Review on 🔍 Robinair 11910 Digital Low Pressure Gauge by Loren Schmidt

Approximately the same size as a standard pressure gauge, these (HP and OD) fit easily on my Imperial Eastman 4 valve manifold. The meter has a rigid PVC body with a rubber coating that feels durable and should take a knock or two. I use kPa and degrees C. The pressure and temperature readings are easy to set up and only needed for the initial setup. The refrigerant can be changed simply by pressing a button. The LCD is large, clear, and easy to read when looking directly at the sensor, but can be difficult to see when viewed from a certain angle, even with the backlight on. But it's not a problem. There is a slight delay in changing the pressure displayed when setting the on and off control pressures, so this is not ideal for this application. For general use the sensors are great, no need to pull the PT chart to get an accurate SST or SCT. I don't know how accurate the PT conversion is for Zeotric blends like R407c and if it uses saturation point and dew point plots. I am very happy with these sensors and would recommend them, but only time will tell how reliable they are. they are.
