• High ±0.01 pH accuracy
• Simultaneous pH and temperature (°C) display
• Suitable for most ASTM and EPA test procedures
• Double junction electrode ideal for dirty water, heavy sulfides, tris buffers and organics
• Increased reference gel volume offers significantly longer electrode life
• Certifiable to IP67 standards - waterproof and dustproof housing floats
• Replaceable sensor lets you reuse same meter body
• Automatic Temperature Compensation (ATC)
• Three point push-button calibration

Now you can have high ±0.01 pH accuracy in a waterproof pocket-sized instrument! The unique Testr displays pH and °C readings on a single large display. These instruments also feature a double junction electrode that is ideal for dirty water and solutions with heavy metals or other contaminants. Tester features a waterproof, dustproof housing that protects your instrument from rugged field or plant environments.

Ideal for quick checks of pH for all water and industrial applications. These rugged instruments provide rapid and reliable readings with excellent repeatability. Single junction electrodes are for clean water applications, and Double Junction provides extra protection in dirty water and industrial liquid applications.
