60 in wc. It suits HVAC technicians and field engineers who need a portable, battery-powered instrument for quick on-site checks.

Interface limits

The device connects through a 1/4 in hose barb and provides an accuracy of ±.3 percent of full scale. A backlit LCD and data-hold function aid readability, while the lack of a data interface means readings must be recorded manually. Auto power-off helps conserve the 9 V battery during intermittent use.

Build and daily use

The unit arrives new with the required 9 V battery included and no calibration certificate supplied. Its handheld form and hose-barb fitting allow direct connection to test ports without additional adapters, making it practical for routine pressure verification in gas applications.

Questions about this item

Should I choose the EM152 model or a different pressure range for gas system testing?

The EM152 covers a differential range of ±60 in wc with an accuracy of ±.3 percent of full scale, making it suitable for low-pressure gas applications where that span matches the expected readings.

What does the ±60 in wc range mean when I am measuring furnace manifold pressure?

The instrument reads from -60 to +60 in wc, so a furnace manifold pressure of 3.5 in wc falls well within the scale and the ±.3 percent full-scale accuracy applies across the entire span.

How does the 1/4 in hose barb connection affect the pressure reading in the field?

The 1/4 in hose barb provides a direct barbed fit for flexible tubing, allowing gas pressure to reach the sensor without an adapter and preserving the stated ±.3 percent full-scale accuracy.
