ORP57 Pocket-size ORP / Temperature Meter with Replaceable Electrode by Milwaukee

Combination waterproof testers with advanced functions also include the new model pH58 for simultaneous pH and ORP measurements and temperature, which is continuously displayed on the dual level LCD.

It shows readings in an extended range from -2.00 to 16.00 pH or ±1000 mV and simultaneously shows temperature from -5.0 to 105.0°C or 23 to 221°F.

The pH58 has a stability indicator and hold feature that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations.

Calibration is performed automatically at 1 or 2 points using standard or NIST buffers.

The modular design allows easy electrode and battery replacement.

WD-35634-06 EcoTestr™ EC1 Waterproof Pocket Tester by Oakton

Designed to be durable and easy to use

These economical, simple-to-use pocket testers quickly measure conductivity, TDS, or salinity levels accurately while simultaneously displaying the temperature. A large dual-line display makes viewing measurements easy and features indicators for measurement stability, calibration, and battery life.

Additional features include a long-lasting, durable electrode with polymer reference electrolyte, auto recognition of calibration standards, and self-diagnostics. The IP67-rated housing features an easy-to-grip design and floats if accidentally dropped in water when sensor cap is on. The testers, powered by four AAA batteries, can operate up to 400 hours continuously. The unit will auto power-off after 8 minutes of nonuse to conserve power.

• View measurements clearly on large LCD
• Rugged IP67-rated housing is waterproof, dustproof, and floats in water
• Leakproof cap with fill line functions as a sample/calibration and hydrating cup
• Secure attach a lanyard to prevent losing or dropping in the field
• Auto shutoff extends battery life
