Bluelab Guardian Ph, Ec and Temperature Monitor The Bluelab Guardian Monitor will allow you to continuously control your water pH, conductivity and temperature all in one. The Guardian is specially designed for indoor cultivation. It can be hung on the wall or on a support bar. For everything that is problem with yellow leaves, growth delay, or anything else this tester will allow you to know the settings you need to change to meet the requirements of your plants. The Bluelab Combo Meter has two probes: a probe to control the pH a probe to control conductivity and temperature. All you need to do is place the probes in the nutrient solution and read the information on the Bluelab monitor. Advantages: Easy to read screens Measures pH, EC and temperature directly into your irrigation line No calibration required for conductivity and temperature Selectable values for conductivity and temperature Single button calibration for pH 7 and pH 4 Water resistant housing International power supply included Replaceable dual bond pH probe included Non-volatile memory (setting retained when power is lost) Technical specifications: pH measurement range: 0.0 - 14.0 EC measuring range: 0.0 - 5.0 Temperature range: 0 - 50 °C Accuracy and pH resolution: 0.1 pH EC Accuracy and Resolution: 0.1 EC Accuracy and temperature resolution: 1°C pH calibration: two points (pH 7.0 and pH 4.0 or pH 10.0) EC calibration: not required (factory calibration) Temperature calibration: not required (factory calibration) Power supply: 220 V plug
