HI1285‑61 polypropylene body amplified pH electrode with built‑in EC/TDS and temperature sensors
The HI9813‑61 includes the HI1285‑61 multi‑sensor probe, combining pH, EC, TDS, and temperature measurement into a single durable polypropylene body. The integrated design connects to the meter through an 8‑pin DIN connector, ensuring secure communication and stable readings during field use.
Amplified pH electrode
The built‑in amplifier protects the pH signal from electrical noise, a common challenge in environments with pumps, motors, and lighting systems. This ensures more consistent pH measurements in greenhouses and hydroponic setups.
Amperometric EC/TDS sensor
The EC/TDS portion of the probe uses an amperometric sensor, applying an alternating voltage across stainless steel pins. Conductivity increases as dissolved salts rise, allowing accurate nutrient and water quality monitoring.
Polypropylene body
The rugged polypropylene housing protects all sensors in a single maintenance‑free design. The gel‑filled pH electrode eliminates the need for refilling, making the probe ideal for frequent field use.
- 3 sensors integrated into one probe
- Pre‑amplified pH electrode reduces electrical interference
- Gel‑filled, maintenance‑free pH design
