Versatile, compact design works in a field or laboratory setting

• pHTestr 20 features ±0.01 pH accuracy — suitable for most ASTM and EPA test procedures.
• A complete meter with key features at an economical price
• Replaceable, double-junction electrode sensors save time and money
• IP67-rated housing sits flat on the table and floats in water

• Waterproof pHTestr 20 is great for outdoor applications such as taking pH measurements in lakes and streams. Designed to float in water, you can even attach a line to the housing for easy retrieval. Valox® sensor housing resists most chemicals.
  
  The pHTestr 20 has a replaceable sensor for easy maintenance. Double-junction electrode sensor handles wastewater and solutions containing sulfides, heavy metals, and TRIS. Electrode sensor offers a clog-resistant Kynar® junction and a recessed, glass pH bulb to protect against breakage.
  
  The keypad clicks to confirm operation, and allows access to a variety of functions. Calibrate up to three pH points with the auto-buffer recognition at both USA and NIST standard buffers. Additional features include a automatic temperature compensation (ATC), hold function, auto-off function, self-diagnostic error messages, and a three-segment battery-life indicator.
   

  Meter includes protective plastic storage case, lanyard, and batteries.|
