Specifi cations
2724 DryLoc pH Electrode
General
Compatibility: Signet 2750 pH/ORP Sensor electronics
Process
Connection: ¾ in. NPT or ISO 7/1 R¾ threads
or Signet fl ow fi ttings
Wetted Materials: PPS, glass, UHMW PE, FPM
Performance
• Effi ciency: >97% @ 25 °C (77 °F)
Effi ciency indicates the "wellness" of a
new electrode. Effi ciency is measured by
comparing the actual slope (mV/pH) at 25
°C to the theoretical output of 59.16 mV/pH.
An effi ciency of 97% to 100% is equivalent
to a slope of 57.39 to 59.16 mV/pH.
• Range: 0 to 14 pH
Environmental
Pressure
• Operating:
-10 ºC to 65 °C (14 °F to 149 °F),0 to 6.9 bar (0 to 100 psi)
65 °C to 85 °C (149 °F to 185 °F),
Linearity derated 6.9 to 4.0 bar (100 to 58 psi)
Temperature
• Storage: 0 °C to 50 °C (32 °F to 120 °F).
CAUTION: The electrode glass will
be shattered if shipped or stored at
temperatures below 0 °C (32 °F).
The performance life of the electrode will
be shortened if stored at temperatures
above 50 °C (120 °F).
• Operating: -10 ºC to 85 ºC (14 ºF to 185 ºF)
Rel. Humidity: 0 to 95% indoor/outdoor non-condensing to
rated ambient
Shipping Weight: 0.25 kg (0.55 lb)
