This Water Quality Meter is a 3-in-1 kit from Extech that includes all of the tools required to measure chlorine, pH, ORP and temperature. Store and recall as many as 15 readings. It automatically saves the last calibrated value and has automatic self calibration for chlorine and ORP; 1-,2- or 3-point buffer calibration for pH.

The features included in this water quality meter include data hold, auto shut-off and low battery indicator. A smart chip predicts pH electrode performance and indicates when it needs replacement. Units indicate when pH electrode needs recalibration. Large 3-1/2" display with bargraph simultaneously shows ppm or pH and temperature in °C or °F. This water quality meter also has automatic temperature compensation and directly reads total chlorine from low detection limits. Waterproof housing protects meter and floats. The unit weighs 3.85 oz. and measures 6.8"H x 1.6"W x 1.4"D. It operates on four SR44W button batteries.

Calibration: NIST-Traceable Calibration available for pH Meters. Meets ISO/IEC 17025 Accreditation.
