It runs on any 100-240 V mains supply, so it is ready to go straight out of the box in Australia.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous pH display\u003c\/strong\u003e - 0.5\" LED, 3½ digits, reading to 0.01 pH resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e±0.01 pH accuracy\u003c\/strong\u003e after calibration, so small drifts show up before they become a problem.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 A relay, pH 3.5-10.5 control range\u003c\/strong\u003e - can switch a pump, solenoid or alarm at a set point, not just display a number.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e±0.05 pH control accuracy\u003c\/strong\u003e, digitally adjustable set point.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal power input\u003c\/strong\u003e - 100-240 V, 50\/60 Hz, so it runs on Australian mains without a transformer.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring range\u003c\/td\u003e\n\u003ctd\u003epH 0 - 14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e0.01 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±0.01 pH (+1 digit) after calibration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelay contact\u003c\/td\u003e\n\u003ctd\u003e5 A at 100-240 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl range\u003c\/td\u003e\n\u003ctd\u003epH 3.5 - 10.5, digitally adjustable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.05 pH (+1 digit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating temperature\u003c\/td\u003e\n\u003ctd\u003e0-50°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity\u003c\/td\u003e\n\u003ctd\u003eBelow 80%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower input\u003c\/td\u003e\n\u003ctd\u003e100-240 V AC, 50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e150 x 85 x 40 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApprox. 0.78 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrode connection\u003c\/td\u003e\n\u003ctd\u003eBNC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eAM20300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003epH Monitor unit\u003c\/li\u003e\n\u003cli\u003ePlastic pH electrode with BNC fitting\u003c\/li\u003e\n\u003cli\u003eCalibration fluid for initial setup\u003c\/li\u003e\n\u003cli\u003eMains power adapter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhich Aqua Medic pH controller do I need?\u003c\/h3\u003e\u003cp\u003eIf you mainly need to know your pH and want a relay ready as a safety backstop, the pH Monitor's 5 A output is enough for a pump, solenoid or alarm.
