IntelliCAL PHC281 酸鹼度電極內建溫度感測器和 1 公尺電纜。專門為快速反應和穩定測量一般水質或低離子強度 (LIS)、超純水、髒污水、TRIS 或高懸浮固體含量樣品等困難水樣的 pH 值而設計。
The IntelliCAL PHC281 is a standard combination pH electrode, robust plastic body, refillable with built-in temperature sensor and 1 m cable. PHC281 is intended for laboratory use and specially designed for fast response and stabilisation to measure pH in general purpose water quality applications or in difficult samples such as low ionic strength (LIS), ultrapure, dirty, TRIS, or high-solid content samples.

IntelliCAL ISEF121 數位複合型氟離子選擇電極 (ISE)，具備不可再填充的單接面參考和內建溫度感測器。適合測量飲用水、廢污水和一般水質的氟化物濃度。ISEF121 的固態感測器設計無需更換薄膜，並容許 ISE 進行乾燥儲存。
The IntelliCAL ISEF121 is a digital, combination fluoride ion selective electrode (ISE) with a non-refillable, single junction reference and built-in temperature sensor. The ISEF121 electrode is intended for laboratory use. The ISEF121 is ideal for measuring fluoride concentrations in drinking water, wastewater, and general water quality applications. The ISEF121’s solid-state sensor design eliminates membrane replacement and allows for dry storage of the ISE.

Range 量測範圍 : 0 - 14 pH
