I. Overview

1. The ST873 pH electrode is specifically designed for on-line pH measurement in harsh industrial processes. It features a robust structure, with a solid-state reference electrode utilizing IonTrap™ (ion trap) technology, which extends the electrode's lifespan in harsh environments. The electrode body, including a 1" MNPT threaded connection, is made of corrosion-resistant Ryton (PPS) material. The reference electrode diaphragm is made of porous Teflon or wood material. Additionally, an optional built-in temperature probe is available for automatic temperature compensation, as well as an electrode head protection device and an ORP sensor head for ORP testing.

     

II. Technical Specifications:

pH Range: 0 ~ 14 pH

2. ORP Range: ±5000 mV

3. Temperature Range: 0 ~ 140℃

4. Pressure Resistance: 150 psig at 120°C (100 psig = 7 kg/cm²)

5. Reference Electrode: Ag/AgCl

6. Liquid Seal Material: Ryton, Teflon, wooden, or glass

7. Standard Cable Length: 7 feet

Section 3: Optional Accessories

     

1. Arch-shaped sensing head, coaxial Teflon or wooden diaphragm, primarily used for extremely harsh application environments, with excellent overall performance.

2. Flat head, coaxial Teflon diaphragm, primarily used for unrestricted flow testing, featuring self-cleaning properties.

3. Platinum-plated ring sensors, coaxial Teflon or wooden diaphragms, primarily used for ORP testing.
