Hanna Multiparameter Probe HI1285-7 | pH, EC, TDS for HI9814 NO_MAINSTEM and an internal temperature sensorWhat the Hanna Multiparameter Probe Puts in One Body Four measurements, one thing to dip. The pH side uses a low temperature glass sensing bulb with a cloth junction and a maintenance free polymer gel electrolyte. There is no fill solution to top up. The EC and TDS side reads amperometrically across two stainless steel pins set into the same body. A temperature sensor sits inside as well, compensating both the pH and the conductivity readings.
