Yieryi Pen Type PH Electrode Sensor

The Yieryi Pen Type PH Electrode Sensor is a high-precision tool designed for accurate pH measurement in laboratory and industrial settings. Featuring a BNC connector, this sensor ensures low-noise connectivity and reliable readings. With a pH range of 0 to 14 and a temperature range of 0-50ºC, it is suitable for a variety of applications. The E-201 model offers a composite electrode made from a pH electrode and a silver-silver chloride reference electrode, encased in a durable polycarbonate shell. Ideal for the chemical and pharmaceutical industries, this sensor requires activation by soaking in a potassium chloride solution before first use. Ensure accurate results by washing the electrode in distilled water before measurement. The E-201C variant allows for rechargeable use with an external reference solution.
