FiveEasy FP20-Std-Kit pH meter METTLER TOLEDO Thanks to FiveEasy's intuitive operation, elegant desi (more)gn and simple data export functions, you can measure in complete comfort. Ideal for laboratory applications, the FiveEasy and FiveEasy Plus worktables provide high-quality pH/mV or conductivity measurements with a simple click. Compact in design and equipped with various data export capabilities, the FiveEasy series instruments are the perfect companion for obtaining reliable measurement data, at an excellent quality/price ratio. SIMPLE MEASUREMENT Impeccable pH measurements, fast and efficient thanks to a large, well-structured display and an intuitive button layout. COMPACT, SPACE-SAVING DESIGN Thanks to its compact design and removable sensor holder (stowable on the side of the meter), the instrument takes up little space on the workbench. The rectangular structure allows easy stacking of the instrument and is very light: only 0.63 kg for 227x147x70 mm of dimensions. WHY "P" PLUS? The Five Easy Plus pH-meter automatically recognizes the buffer solution, thus avoiding possible calibration errors; has a higher pH and temperature range; higher accuracy; calibration storage of up to 200 measurements; RS232, USB connection. Specifications - FiveEasy pH meter FP20-Std-Kit Once you have purchased the product, you will find simple and clear videos on how to set up and calibrate your FiveEasy ph-meter:

Convenient Transportation of Small Mass Standards The mass standards tweezers are tongs/ pliers that (more) will enable you to conveniently and precisely grasp and transport small mass standards. With it, you can easily and quickly place or lay an object (for example, a mass standard) on the pan and remove it from the pan. The tweezers protect the mass standards from finger grease, moisture and other factors that interfere with the measurement. It is indispensable in the daily use of laboratory balances.
