GrayWolf Sensing Solutions
Zephyr II+ Manometers with 3-Function Probe Specifications

Measuring Temperature, Humidity, Dewpoint, Pressure, Air Flow

GrayWolf Zephyr II+ micro-manometer with three function probe

Zephyr II+ with three function probe


Advantages:

The Zephyr II micromanometers measure differential pressure with a built-in micromanometer & can measure flow using a pitot probe. The optional 3-function probe adds the ability to measure

  • temperature,
  • relative humidity and
  • air flow measurement using a hot wire thermoanemometer.

A two prong Omega style connection provides an additional connector for numerous type ‘K’ thermocouple temperature probes.

Multiple Parameter

Measure Differential Pressure alone, add temperature with a K thermocouple temperature probes, or with a 2300 AHTS 3-function probe (%RH/Temperature/Airspeed) or measure airspeed and VFR with a pitot probe.

Standard inputs

  • Built-in, auto-zeroing, micro-manometer
  • 'K' type thermocouple
  • 3-function “smart” probe 
Large and clear display
  • Measure up to 4 variables simultaneously
  • Scroll through all other readings on the display
  • Wide viewing angle ensures readings are always visible
  • Automatically updated when probes plugged in
  • On screen instructions for easy operation
 
Data port (Zephyr II+ only)
  • Allows logged data to be downloaded to Desktop PC for analysis
  • Manual or automatic datalogging available

Advanced datalogging for unattended surveys

Intuitive menu system

  • Minimum training required
  • Easy to use
  • Screen prompts guide user through operation

Reporting and Analysis Software

Simple desktop data analysis and reporting of logged info with included WolfSense PC desktop analysis software (Zephyr II+ only)
Optional Mobil PC interface

Connects Zephyr II or II+ to a Pocket PC or Notebook PC with WolfSense application software and a serial card (model ACC-SCCF). May be interfaced simultaneously with any GrayWolf DirectSense probe. When interfaced with WolfSense PPC or LAP, stores ALL survey info; data AND text/graphic/audio notes and includes easily accessible, on-board parameter tips, government and industry guidelines.
