HM Digital (SP-P2) Replacement pH Sensor for PH-200

The HM Digital SP-P2 is a direct-fit replacement pH sensor designed specifically for the PH-200 meter, featuring a replaceable glass sensor and reference tube electrode assembly. This OEM replacement restores full accuracy and function to your pH testing equipment across water purification, hydroponics, laboratory, and industrial applications.
SPECIFICATIONS

HM Digital SP-P2 Sensor Technical Details

Model Number SP-P2
Compatible Meter HM Digital PH-200
Sensor Type Replaceable glass sensor with reference tube electrode
pH Range 0 - 14 pH
Temperature Range 0-80 °C (32-176 °F)
Resolution 0.01 pH
Accuracy ±0.02 pH
Housing Rating IP-67 Waterproof (submersible)
INSTALLATION & USE

Replacing Your PH-200 Sensor

  1. Unscrew and remove the old sensor module from the bottom of your PH-200 meter body by rotating counterclockwise.
  2. Thread the new SP-P2 sensor into the meter housing and tighten hand-tight until secure. Do not overtighten.
  3. Remove the protective cap from the sensor tip and rinse the glass bulb with distilled water before first use.
  4. Perform a three-point calibration using pH 4.0, 7.0, and 10.0 buffer solutions following the PH-200 calibration procedure in your meter manual.
  5. Store the sensor with the cap on and ensure the sponge inside remains moist with storage solution between uses to extend electrode life.
COMPATIBILITY

Designed for HM Digital PH-200 Meters

The SP-P2 replacement sensor is engineered exclusively for the HM Digital PH-200 handheld pH and temperature meter. This sensor is ideal for water purification systems, reverse osmosis monitoring, wastewater regulation, hydroponics, aquaculture, pool and spa maintenance, colloidal silver production, laboratory testing, boiler and cooling tower applications, coffee roasting, agriculture, and ecology monitoring. The replaceable design allows you to maintain your existing PH-200 meter without purchasing a complete new unit when sensor performance degrades over time.

🔧 Pro Tip: Keep the protective cap filled with pH electrode storage solution (not distilled water) between measurements. A dried-out sensor will give erratic readings and shorten electrode life significantly. If the sensor has dried out, soak the glass bulb in storage solution or pH 4.0 buffer for at least 30 minutes before recalibrating.
