HI12923 – pH Electrode for Direct Soil Measurement
Availability : กรุณาติดต่อสอบถาม
The HI12923 is a glass body, refillable, single junction pH electrode with a quick connect 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 HI12923 is ideal for pH measurements in soils and soil slurries. The HI12923 is designed for use with Hanna’s HI99121 portable pH meter.
