• The Swiss Spear pH Sensor is designed for professional pH measurements of soft-solid samples such as cheese, fruit, sushi rice, soil, meat, cosmetics, etc. (also works great for regular liquid pH testing). It is even replaceable so that you don't have to buy a whole new meter once the probe is aged over time.
• Easy Auto. Calibration with buffer recognition; Auto Temp. Compensation (ATC) which ensures accuracy in variant temperatures (0-50.0°C)
• Auto recognition of stable values (optional auto hold function available) improves consistency so you don't have to guess when to manually hold measurement
• Large Clear LCD screen with 3 backlit colors (indicating 3 different modes), dual display of temp./pH, and indications of completed calibrations and stable readings
• Complete kit with ready-to-use calibration solutions, calibration bottles, storage solutions, AAA batteries, a quick manual, and a lanyard all in a portable carrying case
