The SHO-GAUGE™ app is designed to be operated in conjunction with the TFT SHO-GAUGE™ smart pressure gauge. Doing so enables the user to monitor the pressures captured by the device in psi, bar, and kpa. The firmware update function in the application can be used to update the board code on the SHO-GAUGE™ over Bluetooth without opening the pressure gauge. The TFT SHO-GAUGE™ smart pressure gauge is designed to quickly determine pressures present in a fire hose line, hose line apparatus, monitor, or pitot tube then wirelessly transmit the rate to a nearby smart phone or tablet. Firefighting, training, or testing operations that utilizes hose lines, nozzles, or hose line apparatuses is a potential application. Read the manual before operation.
