I was comparing some digital gauges at a supply house and another customer told me his set had remote temperature sensors. The sensors are placed in the ductwork and measure delta t across the evaporator coil as well as wet and dry bulb temp. The gauges update temperature information by way of transmitter and receiver. I have since forgotten the brand name. The only set I have found so far is made by Stargate, model number SG3000.

I have never heard of this company, and have not been able to find any reviews of the product. Are any of you familiar with these? Do you know of a similar product?

I think this feature is very useful. I still use analog gauges and don't mind calculating superheat and subcooling the old fashioned way. However, realtime temperature readings sound useful for installs as well as troubleshooting.

Thanks,
J
