The heart of a pH measuring loop is the electrode system.Yokogawa has designed a wide range of electrodes to ensure,this heart keeps beating under the most severe conditions.
Dome shape membrane in combination with L-glass ensures
mechanical strength and chemical resistance. Recommended
in higher temperature applications （continuously > 70ºC）.
• Suitable in hot caustic applications.
• Suitable in processes with traces of HF.
• pH, temperature range: 0 to 14 pH, 25 to 130ºC.
• Glass resistance （25ºC）: 600 to 900 MΩ.
• High quality Ag/AgCl pin reference system.
Note: The resistance may not exceed 1000 MΩunder
measuring and calibrating conditions （according DIN the
resistance of the glass may not exceed 1GΩ）. As a general
rule, the glass-resistance will increase by 100% with
every temperature decrease of 10ºC （likewise, the glass
impedance will decrease bij 50% with every temperature increase of 10ºC）.
普通型：SM21-AG2、SM21-AG4、SM21-AG6、SM21-AL2、SM21-AL4、SM21-AL6
高溫型、耐化學(xué)腐蝕：SM21D-AG2、SM21D-AG4、SM21D-AG6、SM21D-AL2、SM21D-AL4、SM21D-AL6
