Differential Pressure Manometer 8897

The CEM DT-8897 measures gauge and differential pressure, air velocity, air flow and temperature. It is built for HVAC technicians, facility engineers and electricians who need a single handheld instrument for duct balancing and environmental checks.

Practical limits of USB interface

Data transfer relies on a USB-to-UART bridge controller that requires a compatible driver on the host computer. The large backlit LCD shows pressure, velocity or flow together with temperature, but the standard package ships without batteries because air-freight rules prohibit them.

Installation and common issues

Power the meter with locally sourced batteries, then use the zero-adjust and DIF functions to calibrate pressure readings before logging. Users often overlook the area-dimension setup (up to eight points) which is essential for accurate flow calculations, and the English manual must be requested from customer service after purchase.

Questions about this item

Which model should I choose between the DT-8897 and the DT-8897H?

The DT-8897H adds a hot wire anemometer for air velocity measurement, while both models measure gauge/differential pressure, air flow, and temperature with a large LCD display.

What does the differential pressure range cover in practical use?

The instrument measures gauge and differential pressure, air velocity, air flow, and temperature simultaneously, with zero adjust and DIF functions for accurate readings in HVAC and ductwork.

What does the USB interface actually let me do?

The USB to UART bridge controller enables data transfer to a PC for logging pressure, air velocity, air flow, and temperature readings captured with the relative time clock on MAX, MIN, and AVG.
