Temperature & Relative Humidity Transmitter Instrument
Model TAT-420


The transmitter Model TAT-420 is especially designed for monitoring the "Indoor Air Quality" in the air conditioning, heating, and ventilation industry.
Every instrument has terminals for both DC and AC power, and 0-1V, 0-5V and 4-20mA outputs. The heavy, all metal (except for the electronics pod) probe can be used for airstreams that have a wide range of humidity, temperature and contaminants without compromising accuracy. Includes a NIST-traceable Calibration Certificate.

Features
  • Simultaneous measurement of air velocity and temperature
  • Three separate power supplies 110 VAC 50/60 Hz, 220 VAC 50/60 Hz, and 10-30 VDC.
  • Three outputs are standard features: 0-1 VDC, 0-5 VDC, and 4-20 mA DC

Available Options:
  • LCD Display
  • RS232C Data Link
