Overview

The Meascom pH and ORP  Water Testing Kit is a complete handheld water testing system designed for applications where pH control and oxidation–reduction potential (ORP) are critical to water quality, safety, and treatment effectiveness.

Unlike bare meters sold without the essentials, this kit includes everything required for correct calibration, use, and probe care — removing guesswork and ensuring reliable results from day one.

Measured Parameters

• pH
• ORP (Redox potential, mV)
• Temperature (°C)

(Only supported parameters are documented and warranted by Meascom.)

---

Measurement Ranges

• pH: 0.00 to 14.00 pH
• ORP: ±1200 mV
• Temperature: 0 to 60 °C

---

Accuracy

• pH: ±0.01 pH
• ORP: ±5 mV
• Temperature: ±0.5 °C

---

Key Applications

• Swimming pools and spas
• Drinking water testing
• Water treatment and disinfection monitoring
• Environmental and field sampling
• General water quality assessment

ORP measurement provides a practical indication of oxidising disinfectant activity, making it especially valuable where free chlorine effectiveness matters.

Why This pH and ORP Water Testing Kit Is Different

✔ Correct calibration without waste

Dedicated calibration cups prevent buffer contamination and allow calibration with minimal solution volumes.

✔ Proper probe care included

pH probes must never be stored dry or in distilled water. Including KCl storage solution significantly extends probe life and response speed.

✔ ORP done properly

ORP accuracy depends heavily on correct reference solution. A 650 mV ORP standard is supplied — not assumed.

✔ No hidden extras

No additional buffers, solutions, or accessories are required to begin accurate measurements.

Calibration Guidance (Simple & Practical)

• pH calibration:
  Two-point calibration using pH 6.86 and pH 9.18, ideal for neutral to slightly alkaline water applications.
• ORP calibration:
  Single-point calibration using 650 mV ORP solution.

This approach balances accuracy, speed, and real-world usability.

Operating Features

• Automatic temperature compensation (ATC)
• Clear backlit LCD display
• Hold function for stable readings
• Auto power-off
• Waterproof housing suitable for field use

---

Model Identification

• Model: MC-PH-ORP-Kit
• Configuration: pH + ORP + Temperature
• Brand: Meascom

Typical Use Cases

• Pool operators monitoring sanitiser effectiveness
• Facility managers checking water quality
• Technicians validating treatment processes
• Environmental field testing

Final Note

The MC-PH-ORP-Kit is supplied as a matched system, not a loose collection of parts. Every component — meter, probe, buffers, ORP solution, cups, and storage solution — is included because it directly affects measurement accuracy and probe lifespan.

That’s how you measure with confidence.
