The Aqua Master Tools C800 Pro automatically measures pH, EC, PPM, TDS, and temperature in your batch tank and doses set amounts the moment values drift from target, keeping irrigation and hydroponic systems dialed in without constant manual intervention. While the C800 Pro handles automation, many growers also use the \u003ca href=\"\/products\/aqua-master-tools-h600-pro-handheld-meter\"\u003eAqua Master Tools H600 Pro Handheld Meter\u003c\/a\u003e for quick manual spot checks.\u003c\/p\u003e\n\u003cp\u003eTwo separate UTP output ports give the C800 Pro modular flexibility: one connects a single pH dosing pump, the other connects up to five EC dosing pumps.

For larger facilities, you can extend the connection to your dosing pumps using the \u003ca href=\"\/products\/aqua-master-tools-utp-cable-c800-pro-15m\"\u003eAqua Master Tools UTP Cable for C800 Pro Controller - 15m\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eA color touchscreen displays real-time values, alarm status, and historical data on the unit itself.
