Portable digital pressure gauge providing highly accurate measurements in a robust housing

Special features:

• High level of accuracy and long-term stability
• Little zero point drift or hysteresis; largely independent of temperature
• Available for 4 measuring ranges
• Analogue output (optional)
• Toggle on/off time constants for attenuating the display during pressure fluctuations
• Can be calibrated
• The EMA 84 is a portable, battery-powered digital pressure gauge providing highly accurate measurements of positive and negative differential pressures. Because it is durable and easy-to-use, the EMA 84 lends itself well to maintenance work and customer service applications for heating, air-conditioning and ventilation units, where it can be used for monitoring filters, measuring fireplace drafts, etc. Its precision and reproducibility also make the EMA 84 is highly suitable for use in laboratory applications.
• The instrument is available with an ISO factory calibration or DAkkS-accredited calibration certificate (optional).

Additional Information:

• Delivery Time: 5-6 working weeks
• Packaging Details: Box packing

The DPT-Flow-Batt is an on-site display designed for air handling units to measure the air flow on centrifugal fans. The DPT-Flow-Batt can also be used in the duct system as an on-site display for flow. The device can be used with several different measurement probes such as FloXactTM or pitot tube, and air dampers. The requirement is that the K-value of the measurement probe or damper is known.

The DPT-Flow-Batt series air flow transmitters are engineered for building automation in the HVAC/R industry. The most technologically advanced transmitters on the market, measuring volume flow, velocity, and static and differential pressure. The DPT-Flow-Batt series devices can be connected directly to the pressure measurement points in a centrifugal fan, providing accurate flow measurement of the fan. The smart user interface enables easy selection of settings according to the selected fan or in-duct measurement probe

DPT-Flow-Batt series devices include:
• Two field selectable functions: o Measure in-duct volume flow, velocity or differential pressure o Measure airflow across centrifugal fans
• Multiple field selectable measurement units: o Volume flow: m3/s, m3/h, cfm, l/s o Velocity: m/s, ft/min o Pressure: Pa, inWC, mmWC, kPa, mbar

Application:
DPT-Flow-Batt series devices are commonly used in HVAC/R systems for:

• Air flow monitoring across centrifugal fans and blowers
• In-duct air flow monitoring

Portable digital pressure gauge for measuring differential pressures and flow rates.

Special Features:

• High level of accuracy and long-term stability
• Little zero point drift or hysteresis; largely independent of temperature
• Available for 4 measuring ranges
• Scalable analog output
