pH Pen

Take quick, accurate readings on concrete and carpeted surfaces. Flat surface electrode measures pH on concrete, carpets and solid objects. CAL alerts signals need to recalibrate. 

• Flat surface electrode evaluates pH on concrete, carpet, solid objects
• CAL alert advises when to recalibrate to ensure accuracy
• RENEW indicator eliminates guesswork;you will know when to replace your electrode
• Memory records and recalls 15 sequentially tagged readings to monitor changes over time
• Analog LCD bar graph reflects trends in acidity or alkalinity
• Simultaneous pH (0.00 to 14.00pH) and temp. (23 to 194ºF) display
• High accuracy of +0.01 pH
• 1-, 2-, or 3-point calibration instinctively recognizes buffer solutions
• Automatic temperature compensation feature
• Display indicates when a reading has stabilized
• Data hold, auto power OFF and low-battery indicators
• Waterproof design floats in water to protect unit in wet environments
• PH100 meter includes flat surface pH electrode, protective sensor cap, sample cup w/cap, 4-SR44 button batteries and 48-inch neck strap

**Though the pH pen will come calibrated, re-calibration will be necessary from time to time. Calibration kits (CA-PHPCK710 or CA-PHPCK) must be ordered separately.
