Sensorex pH3000 Research-Grade pH Sensor

Sensorex pH3000 Research-Grade pH Sensor (Refillable)

When accuracy and repeatability are critical, such as in pharmaceutical or drinking water applications, the ideal pH electrode will quickly deliver stable measurements. The pH3000 is pH meter replacement probe specially designed to respond quickly and accurately to rapid temperature changes. The high sensitivity internals also make these electrodes the best choice for low ionic samples. The double junction reference design prevents contamination, allowing pH testing in samples containing heavy metals, proteins and enzymes, or TRIS buffer.

  • Our most sensitive laboratory electrode: accurate to 0.04 pH in tests across full recommended temperature range

  • Easily maximize measurement repeatability: Rapid renew reference system for quick refilling

  • Extensive chemical compatibility: Constructed with durable Ultem®, proven in a range of chemical conditions

  • Ideal for difficult sample types: Double junction reference protection for testing samples containing heavy metals, TRIS buffer, and other contaminants

  • Virtually unbreakable: removable bulb guard protects pH glass and strain relief prevents damage to cable connection

  • Ready for wet or corrosive environments: BNC boot protects meter connection

  • Compatible with various meters: Versatile replacement probe works with any meter accepting a BNC pH probe

Recommended for: Low ionic samples, medical and pharmaceutical research, biological samples, samples containing heavy metals
