pH meter - thermometer Nitron - pH
pH meter - thermometer Nitron - pH Designed to measure the activity of hydrogen ions (pH), redox potential Eh and temperature of aqueous solutions. The operating principle of the device is based on the use of the direct potentiometry method. When measuring the pH of whole milk, the pH is converted into the titratable acidity of milk in degrees Turner (°T). Can be used as a high-resistance millivoltmeter: when measuring EMF from the output of the electrode system; with potentiometric titration. Benefits: Shockproof housing. Large informative LCD display. Non-volatile memory, built-in clock and user notepad. Automatic graduation from 1 to 6 points. Powered by 220 V mains or AA batteries. Manual or automatic temperature compensation. Automatic detection of the absence of a temperature compensator connected to the device. Ability to connect to a PC to view measurement results. Possibility of connecting up to 5 measuring electrodes using a switch. Basic package: Nitron-pH device – 1 pc.; power supply – 1 pc.; temperature compensator – 1 pc.; AA battery – 2 pcs.; power supply – 1 pc.; calibration solutions pH=4.01 and pH=6.86 (200 ml each); cord for communication with PC – 1 pc.; working documentation.
