Review on 🔬 Fieldpiece PRH2 Digital Psychomotor Analyzer by Todd Atherton

I use it regularly in my job as an HVAC service technician. It accurately calculates the internal and external dry bulb to calculate the superheat for checking or charging the AC system. It's a good work tool, but it has its drawbacks: - it doesn't fit in a shirt pocket - it's too long - it's a bit fragile. Don't twist the top too much or the insides will twist inside the case and damage it. Don't drop it. I broke 2 in 5 years but I'm not good with tools. Temperature registration can be slow.
