(Previously known as the Gravity Analog ORP Sensor / Meter)
Every project is different; sometimes, you need high-accuracy digital readings. And other times, you only need a basic analog output. For those of you looking to add ORP measurements to your device but want something simple, the Atlas Scientific Gravity ORP Meter/Sensor is for you. This low-cost ORP meter gives you the same capabilities found in basic hand-held meters, with an easy way of capturing the data.
