The SH450 Total Systems Analyzer is quite possibly the most
versatile tool you will ever own. Measure pressure from -14.7
to 725 PSI, automatically calculate and display superheat, sub
cooling, relative humidity, wet bulb, dry bulb and dew point readings
in seconds. Display temperature differential between any 2 of 4
independent temperature channels. Record and display min/max
readings for any channel at the touch of a button. Scan all 4
temperature channels simultaneously. The SH450 is self contained
in a rugged polyethylene case with plenty of room to fit all your
accessory probes.
