HANNA HI9811-5N PH METER

HI 9811-5 is a pH/ EC/ TDS waterproof meter designed for simplicity in taking pH, µ S/ cm, ppm ( mg/ L) and temperature measurements. both the HI 9811-5 and HI 9812-5 are ideal for hydroponics, greenhouses, farming and ground water applications. Due to the built-in temperature sensor, conductivity readings are automatically compensated for temperature changes. The temperature coefficient is fixed at 2% / ° C. The specially engineered HI 1285-5 pH/ EC/ TDS and temperature probe utilizes a fiber junction and gel electrolyte which provide a fast response and reduced contamination. This combination makes the HI 1285-5 particularly designed to withstand harsh environments such as fertilizer solutions. Features: Water resistant On-screen tutorial messages for calibration Switch parameters at the touch of a button Automatic Temperature Compensation for pH and conductivity Simple calibration; Dials located on the front panel makes calibration quick and simple, even for non-technical users BEPS ( Battery Error Prevention System) alerts the user in the event that low battery power could adversely affect readings Battery % displayed on startup Fast response probe included
