The HI1292D is a glass body, refillable, single junction pH electrode with a DIN connector. This electrode has a triple ceramic junction in the outer reference cell and the conic pH sensing tip is made with low temperature glass. There is an integrated amplifier and built-in temperature sensor for automatically temperature compensated pH readings.
The design consideration for the HI1292D is ideal for pH measurements in soils and soil slurries. The HI1292D is designed for use with Hanna's HI99121 portable pH meter.
Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.
The HI1292D uses low temperature (LT) glass, conic bulb, glass body, triple ceramic junction, and is refillable with 3.5M KCl + AgCl.
