SRH3 – Psychrometer

Get your superheat on.

Where to Buy

  • In-duct target superheat & target evaporator exit temp
  • Wet bulb, temps, dew point, and %RH
  • Hands-free testing
  • 38″ telescoping probe
  • Quickly takes readings from the center of the duct

Right readings in the right spot.

Where’s the optimum place to take in-duct measurements? Near the evaporator. That’s why we developed the SRH3 in-duct psychrometer to be flexible enough and long enough to get close. It allows you to properly charge a fixed orifice system by quickly determining your target superheat. This amazing tool also helps determine optimum airflow across the evaporator with a target evaporator exit temperature test.

Telescoping accuracy.

We built the SRH3 with a 38″ telescoping probe. This unique tool has a laser etched ruling and flattened edges for easily locating proper measurement points within a duct while also ensuring that your probe is properly aligned. Also, its dual display has a bright, backlit screen to clearly show you every reading. The rugged rubber boot with probe clips makes sure the SRH3 is ready for any job.

SRH3 features:

  • Measures temperature and %RH
  • Calculates wet bulb and dew point
  • Slim 38″ telescoping probe
  • Fast response time
  • Depth and direction indicators
  • Hands-free testing with stabilizing cone and magnetic hanger
  • Calculates target superheat and target evaporator exit temperature

What’s Included:

  • (1) SRH3 In-Duct Digital Psychrometer 
  • (1) Stabilizing Cone
  • (1) Blow-molded Case with Padding
