Bluelab Guardian PH, ECC and Temperature Monitor The Bluelab Guardian monitor will give you 24 hours continuous control of the pH, conductivity and temperature of your water all in one. The Guardian is specially designed for indoor cultivation. It can be hung on the wall or on a support bar. For anything with yellow leaves, growing delay, or anything else this tester will allow you to know the parameters to be changed to meet the requirements of your plants. The Bluelab Combo Meter has two probes: A probe to control the pH a probe to control the conductivity and temperature. Simply place the probes into the nutrient solution and read the information on the Bluelab monitor. Advantages: Easy to read screens Measures pH, EC and temperature directly in 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 link pH probe included Non-volatile memory (setting retained when power is lost) Technical specifications: pH measurement range: 0-14.0 EC measurement range: 0 - 5.0 Temperature range: 0 - 50 °C Accuracy and Resolution PH: 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 socket
