TQC Sheen pH Meter Kit – Portable pH and Temperature Meter

Accurate and Portable pH Testing for Industrial and Lab Use

The TQC Sheen HI0045 pH Meter Kit is a compact and easy-to-use handheld device designed for reliable pH and temperature measurements. Engineered for professionals who require accurate, repeatable data in the field or lab, this microprocessor-based instrument supports applications ranging from coatings and surface preparation to quality control in inks and water systems.

With an extended pH range from 0.001 to 14.00 pH, ±0.01 pH accuracy, and automatic or manual temperature compensation, the HI0045 delivers laboratory-grade results in a portable format. Calibration is fast and flexible, with up to five calibration points and multiple buffer group options (USA, NIST, Pb).

Whether you’re measuring the surface pH of metals before coating or assessing water quality in ink production, the HI0045 offers the tools you need in one complete kit—including batteries, protective rubber armor, and an easy-to-read LCD screen with intuitive four-key navigation.

Why Accurate pH Testing Matters

In surface preparation and coatings, improper pH levels can result in poor adhesion, corrosion, or coating failure. The HI0045 helps users verify surface conditions before application, ensuring compliance with international standards and extending product performance in critical environments.

How to Use the TQC Sheen HI0045 pH Meter

• Power on the device using the rubberized keypad.
• Calibrate using 2–5 standard buffer solutions based on your selected group.
• Insert the probe into the test liquid or surface.
• View pH and temperature results simultaneously on the digital display.
• Use the “Hold” function for convenience in fieldwork or tight environments.
• The unit will automatically shut off after 17 minutes to preserve battery life.

A portfolio thick with innovative testing devices

Across the Industrial Physics portfolio, we have a wide range of conductivity testing solutions. 

For example, there’s the Elite Pocket Tester, a multifunctional meter designed for conductivity, TDS, salinity, and temperature measurement. Then you could check out the ECCON700 Meter with its accurate conductivity and ATC probe.

Let our experience conduct your testing approach!

Over many decades of building conductivity testing devices, we’ve learned a lot of best practices. We share our insight across the knowledgebase section of our website. 

Here you’ll find lots of blogs relating to conductivity, like this one on measuring soluble salts using the Bresle patch method. Or this blog, which investigates how to find the thermal conductivity of gases.
