Waterproof Microprocessor TDSTestrs+ and ECTestrs+
Operate as both cup-style or dip-style tester, plus toggle to °C readings!
  Switch from conductivity (or TDS) to °C readings with the touch of a button
Waterproof, dustproof housing that floats is certifiable to IP67 standards
Replaceable sensor lets you reuse same meter body, saving you money
Automatic Temperature Compensation
Push-button calibration, Hold function, Auto-Off
These testers let you take readings two ways: simply immerse tester tip into sample, or pour a small amount of your sample directly into the sensor cup. Tester displays conductivity or TDS reading; switch to °C readings with the press of a button.
Valox® housing and stainless steel electrodes offer good chemical compatibility. Replaceable sensors let you reuse meter body without losing waterproof protection. Choose from six models in high range, low range or pure range. The "pure+" models have an extremely low range for pure water applications.
