  Simple to calibrate with automatic standard recognition
  Rugged IP67-rated housing is waterproof, dustproof, and floats in water with sensor cap on
  Leakproof cap with fill line functions as a sample/calibration and hydrating cup

  Auto shutoff extends battery life
  Features a flat probe—ideal for surface or micro-volume testing

This pocket-sized tester has a replaceable single-junction sensor which can be easily switched out, allowing you to save money by using the tester body over and over again. A large LCD makes viewing measurements easy and features a three-color backlight indicating operational mode—blue for measurement, green for calibration and red for alarm condition.

Additional features include hold function to lock in measurements, self-diagnostic error message, and status icons for measurement stability and low battery voltage. The IP67-rated housing features an easy-to-grip design and floats if accidentally dropped in water when sensor cap is on. Powered by four AAA batteries, the tester can operate up to 400 hours continuously. To conserve power, the unit will auto power-off after 8 minutes of nonuse.

The pH tester features up to 3-point pH calibration with NIST or US auto buffer recognition, a pH range from -2 to 16 with an accuracy of ±0.01 pH, and automatic temperature compensation. It supports a ORP probe (sold separately).
