Introduction Chauvin Arnoux PSD21
The PSD21 is a rugged laboratory pH-meter designed for general use.
The zero and slope of the pH can be adjusted manually using rotary buttons in order to clearly display the fundamental calibration concept and the characteristics of the electrodes.
Its ergonomics and rugged design make this one of the most popular pH-meters available.
For greater versatility, this instrument offers a 0-5 V analog output so that it can be hooked up to a recording device (flatbed plotter, logger). This analogueoutput also means that the instrument can be integrated into Computer-AssistedExperimentation environments.
Features
– Accurate measurement of pH and Redox concentrations quickly determines the characteristics of electrodes
Chauvin Arnoux PSD21 with a wide pH measurement range from 0 to 14 (Rs = 0.01 pH); Redox: ± 1,999 mV (Rs = 1 mV). Make simple pH measurements; more detailed assessment of the acid or base concentration of a sample. Ensure full conditions for the measurement results always have the highest accuracy.
– Manual temperature compensation with customizable range up to 100°C
MTC (manual adjustment) helps maintain temperature in equilibrium, optional stable temperature compensation for equivalent active hydrogen ion activity meets precise measurement requirements. Allows users to test the pH in different environments; manual temperature compensation to 100°C helps fulfill PH test requirements efficiently – much more accurately than before.
– PH calibration function from 1 to 2 points faster and more accurate measurement
Support users to make Ph measurement simpler and easier. The data value after many measurements made by the user has the highest accuracy. As for difficult sample cases, users can measure quickly and with less effort. The post-measurement assessments are also consistent and accurate.
– Compact design – handy and parameter display up to 2000 count
Chauvin Arnoux PSD21 makes handling manual adjustment requirements easy and convenient. Simple to use – compact and space saving; The LCD display allows the user to read the output data very clearly through the analog display – up to 2000 count counter. The application handles the post-measurement data better; Improved reliability for measurements – different job requirements.
– Compliant with NF EN 61010-1 — NF EN 61326 (Class B) – 2000m altitude limit
Chauvin Arnoux PSD21 dedicated to performing concentration measurements in solution medium; compliance assessment NF EN 61010-1 — NF EN 61326 (Class B) : applicable to electrical equipment; Operates from batteries or the mains with voltages up to 1000 V AC or 1500 V DC.
Class B – includes equipment for use in domestic facilities directly connected to the low voltage supply network; provide domestic environment. Allows users to have complete peace of mind in situations of measuring pH in water – conductive solutions. The highest level of safety is guaranteed, and at the same time, “Elevation Limit 2000m” supports good application measurements and functions even inside harsh working environment conditions.
